Since the Great Financial Crisis, central banks have been facing a triple challenge: economic, intellectual and institutional. The institutional challenge is that central bank independence - a valuable institution - has come in for greater criticism. This essay takes a historical perspective and draws parallels with the previous waxing and waning of central bank independence. It suggests that this institution is closely tied to globalisation, as both spring from the same fountainhead: an intellectual and political environment that supports an open system in which countries adhere to the same principles and governments remain at arm′s length from the functioning of a market economy. This suggests that the fortunes of independence are also tied to those of globalisation. The essay then proceeds to explore ways that can help safeguard independence. A key one is to narrow the growing expectations gap between what central banks are expected to deliver and what they can actually deliver. In that context, it also considers and dismisses the usefulness of recently proposed schemes that involve controlled deficit monetisation.
|“Autonomy and freedom from political control are desirable for all Central and Reserve Banks”
(Montagu Norman, 1921)
|“I assure Ministers … at all times … to do what they direct us as though we were under legal compulsion”
(Montagu Norman, 1936)
It was not supposed to be this way. During the Great Moderation, economists believed they had finally unlocked the secrets of the economy. We had learnt all that was important to learn about macroeconomics (Blanchard (2008)). Central banking could aspire to be boring (King (2000)). It was the same kind of heady feeling that had led some political scientists to declare “the end of history” (Fukuyama (2002)).
Then came the Great Financial Crisis (GFC) of 2007–09 and the Great Recession. The near collapse of the financial system did not just bring down the economy, it toppled the foregoing set of intellectual convictions. And, slowly but surely, it provided fertile ground for questioning the wisdom of those who had presided over the debacle. Recall the Queen’s famous question: “Why did nobody see it coming?” The Great Moderation had proved to be, at least in part, a Great Illusion.
Once the crisis struck, central banks rose to the challenge. They pulled out all the stops to avoid a repeat of the Great Depression. And they succeeded. They adapted the time-honoured lender of last resort function to the new economic realities – acting, in effect, as dealers (market-makers) of last resort (Mehrling (2011)). Partly as a result, greater powers in regulation and supervision were conferred on them, including a key role in macroprudential frameworks, reversing a trend dating back to the rise of inflation targeting.
Fast forward to today and the picture is quite different. Thanks to central bank actions in particular, the global economy has recovered. Economies have been close to, or even beyond, standard estimates of full employment. And price stability, by equally standard definitions, prevails. True, there is talk of a possible recession. But recessions are part of the physiology of a market economy, which every now and then has to take a breather; sooner or later they must come. “Reculer pour mieux sauter,” as they say in French.
Yet, concerns remain. Central banks have run low on room for policy manoeuvre (Graph 1). Their balance sheets have bloated to an unprecedented size. Interest rates have never been as low in nominal terms and never as negative for as long in real terms, not even during the Great Inflation era. Looking ahead, they are expected to remain so for the foreseeable future. Indeed, the amount of sovereign and corporate debt trading at negative nominal interest rates has reached a peak of some $17 trillion, or 20% of world GDP. What was unthinkable just a few years back is now the norm. Such rates have been in part the result of central banks’ strenuous efforts to push a stubbornly low inflation back towards the 2% targets. What’s more, debt – both private and public – is actually higher globally in relation to GDP than pre-crisis. Historically, public sector debt has been higher only during wartime or its immediate aftermath.
Against this backdrop, central banks have been facing a triple challenge (Borio (2011)). Economic: by their own standards, they consider low inflation a sign that they are failing in their mandated task, while justifiable questions linger about what they could do to tackle the next recession. Intellectual: the previous compass has proved unreliable. Inflation has been too unresponsive to aggregate demand pressures; central banks have discovered they know how to bring it down, but are less certain about how to push it back up. Their models for the economy have failed them.2 Last but not least, institutional: critics have questioned central banks’ wisdom and the value of their independence in setting policy, after its rapid ascendency in the 1990s (Graph 2, left-hand panel). These doubts have been voiced particularly in countries where the value of an open multilateral global economic order has come under attack. The growing number of press articles discussing central bank independence testifies to this challenge (Graph 2, right-hand panel).3
In my presentation today, I would like to offer some personal reflections on these challenges and suggest a possible way forward. My main thesis is threefold.
First, paradoxically, the economic and intellectual challenges facing central banks have taken root in the seismic developments that have yielded most of the economic gains since the early 1980s – and particularly in their profound impact on inflation and the business cycle. These developments include the wave of globalisation as reflected in open trade and financial markets. This has created an environment conducive to stubbornly low inflation and to large financial expansions and contractions (cycles) – which, in turn, has vastly complicated central banks’ pursuit of their mandates in the monetary and financial spheres, retracing their experience during the previous globalisation wave that ended with the Great Depression. Intellectual convictions have naturally crumbled too.
Second, the intellectual and political zeitgeist that supports globalisation also supports central bank independence.4 It is unsurprising that, as globalisation has come under threat, central banks have been facing an institutional challenge to their independence, just as they did in the 1930s. At the time, central banks were blamed for the crisis; today, while not fully escaping such criticism, critics blame them for the side effects of the extraordinary policies still in place designed to push inflation up towards targets, resent them for the power they have gained, and see them as a symbol of an elite-driven open economic order.
Finally, while central bank independence and globalisation are closely tied, there are specific steps that can be taken to safeguard this valuable institution. Ultimately, independence is simply a means to an end; as such, it is not a right and must be earned by retaining public legitimacy. This is not just a matter of how central banks perform their tasks, namely being transparent and accountable. It is also a matter of what it they do and, in particular, whether they succeed in meeting expectations. A key step towards retaining independence would be to seek to reduce the growing “expectations gap” between what central banks are expected to deliver and what they can deliver. This will help address the triple challenge of the times. But the difficulties involved should not be underestimated. And the risk of a new form of fiscal dominance, de facto voiding independence, looms large.
Let me first address the economic-cum-intellectual challenge. I will then examine the institutional challenge before turning to some suggestions about the way forward.
The historical phase that started in the early 1980s and gathered momentum thereafter has become known as the second wave of globalisation. The analogy is with the first one, which took shape, roughly speaking, between the 1870s and World War I and which staggered on until the 1930s, when the Great Depression struck.
In the second wave, financial markets were liberalised, both domestically and internationally. By the early 1990s, the transformation from a government-led to a market-led global financial system was largely complete (Padoa-Schioppa and Saccomanni (1994)). And with the fall of the Berlin Wall in 1989 and the opening of China and the emerging market economies, the long march of trade liberalisation took a major leap forward. Some 1.7 billion people were able to join the global labour force.
This momentous change paved the way for much of our postwar prosperity. The dampening effect of the current trade dispute on the global economy illustrates this in spades. At the same time, the change had a major influence on business fluctuations, which changed remarkably in character from those that prevailed during the Great Inflation era. Two effects stand out.
First, the change provided ample scope for the unstable forces within the financial system to take hold. I have in mind the financial expansions and contractions (or financial cycles) that reflect the interaction of loosely anchored perceptions of value and risk, on the one hand, and liquidity constraints, on the other (Borio (2014a)). Such forces had been kept at bay during the previous financial repression phase. The most relevant financial cycles for economic activity within countries take the form of medium-term fluctuations in credit and property prices. But there is also a global financial cycle, which waxes and wanes across borders through gross capital flows (Rey (2013)) and which can interact with the domestic ones (Aldasoro et al (2019)).
Second, trade integration and the entry of new low-cost countries put downward pressure on inflation. Here I am not referring to the relative importance of domestic and global slack in the inflation process (eg Auer et al (2017)) – a cyclical phenomenon. I have in mind the convergence in unit labour costs when exchange rates do not take the brunt of the adjustment and also labour’s and firms’ loss of pricing power as markets become more contestable, weakening second-round effects (Borio (2017)). In turn, quickening technological innovation has amplified and reinvigorated the impact of globalisation. Think of global value chains, as distance shrunk, as well as of the substitution of capital for labour and of the so-called Amazon effect.
Paradoxically, while taking root in fundamentally positive forces, these changes in business fluctuations – financial cycles alongside structural disinflation pressures – sprang challenges from unsuspected quarters. The authorities were slow in recognising them and in adjusting policies accordingly. For one, prudential countermeasures lagged behind. There was too much trust in the self-equilibrating capacity of the financial system and the economy at large (eg Greenspan (2005)). In addition, monetary policy failed to adapt to the new environment. A combination of a focus on near-term inflation and progressive disregard for monetary and credit aggregates meant that there was no reason to tighten during strong financial expansions as long as inflation remained low and stable.5
What is the evidence for all this? I have examined this extensively in previous work and speeches (eg Borio et al (2019)). It is fair to say that the notion of the financial cycle has become part of the furniture, as it were. It is, for instance, at the core of the post-crisis macroprudential frameworks. By contrast, the role of globalisation and technology in the inflation process is still more controversial.6 If you asked any entrepreneur, fearful of losing market share, or worker, fearful of losing their job, the hypothesis would appear self-evident. But it is less appealing to the profession, focused on models of inflation that rely on domestic slack plus a direct role for expectations – although one may legitimately wonder whether the fear of loss should not trump expectations. Such models pay too much attention to demand forces and leave no room for the slow-moving supply factors that can result in secular disinflationary pressures, for any given degree of economic slack.
What is undeniable, although yet to be fully appreciated, is how the nature of recessions has changed (Graph 3). Until the mid-1980s, a rise in inflation would induce central banks to tighten substantially, which helped trigger the downturn; at the same time, the expansion and contraction in credit or the financial cycle remained muted. Since then, the bust of a previous financial boom has coincided with relatively stable inflation and a mild monetary policy tightening. You could say that we have shifted from inflation-induced to financial cycle-induced recessions.
In recent research, we have found more formal supporting evidence (Borio et al (2018, 2019)). Since the mid-1980s, in a large set of advanced and emerging market economies, financial cycle proxies outperform the popular yield curve as indicators of recession risk.
Look back and the similarities with the first globalisation wave are more than just a coincidence. Then, as now, financial markets and trade were liberalised. Volatility aside, linked to the composition of output, inflation was quite low and stable. In fact, mild deflation up to 1896 was followed by mild inflation thereafter. Financial cycle-induced recessions and financial crises were the norm.7 And central banks followed a rather passive policy rule: they kept interest rates roughly constant until the internal or external convertibility constraint came under pressure, thereby providing no brake against financial expansions.8
To my mind, the changing nature of the inflation process and of business cycles largely explains the post-crisis economic and intellectual travails of central banks. Like any other major financial crisis, the GFC ushered in a slow and prolonged recovery from a sharp downturn: painful deleveraging played itself out and resources shifted back, no less painfully, from overblown sectors, such as real estate and finance, to the others.9 At the same time, the tailwinds of globalisation and technology, which had helped central banks keep a lid on inflation pre-crisis, turned into strong headwinds post-crisis. They complicated central banks’ attempts to push inflation back to the pre-crisis targets and resulted in prolonged ultra-low interest rates and swollen balance sheets. They invalidated the previously well tried compass.
In such an environment, the economic and intellectual challenges central banks face have gone hand in hand with an institutional one: detractors have called central bank independence into question. Press articles on the topic have been multiplying (see also Graph 2).10 Policymakers, politicians and academics alike have been increasingly reflecting on the issue. This conference is just another example of the trend. And all this criticism creates a challenge also for those who, like me, value that independence.
There are three sets of factors behind the institutional challenge.
The first relates to policy measures.
In the monetary sphere, 10 years after the GFC, emergency monetary policy measures are still in place, as underlined by the condition of central bank balance sheets and prevailing interest rates. Moreover, if anything, the prospect is for the phenomenon to intensify at least in the near term. Central banks have eased again around the world, through both quantities and interest rates (BIS (2019a)).
This state of affairs has had two effects. On the one hand, it has drawn attention to distributional issues, be these in terms of wealth and income, creditors and debtors or the young and the old.11 While monetary policy has always had distributional effects, they become much more salient once policy tools reach unprecedented settings.12 On the other hand, this has blurred the line between monetary and fiscal policy, and debt management (Borio and Disyatat (2010)), as balance sheet policies can only be properly understood in the context of the consolidated public sector balance sheet, combining the government and the central bank.13 Critics have variously expressed concerns about financing governments through large-scale debt purchases,14 about the policies’ impact on credit allocation, as central banks have purchased private sector assets or have subsidised banks, or about the huge increase in foreign currency reserves, which tend to be seen as war chests that could be used for more useful purposes, despite their critical macroeconomic function.15
In the prudential sphere, the GFC has resulted in central banks playing a bigger role in financial regulation and supervision. Detractors argue that the institution has become too powerful and, again, that they are responsible for measures with clear distributional consequences. Examples include macroprudential tools, valuable as they undoubtedly are.16 For instance, loan-to-value ratios and debt-to-income ratios strengthen resilience and can help contain financial imbalances, but they also reduce the access to finance of younger and less well off people.
The second set of factors relates to policy outcomes.
For one, despite having managed the crisis successfully and having played a key role in stabilising the economy, they have not fully avoided criticism. Some of those critics have seen the emergency measures as favouring the interests of the financial sectors; others have regarded central banks as having contributed to the build-up of vulnerabilities. This was either through accommodative monetary policy17 or through inadequate banking regulation and supervision, where central banks were responsible for these areas.18
In addition, some argue, independence is now less valuable. If high inflation was the main reason to confer independence in the first place, what is the point of having it now, when the problem is actually how to push inflation up towards central banks’ targets?19 And if one reason for independence was the need to resist the government’s temptation to exploit artificially cheap finance, why is this still relevant now if, in seeking to boost inflation, central banks have willingly driven interest rates to extraordinarily low, sometimes negative, levels?
The third set of reasons relates to policy perceptions.
Since the GFC, an expectations gap has grown between what central banks can deliver and what they are expected to deliver. Central banks are not just expected to fine-tune inflation, but also to take care of output and employment, to avoid all recessions and, for many, to be the prime engine of growth. Paradoxically, this largely reflects the fact that central banks have taken the brunt of the burden of supporting the recovery – the “only game in town” syndrome (El Erian (2016)). It looks as if people have come to believe the economy is a simple machine and the interest rate lever is sufficient to do the job. This can only be a recipe for disappointment. As a result, if growth falters and central banks are unable to restore it, detractors will accuse them of not doing enough and for misusing their independence.
More generally, the sentiment against globalisation and the elites, seen as its guardians and symbol, has grown. Those voicing that sentiment tend to regard central bankers as members of a cosmopolitan elite, capable of moving what appear to be unimaginably vast sums of money within and across countries in defence of the interests of a powerful and unrepentant financial sector, all to support the status quo.20
A look at history indicates that the link between independence and globalisation is indeed quite close. Many consider the previous globalisation era as the heyday of central bank independence.21 It was back then that Montagu Norman, Governor of the Bank of England, dreamt of an independent central banking community.22 And the principle of central bank independence became “engraved in the tables of the League of Nations” (Toniolo (2010)). Independence was the gospel that the dominant countries preached and followed around the world.23 It was only natural that when the Great Depression shattered that world, central bank independence suffered the same fate.
What explains the link? For one, globalisation and independence spring from the same intellectual and political fountainhead: support for an open system in which countries adhere to the same principles and governments remain at arm’s length from the functioning of a market economy. Independence then acts as both a signal of the adherence to those principles and a mechanism to reassure markets of that adherence: governments will not interfere.24 Conversely, those intellectual and political strands that oppose globalisation – be they from the historical left or the nationalistic right – tend to see little value in independence, as they do in checks and balances more generally.
This indicates that the link between central bank independence and inflation control is of more recent vintage; independence has deeper roots. In the gold standard days, inflation was not a threat. More recently, the pursuit of price stability, and central bank independence as a way of underpinning it, have played the same role as support for convertibility did during the previous wave of globalisation.
One significant difference between the two historical periods is the immediate reaction to the financial crisis. In the 1930s, central banks were often blamed for the slump – just as they have been by the current generation of central bankers (Bernanke (2002)).25 In the aftermath of the GFC, and despite some criticism of their role, they were initially rightly held up as the saviours of the economy; heroes, not villains. The open global economic order survived the shock remarkably well. But as the legacy of the crisis has lingered, and the anti-globalisation sentiment has grown, similar forces as those prevailing in the aftermath of the Great Depression appear to have emerged, with a lag.
This deep link between central bank independence and the political environment suggests that, in a fundamental sense, independence is “endogenous”.26 It is an institution that reflects more basic societal, or at least political, preferences.27 For very much the same reason, imposing it on an unreceptive environment is unlikely to produce the desired results.28
What does all this suggest for the future of central bank independence? It suggests that its future could well be tied to the future of the current open global economic order. The probability of having substantive central bank independence, as opposed perhaps to its appearance, in countries that withdraw from that order is likely to be low. This is a sobering thought for those, like me, who believe that this order and central bank independence are valuable, as evidence indeed indicates.29
Fundamentally, central bank independence is valuable because it raises the bar. It makes it harder for the government of the day to pursue short-term objectives at the cost of long-term economic performance and to take decisions for narrow electoral purposes rather than looking after society’s long-term well-being – in short, it makes it more difficult for elected representatives to behave as mere politicians rather than as statesmen. Central bank independence has an option value, just like that of the judiciary or other government agencies.30
This also means that tensions between the government and the central bank should not be seen as a sign that independence has failed. Rather, they are precisely a sign that it is playing the intended role – in finance lingo, that the option is exercised. Recall what the late Tommaso Padoa-Schioppa used to say about the Stability and Growth Pact in Europe: if no one complains, it means the pact is not biting. Today, central bank independence is an option that is very much “in the money”.
Preserving an open, multilateral economic order is a major collective task. At the same time, there are more modest steps that can help safeguard independence.
How to safeguard central bank independence is a sub-question of a more important one: how can central banks be most effective in pursuing society’s longer-term well-being? After all, independence is a means to an end, not an end in itself. It is only worth preserving if it improves economic outcomes. Ultimately, this is the key to gaining and keeping legitimacy in the eyes of the public31 and body politic. Independence is not a natural right; it must be earned day after day.
Hence two implications.
For one, important as they are, pure political economy considerations, based on how central banks go about pursuing their goals, provide only a partial answer. There is no question that transparency and accountability are critical.32 But they cannot be the whole story. From a positive perspective, central banks have taken strides to improve both, but that has not prevented the current wave of inimical sentiment. From a normative one, what central banks do matters at least as much as how they do it.
The importance of the “what” means that any suggestion for how to retain legitimacy requires taking a stand on what a central bank’s best contribution to society’s long-term well-being can be. This, in turn, calls for taking a stand on how the economy works – a thorny and highly controversial issue.
Here, let me offer only some personal suggestions.
I don’t think restricting (again) central bank mandates to price stability at the exclusion of financial stability is a good idea. I fully understand the reasons for the recommendation. Price stability is more easily measurable, and is thus better suited to supporting accountability. Accountability is easier to enforce in the case of a single objective. And if central banks perform only one function, they would be less vulnerable to the charge of being too powerful. But as history indicates, a narrow objective would not spare central banks for being blamed when things go wrong. The argument loses force if we look at it from the perspective of the “what”.
As argued in detail elsewhere, price and financial stability are joined at the hip (Borio (2019)). They are fundamental properties of a smoothly functioning monetary system. They are both ways of safeguarding the value of money, by protecting against default, erosion of purchasing power, or a dysfunctional payments system. Accordingly, central banks have always been key players in safeguarding stability. This was true under the gold standard, when they were the guardians of convertibility. It has been even more so in recent times. Think, in particular, of the lender of last resort function and, in many countries, long-standing prudential responsibilities. If the role of central banks in financial stability is inevitable, it is only appropriate that they should have the instruments to pursue it.
In fact, the core arguments in favour of central bank independence in the context of price stability apply with equal, if not greater, force to financial stability. They apply to the need to take a longer horizon: the lag between the build-up and materialisation of risks is longer than that between excess demand and inflation – because financial cycles are much longer than business cycles (Borio (2014a)). They apply also to the need to resist the political economy pressures to disregard the long term. Much of the population has grown to dislike inflation, but there is hardly any constituency against the inebriating feeling of getting richer during a financial boom.33 In part reflecting these considerations, as well as more targeted pressures when dealing with individual institutions, the principle of independence for prudential authorities is enshrined in the core principles of banking supervision (BCBS (2006)).34
What, then, are the more promising steps to safeguard independence? I would highlight three.
First step: make a clear distinction between crisis prevention and crisis management (Borio (2011)). Independence is essential in crisis prevention, but it is less justifiable in crisis management whenever solvency is at stake, rather than just liquidity. At that point, public money may be needed and central banks will need to work in close coordination with the government. As Charles Goodhart says, “he who pays the piper calls the tune” (Goodhart and Schoenmaker (1995)). It is worth reflecting on how to put in place arrangements along these lines, including ways to insulate the central bank’s balance sheet from losses incurred in crisis management so as to facilitate exit.
Second step: make the price stability objective more flexible. At very low rates, inflation may be less responsive to policy. For instance, empirical evidence indicates that at very low inflation rates relative price changes account for a larger share of aggregate inflation (Reis and Watson (2010)).35 Some of these changes in relative prices may be cyclical, but a large part could also be structural, and hence less amenable to monetary policy. Under such conditions, strict and very precise36 targets could push central banks to adopt ever more ambitious measures and run the risk of exhausting the ammunition to tackle the next recession. The public would then find it harder to understand why a 2% target should be reached regardless of circumstances.37 Indeed, there are signs that public support for attempts to raise inflation above current levels is waning.38 After all, independence aimed to help bring inflation down and keep it under control; credibility is less likely to come into question if inflation is persistently low, even if below agreed objectives.
Furthermore, such a flexible target is desirable in itself for at least two reasons. First, the fear of the zero lower bound may be overestimated. If, as argued, globalisation and technology have played a key role in keeping inflation so low, the impact on output is benign. Indeed, there is considerable historical evidence indicating that price declines have not tended to coincide with weaker output39 – a sign that such supply side factors have been at work. The Great Depression is an exception. The current deep-seated fear of falling prices, regardless of circumstances, is what Raghu Rajan has rightly called “the deflation bogeyman” (Rajan (2015)). In addition, as argued in detail elsewhere, greater flexibility would also allow central banks to better reconcile price stability with financial and hence macroeconomic stability (eg Borio (2014b)). It would make it possible to employ the interest rate lever in combination with macroprudential measures with a clear longer-term orientation.
Third step: above all, reduce the expectations gap between what central banks can deliver and what they are expected to deliver. A more flexible inflation target would obviously help. But the expectations gap goes well beyond central bank’s ability to fine-tune inflation. It is important to ensure that communication makes crystal clear what central banks can and cannot do in the context of output, employment and financial stability.40 And it is equally important to dispel the notion that central banks can be the engine of growth (Carstens (2019)). Sustainable growth requires a balanced mix of policies, not least structural ones. Unless central banks can manage expectations successfully, those expectations can only be disappointed. The credibility, independence and effectiveness of central banks would suffer as a result.
The question of the policy mix brings me to a thorny topical issue, which looms large when considering the possible need for coordination between monetary and fiscal policy: that is, the risk of fiscal dominance. Fiscal dominance de facto deprives monetary policy of its independence, regardless of de jure arrangements, as it tightly constrains what the central bank can do.
The possible need for coordination between monetary and fiscal policy is again in the limelight. A common argument is that, with the monetary room for policy manoeuvre so narrow, the only way to boost output and increase inflation is to ramp up the fiscal firepower by monetising the corresponding deficits. This would work by putting money directly into the hands of the people, especially if coupled with a promise not to tax that money back for a long time. The reasoning is common to a number of proposals, including pure forms of “helicopter money”41 (Turner (2015), Buiter (2014)) and the more constrained proposal by Bartsch et al (2019).
I believe these arguments are analytically dubious and potentially harmful. The resulting policies reach for short-term gains at the expense of potential large long-term losses. Let me explain.
It is well recognised that helicopter money, in its pure form, involves a promise never to tax the money back; so that expenditures are neither debt nor tax-financed.42 What is less recognised is that this would also require central banks to keep interest rates at zero forever (Borio et al (2016)).43 Any surplus cash will find its way into bank reserves. As a result, lifting rates at some point would call either for paying interest on excess reserves – which would be equivalent to debt financing through the consolidated public sector balance sheet – or else imposing a non-remunerated reserve requirement – which is a tax.44 Not only is the prospect unrealistic, it is hardly reassuring.
The Bartsch et al (2019) proposal – a “constrained” version of helicopter money – raises slightly different issues. Here the promise not to tax the money back, and to keep interest rates at zero, lasts only for as long as inflation is below target. But this begs the question of why “monetary financing” is needed in the first place. For the public at large, it makes no difference whether it is the central bank or the government that credits their account: money is money. With interest rates at zero, the government can finance itself as cheaply as the central bank. Moreover, it can do so at a longer maturity than at the overnight or short-term maturities the central bank can apply, locking in the cost.
More broadly, these proposals expose the central bank to critical medium-term risks.
First, low-for-long interest rates create financial stability risks.45 Over time, this threatens to erode the legitimacy of central banks, whether or not financial stability objectives are explicitly part of their mandates or not.
Second, the proposals reinforce the expectation that central banks are more powerful than they really are. There is nothing fundamentally special about money when interest rates are zero; it has no magical power.
Third, the proposals heighten the risk of fiscal dominance.46 Helicopter money would amount to an extreme form of dominance. In this type of “coordination”, the central bank would effectively commit itself to giving up the use of the monetary policy lever for anything but the agreed purpose. In the more constrained version, a quid pro quo could easily emerge. If the government lends the fiscal levers to the central bank under some conditions,47 why should the central bank not lend the monetary policy levers to the fiscal authorities under some others? After all, coordinated policy – fiscal expansion coupled with interest rate cuts – is more effective, at least in the short run. Moreover, one can easily imagine the pressure on the central bank not to raise rates if, during the monetisation phase, government debt has risen substantially – a kind of “debt trap” (Borio (2014a)).48
Let me be clear. I am not saying that in the next downturn fiscal policy should have no special role to play. Nor am I saying that the central bank and the government should refrain from working in a mutually consistent way in their respective spheres of competence. On the contrary, central banks will need a helping hand in countries that still have some room for fiscal policy manoeuvre – although, unfortunately, that room has been narrowing and the number of countries falling. What I am saying is that schemes involving explicit deficit monetisation are unnecessary and potentially harmful. And that fiscal dominance should be avoided.
In the land of Giambattista Vico, the 18th century Neapolitan philosopher-cum-historian, it is fitting to recall his view of history (Vico (1744)).49 It is a view of corsi (courses) and ricorsi (recurrences), with a cyclical rhythm of rise and fall, of resurgence, decadence and barbarism. Without going that far, there are uncanny similarities between the two most recent waves of globalisation, although the compression of time, as if accelerated by the pace of technology, is spellbinding.
Then, as now, a phase of seemingly never-ending prosperity paved the way for a deep slump – the roaring twenties ushered in the Great Depression just as the Great Moderation ushered in the Great Recession. Then, as now, a credit boom that ended badly led to a financial crisis (Eichengreen and Mitchener (2004)). Then, as now, intellectual convictions crumbled along with the economy.
That said, there are differences, too. So far, one full decade on, the open global economy has faltered, yet it has held up. The institutional fabric of society has seen threats, yet it has survived. And central bank independence has come under strain, yet it has endured. There are steps that can be taken to support this valuable institution, as part of the broader task of adjusting policies to promote society’s well-being. The question is whether what we have seen is a temporary setback or a temporary reprieve. Only time will tell.
