Populism and Central Bank Independence


JEL-Codes: D72, D78, E31, E52, E58, E62.
Keywords: Populism, central bank independence, financial inequality,  monetary policy, banking policy, political economy.

The populist narrative hinges on the feeling of frustration with the current Situation. This SUERF Policy Note focuses on financial inequality, populism and central bank independence, shedding light on the relationships between aggrievement in the electorate and large financial inequality, the advancement of populist parties and the risk that myopic policies are going to be adopted. In such a situation a populist policy that promotes a politically controlled central bank – that is perceived as a technocratic elite -   it is more likely to occur.


Is the Populism Wave going to hit the Central Bank Independence Rock?

Several scholars have recently argued that the rise of populism can dent the consensus that underpinned the support for central bank independence (CBI) from the late 1980s until the 2008 Financial Crisis (e.g. Buiter 2016, de Haan and Eijffinger 2017, Goodhart and Lastra 2017, Rajan 2017). The aim of this note is to pin down the possible relationship between financial inequality of the electorate, preferences for populism and CBI. Our argument will use a political economy framework.

In a nutshell, our main point is the following: Populist voters share common feelings of frustration with the current economic situation. It fuels the desire to punish the elite, which is blamed for unequal and unjust outcomes. Populist leaders propose anti-system policies, in which the people gain full control over fiscal and monetary policies. Such policies myopically underestimate the negative consequences of reducing central bank independence for the stability of the financial system. They are more likely to emerge when there is large diversity in voters’ portfolios (financial inequality). The reason is that a larger share of the electorate feels frustrated with the current situation. Consequently, they are more inclined to prefer populist platforms. Moreover, fiscal and monetary policies have stronger redistributive consequences, fuelling the conflict within society.
 
After a first wave of populism that was mostly concentrated in Latin America (Dornbush and Edwards 1991, Acemoglu et al. 2013) a second wave of populism gained ground in several European countries and in the United States. In Europe, anti-system sentiments are ubiquitous to populist narrative on both sides of the left-right wing spectrum. Such movements have already directly and/or indirectly influenced economic policies in these countries and will continue to do so in the future (Dovis et al. 2016, Aggeborn and Persson 2017, Rodrik 2017).

Populist movements seem to have in common a demand for short term protection, and a certain degree of myopia as for the future consequences of their current policies (Guiso et al. 2017). Populist leaders present solutions which are welfare enhancing in the short run for a majority of the population, but costly in the long run for the whole population (Sachs 1989, Dornbush and Edwards 1991, Acemoglu et al. 2013, Chersterley and Roberti 2016).

Now “with their PhDs, exclusive jargon, and secretive meetings in far-flung places like Basel and Jackson Hole, central bankers are the quintessential rootless global elite that populist nationalist love to hate” (Rajan 2017). In other words, if the notion of central bankers  provides a natural target for populist policies, the research question that naturally arises is the following: what are the conditions under which a populist reform – i.e. a reform that is aimed to guarantee short term protection disregarding longer term consequences – is likely to occur? When is the pillar of the central banks’ power - i.e. its independence – more likely to be undermined? 

Before the Financial Crisis, the independence of central banks was unquestioned.  It had become the benchmark to evaluate the effectiveness of the monetary institutions all around the world, and a broad consensus supported such institutional design (Cecchetti 2013, Bayoumi et al. 2014, Goodhart and Lastra 2017, Issing 2018). After the Financial Crisis, CBI has become again a relevant subject in academia (Figure 1), as well as in politics and in the media. Several scholars   (Alesina and Stella 2010, Cecchetti 2013, Bayoumi et al. 2014,  Issing 2018) have emphasized that critical voices against CBI seem to dominate (Stiglitz 2013, Ball et. Al 2016, Rodrik 2018).

The reason is mainly that the economic and political importance of central banks in advanced economies has – with good reason - grown since the beginning of the Financial Crisis (Buiter 2014). Supervisory and regulatory functions have piled up at central banks, increasing the links between banking sector, fiscal and monetary policies (Bayoumi et al. 2014, de Haan and Eijffinger 2017). The borders between the central bank’s role as liquidity manager and the government’s solvency support for banking and financial institutions have been blurred, triggering a new debate on central bank competences and design (Nier 2009, Bean 2011, Cecchetti et al. 2011,  Ingves 2011,  Reis 2013; for an historical perspective, see Bordo and Siklos 2017; on the features of the CBI, see Cukierman 2008 and 2013, Cecchetti 2013, Taylor 2013, Buiter 2014, Sims 2016,  Blinder  et al. 2017). Against this background an important question is whether the policy blurring effect has made the pendulum swing, triggering a reduction in CBI around the world; so far comparative analyses did not reach homogenous results (Bodea and Hicks 2015, Masciandaro and Romelli 2018).


The Wave and the Rock: Financial Inequality, Populist Policies and the Role of the Central Bank as Veto Player


A recent paper by Masciandaro and Passarelli (2018) argues that a possible channel of the relationship between populism and CBI is financial inequality. The paper considers an economy where a systemic banking shock can occur and the policymakers can design a policy - which involves banking, fiscal and monetary aspects - in order to minimize the spillovers over the real sector. These policies affect the independence of the central bank.

The economy consists of a population of citizens, a government, a central bank and a banking system. The sequence of events is the following (Figure 2 below). At   banks implement risky businesses (normal times). The outcome of such activities determines how safe and sound the bank is, i.e. the bank’s capacity to meet its obligations. At   a bank failure possibly occurs. It triggers negative externalities that can spread over to the economy. The government has to design a strategy to curb such externalities (extraordinary times). The public policy is three-dimensional: banking policy, fiscal policy, and monetization. The banking policy consists in the amount of fresh capital to inject in the bank to prevent failure. The fiscal policy consists in financing the bailout, at least partially, through taxation, which can be distortionary. The cost is passed to the tax-payer. For the remaining part, the government issues debt. Government bonds can be purchased either by citizens or by the central bank. The degree of central bank independence (CBI) shows the central bank’s capacity to act as a veto player against the political pressures to use the monetary policy tools to fix banking problems.

Figure 2: The Business Cycle: Normal Times, Extraordinary Times and the New Normal

 

At  t = 2 government charges an income tax to repay the debt plus interest. Citizens, given the tax, decide how much to work. This is when taxation may cause distortions. The central bank rebates back to the government the payments for interest received on the share of debt that has been monetized (thus we come back to“new” normal times). Higher monetization yields lower price stability at time 2. This is why having a weak central bank, which monetizes a lot, can be socially costly.

A farsighted government will implement the socially optimal three-dimensional policy. It will take into account the intertemporal trade-off between minimizing tax distortions, curbing banking externalities, and reducing price-instability. However, such policy is likely to have heterogeneous effects on citizens’ portfolios. Different individuals will have different views regarding the policy. The policy outcome is unlikely to be the socially optimal one, while it is likely to be politically distorted.

The theoretical argument hinges on the heterogeneity among citizens in terms of financial inequality, provided the mix between banking and monetary policies can produce the so called 3 Ds effects (Goodhart and Lastra 2017): the Distributional Effect occurs as a result of changes in interest rates; the Directional Effect captures the impact of the public policy on some particular sector and/or constituency of the economy such as the banking industry (Brunnermeir and Sannikov 2013; the Duration Effect measures the monetary policy effect on overall public sector liabilities, including the central bank balance sheet: more fiscal monetization reduces the duration of the state balance sheet and is likely to be associated with monetary instability.

The Duration Effect is associated with the dimension and the risk profile of the central bank balance sheet (CBBS). Recently, several authors have emphasized the relevance of CBBS for monetary policy (Curdia 2011, Bindsell 2016, Reis 2016a and 2016b). An abnormal CBBS can trigger instability in a longer horizon for at least two reasons (Rajan 2017), notwithstanding the gains that the provision of a public safe asset can produce (Greenwood et al 2016). The Directional Effect depends on the banking policy choices, while both the Distributional Effect and the Duration Effect are associated with the corresponding fiscal and monetary policies.

Which type of policy do populist voters prefer? Based on the definition of populist platforms given by Guiso et al. (2017), we assume populist voters are myopic regarding the long-term consequences of the three-dimensional policy described above. They tend to prefer policies that provide short-term protection for bank stakeholders with no fiscal burden on the tax-payers’ shoulders. Banks should be put under the government’s control, in order to prevent elites from extending their power over the banking system. Despite populist platforms being usually silent regarding central banks, such a policy points at two likely long-term consequences: the reduction of central bank independence, and monetization of debt issued to save troubled banks.

The populist narrative emphasizes the idea that the general will should prevail. Thus liberal institutions are less useful (e.g. the separation of powers, checks and balances, the representative democracy, and intermediate state institutions). CBI is one of those institutions. It ensures neutrality and the inter-temporal consistency of monetary policy. Curbing the independence of central banks would be consistent with the populist goal of exerting direct control over conflicts within society (Goodhart and Lastra 2017).

The standard rationale for having an independent central bank can be summarized as followed (Fischer 2015): CBI is an institutional device to avoid a distortionary inflation tax. It represents a credible obstacle against political pressure to boost real output through time inconsistent policies (Kydland and Prescott 1977). In standard political economy models, the source of political distortion (and time inconsistency) is income inequality and unemployment. When it comes to banking policy, the source of political distortion is financial inequality. The latter fuels frustration with the elite, and general anti-system sentiments.
  
Higher financial inequality and stronger feelings of aggrievement in the electorate may lead to the adoption of myopic policies. The fiscal costs of extending public control over the banking system is either partially by-passed to future generations through public debt, or minimized through monetization. This kind of policy requires a low degree of CBI to be implemented.
