Central banking, climate finance, and contemporary crises

Jacqueline Best & Matthew Paterson

In the last few years, as central banks have begun to pay attention to climate change, there has been a flurry of academic interest in what central banks are doing and the potential this might hold for climate change action. Yet the crises of the last three years – COVID-19, the return of inflation, and the Russian invasion of Ukraine – have complicated the picture, leading us to look again at central banks and their potential role in climate governance and policy.

The promise of central banks taking a more active role in climate policy was raised by Mark Carney’s 2015 speech, ‘Breaking the tragedy of the horizon’, given while he was Governor of the Bank of England. Carney argued that central banks needed to become active in climate policy because of the threats climate change poses to financial stability, a core area of central bank responsibility. Given this, he argued that these risks – from the physical impacts of climate change, the reputational risks to banks investing in fossil fuels, and the risks to assets ‘stranded’ by climate change policies leading to decarbonisation – needed to be the focus of banking regulation and macroeconomic management. 

In the following years, many central banks have introduced policies designed to take account of climate risks, introducing climate stress testing into their financial supervision, and creating the Network for Greening the Financial System, a global network of central banks. A handful of central banks have gone further, moving away from market neutrality in their own asset purchases and issuing green bonds to finance climate-friendly investment.

Many commentators have been optimistic about central banks’ new attention to climate change because of the particular power of central banks to regulate financial institutions, as well as their potential to create credit through their balance sheets. Their hope has been that this could be decisive in shifting investment away from fossil fuels and towards decarbonisation. 

But at the same time, it is clear that the over-riding interest of central banks is in financial stability, and thus what has emerged are policies focused on minimising risks of bank failures, through for example stress-testing of banks to climate-related risks. Central banks are inherently conservative institutions, largely unsuited for a more activist role in shaping investment. And when they do, they mostly shape it conservatively, as in enabling fossil fuel assets to flourish in the aftermath of the COVID crisis, and often intensifying existing social inequalities. Perhaps the expectations of central bank climate activism are simply misplaced. Perhaps the most interesting institutional dynamics currently driving climate finance responses are occurring elsewhere—in new forms of ‘state capitalism’, for example, and the recent turn to industrial policy to drive investments in the climate transition. 

Yet this story is itself somewhat limited and certainly Eurocentric. A recurrent theme in our conversations regarded the dangers in this story of focusing too much on Europe and North America. Outside that zone, China has taken the lead in more activist policies, pioneering many policies that have later been adopted and standardized by the EU and other western countries.

What effect might the return of inflation have had on this central bank activity on climate change? In most countries, securing price stability – keeping inflation within certain bounds – is the core responsibility of central banks. The period from the late 1980s and the 2008 global financial crisis is often labelled ‘the Great Moderation’, when macroeconomic conditions were remarkably stable and inflation was low. The rapid return of inflation since early 2021 raises the prospect not only of protracted instability and insecurity, but of distracting central banks from any climate activism they have entertained, worried about drifting too far from their core mandate. 

But the return of inflation also brings with it the potential for a more fundamental rethinking: while some have invoked older explanations of inflation, centred on ‘wage-price spirals’, others like Isabel Schnabel of the ECB have pointed out that it is natural gas prices, both before and especially since the invasion of Ukraine, that are driving inflation across the economy. This ‘fossilflation’ implies that if governments and central banks want to return to stable and low inflation, then accelerating the shift away from fossil fuels is a key means to do this. Even before the rapid rise of natural gas prices from 2021 onwards, solar and wind were cheaper than gas in most places, so shifting to renewables would have significant effects on overall inflation levels.

Which of these framings will prevail among central bankers depends partly on questions of expertise. Which types of experts within central banks shape their overall approaches? How open are they to the new forms of thinking required to take climate change into account? There is evidence that over the last decade central bankers have been more reflexive about the limits of their models and assumptions—perhaps even shifting to a ‘technocratic keynesian’ paradigm. Yet many of their responses to the recent return of inflation have involved a return to orthodox economic thinking. These epistemic conflicts are in a state of flux and how they will play out is unclear.

Central banks traditionally are, at least in Europe and North America, relatively insulated from the day-to-day turbulence of political life. But both the current crises and the demands placed by climate action itself have generated very significant pressures on central bank independence. Banks have been put under considerable pressure by climate activists to shift investments away from fossil fuels, pressures which occasionally reach central bankers as bank regulators. Even some former central bankers openly consider the possibility of abandoning central bank independence, chiding other more conservative ones for regarding this as a catastrophe commensurate with the potential global devastation of unchecked climate change.

Underlying these specific questions are some much bigger systemic questions about the past and present trajectory of global capitalism and its complex historical relationship with climate change: is the global economy at an inflection point in those patterns with the return of inflation, or is it still defined by the problems of stagnation that have defined the years since the 2008 global financial crisis? 

In sum, what our workshop decisively revealed was the indeterminacy of the present moment: while it is possible to trace future paths in which central banks could play a significant and constructive role in climate governance, there are equally many potential paths that would make them significant obstacles to the kind of profound political economic transformations needed to respond to the climate crisis. 

This blog post synthesizes a few of the many excellent ideas articulated by workshop participants, including: Ilias Alami, Dan Bailey, Sarah Bracking, Jeremy Green, Eric Helleiner, James Jackson, Paul Langley, Sylvain Maechler, John Morris, Stine Quorning, Adrienne Roberts, Jens Van’t Klooster, Robbie Watt, and Stan Wilshire.

Why we need better central bank accountability

As pundits debate whether the US Federal Reserve will raise interest rates again this summer or fall, we are reminded of just how much of the economy’s direction hinges on central bankers’ decisions.

Since the 2008 financial crisis, the power of central banks has grown, as they have used unorthodox tools to stimulate the economy, taken a greater role in financial regulation, and put themselves in more politically sensitive positions, including the tough debt negotiations with Greece.

In spite of this powerful role, central bankers are remarkably insulated from democratic oversight. As a recent “Buttonwood” column notes in The Economist, “Janet Yellen and Mario Draghi are very important players in the world economy, arguably more important than the US President or the German chancellor. And yet they are not elected; if voters do not like the job they are doing, they cannot get rid of them.”

There is a great deal at stake in decisions about monetary policy, as I suggest in a recently published article in Ethics & International Affairs. Central banks not only define the broad direction of the economy but also create winners and losers. Consider, for instance, the disparate reactions of a prospective first-time home buyer and a retired couple living on their savings to the prospect of yet another drop (or increase) in the interest rate.

Central bank independence in its current form is relatively recent. Elected leaders exercised considerable influence over monetary policy in the post-war era, seeking to achieve the right “trade-off” between full employment and inflation. It was only in the 1980s that policymakers moved away from this kind of Keynesianism and embraced the ideas of Milton Friedman, who advocated the creation of an independent monetary authority.

Friedman and other economists believed that if governments were given any discretion over monetary policy they would adopt inflationary policies because these were more likely to be popular with the electorate. They argued that the only way to ensure price stability was to radically limit the government’s influence over monetary policy by making central banks autonomous and requiring them to stick to a simple rule, such as an inflation target. By the late 1990s, central banks in over thirty countries had gone down this path and were using some form of inflation targeting.

The current model of central bank governance does provide for a certain kind of accountability—but only a very narrow one. Ensuring accountability generally involves three elements: broadly-agreed upon standards, information on whether they are met, and sanctions if they are not. Because the principle of central bank independence involves a very limited set of standards—specifically, the achievement of an inflation target—and very few opportunities for sanction, the main mechanism for accountability is provided by publishing information about the bank’s activities. Hence we have seen the rapid expansion of central banks’ commitment to providing more and better information about their models and decisions in recent years.

Unfortunately, while this informational form of accountability may have worked during the stable years of the “Great Moderation” (from the mid-1980s to the 2008 crisis), it is no longer up to the task in the volatile post-crisis era.

Bank of Canada Governor Stephen Poloz and US Federal Reserve Chair Janet Yellen have both suggested that growing economic uncertainty has reduced the effectiveness of simple models and rules. What these bank governors have not acknowledged (unsurprisingly) is the challenges that this growing uncertainty poses for existing forms of accountability.

If uncertainty limits the effectiveness of rule-based policy, then it ultimately requires greater discretion on the part of policymakers. This is not a problem in itself (here I would disagree with those Republican lawmakers who would bind the Fed even further with more stringent rules). More discretion does, however, require a more robust form of accountability.

There are three basic principles that should underpin any such reforms.

1) Fostering more deliberation and dissent

While the informational model of accountability obligates decision-makers to explain their actions, it reduces this process to a simple publication of data. What is missing is the back and forth of question and answer—the process of genuine debate and deliberation. By the mid-2000s, central bankers were being treated like oracles, with Alan Greenspan as the most revered among them. There must be more room for dissent—both among those with the power to set monetary policy and in the wider society that is affected by those policies.

2) Ensuring that central banks are answerable to the wider public

Because financial issues are complex and their impacts are often diffuse, monetary policy questions rarely become salient enough to mobilize public action. In this context, the power of sanction actually shifts away from the two groups to whom central bankers should be accountable—the government and the public—and toward financial actors, who can impose very serious sanctions on central banks if they disagree with their policies. Without overly politicizing monetary policy, we need to find creative ways of ensuring that central banks are more accountable to the wider public.

3) Broadening the objectives against which their actions are judged

One way of ensuring that monetary policymakers are accountable to the public is to ensure that the issues that affect citizens are reflected in the standards that guide bank policy. At present, most of these issues are not officially on the agenda, which is constrained by the goal of achieving a very low level of inflation.

A number of commentators have recognized this dilemma and have suggested that today’s inflation targets may no longer be appropriate. A recent Federal Reserve working paper suggests that increasing the current inflation target and supplementing it with a nominal GDP target makes economic sense. Such moves to broaden the objectives used to guide central bank decisions would also go some way toward increasing their accountability.

As central banks take on an increasingly powerful role in our political and economic lives, it is time to find new ways of ensuring that they are more fully accountable.

Central banks are facing a credibility trap

Quite a few commentators have noted that central bankers have become rather less boring of late. Since the 2008 financial crisis, central banks have taken on new roles and responsibilities. They have experimented with a whole range of unconventional monetary policies. And, in the process, they have gained considerably in power and influence.

There has been less attention to a key paradox underlying central bankers’ new roles on the world stage: they are being forced to govern through exceptions in an era in which rule-following (particularly the holy grail of the 2% inflation target) has become the ultimate source of policy credibility. Where central bankers are supposed to stick to the rules, they have found themselves endlessly making exceptions, promising that one day things will return to normal.

This paradox poses real challenges for efforts to foster a sustained global economic recovery. Governing through exceptional policies is always a politically-fraught undertaking, particularly over the long-term, but it is even more difficult in a context in which the dominant convention is one of strict rule-following.

Since the early experiments with monetarism in the late 1970s and early 1980s, most central banks have moved towards an increasingly rule-based approach to monetary policy, with inflation targeting becoming the norm in many countries in recent years.

Yet today we are faced with a situation in which the rules no longer apply but are still being invoked as if they did.

A recent Buttonwood column notes that the Bank of England has missed its inflation target “almost exactly half the time” since 2008. The European Central Bank (ECB) has effectively expanded its narrow mandate, which formally requires it to make price stability its top priority, by arguing that employment and other issues are crucial to achieving it. Yet the ECB and the Bank of England continue to act as if the old rules still apply.

If we look beyond the narrow rules that are supposed to be governing central bank actions and examine the wider changes in their recent policies, we find similar patterns. Scratch an unconventional monetary policy and you will find a kind of economic exceptionalism: an argument that the crisis that we face is extreme enough that it requires a radical but temporary suspension of economic rules and norms.

Most of the unconventional monetary policies that have been tried to date, and just about all of those that have been proposed as future possibilities if we face a renewed global recession, break quite radically with existing norms. Negative interest rates weren’t even supposed to be economically possible (until they were tried), while quantitative easing (a central bank’s buying up bonds by massively increasing the size of its balance sheet) still carries a whiff of irresponsibility linked to its past as a way for governments to avoid fiscal retrenchment by “printing money.”

More recent proposals include helicoptering money into the government’s or the public’s accounts, abolishing cash to make low interest rates effective, and even introducing a reverse incomes policy—a government-enforced increase in wages (as opposed to the wage controls of the 1970s) to try to get inflation going.

All of these existing and potential policies break with current economic norms, and all are being pitched as temporary, exceptional measures that are (or may be) necessary in the face of an extreme crisis.

Ironically, rule-following was designed precisely to avoid this problem. It came into its own as an influential approach to monetary policy in the wake of the destabilizing 1970s, with their stop-go economic policies and rampant inflation. Mainstream economists came to love rule-based monetary policy as did politicians—not just neoconservatives like Margaret Thatcher and Ronald Reagan who first championed the approach, but eventually the more centrist politicians who followed like Tony Blair and Bill Clinton, as well as today’s mixed lot.

A rule-governed approach to policy was designed to be both politically and economically stabilizing—to do away with the problem and even the possibility of exceptions by removing not only governments’ but even central bankers’ discretion: just stick to the rule, and everything will work out. A tidy, efficient, depoliticized (although certainly not apolitical) approach to monetary policy.

Yet rules only seem great until they don’t apply anymore. A rule that pretends it can always apply (or at least, as Colin Hay puts it in his introductory blog, in the 99.9% of times that seem relevant) inevitably runs serious problems when an exception becomes necessary.

Of course, as Alan Greenspan has noted, the victory of rules over discretion was never entirely true in practice. But it was an extremely powerful narrative—one that promised that central banks’ (and governments’) commitments to low inflation and economic stability was credible because they were constrained to follow the rules.

It was also a very effective narrative that has convinced markets that anything other that rule-following is likely to be destabilizing. As central banks begin to face the limits of those rules, their earlier persuasiveness has come back to haunt them: a recent paper from some Federal Reserve staff notes that although a higher inflation target would make sense in the United States, increasing it could well backfire if market actors believed that it would be too inflationary.

This fixation on rule-following has thus put central bankers into a credibility trap. If bankers admit that the rules no longer apply, then they risk losing their credibility as market actors have come to believe the mantra that rules—particularly low inflation targets—are the only way to ensure sound monetary policy. On the other hand if they don’t admit the limits of the rules, and continue lurching from exception to exception, they will eventually lose credibility as the gap between rhetoric and reality widens.

Central banks are damned if they do admit the limits of rules and damned if they don’t.

Of course, the most viable solution to this trap is for governments to stop relying so heavily on central banks in the first place and start taking some responsibility for economic recovery through concerted fiscal action (something that the Canadian government has at least started to do). Yet for that kind of fiscal action to work, governments have to convince the markets that they believe in it enough to stick to their guns and follow through—a rather unlikely scenario in today’s austerity-driven times.

As the potential for renewed economic crisis continues to grow, this credibility gap will only widen—as central bankers and governments find themselves lurching from exception to exception, refusing to question the neoliberal rules that no longer seem to apply.

Canada needs to do a better job of managing financial uncertainty

Published in the Hill Times, May 25, 2015

As Canadians, we pride ourselves on how well our financial regulations coped with the 2008 financial crisis. Given this attitude, it’s not surprising that Canadian policymakers have avoided a major overhaul to our regulations in response.

Yet we need to make sure that this pride in our system does not lead to complacency. Rather than just looking backwards to how the Canadian financial system performed in the last crisis, we also need to look forwards and recognize how much the global economy is changing.

Those changes take two key forms. First, the economy has become much more uncertain since the crisis. And second, a number of other countries have raised the bar for financial regulation. If Canadians don’t catch up with these two major shifts, we may well find ourselves in trouble.

Whether we look at the International Monetary Fund’s latest Global Financial Stability Report, or the Bank of Canada’s recent Financial System Review, it is clear that both the global and national economies have become increasingly uncertain. That uncertainty defines some of the most important aspects of our economy, whether we look at the likely medium-term impact of the decline in oil prices, the potential for a hard landing in an overheated housing market, or the possibility that Canadians will wake up one day and realize that their household debt level is unsustainable.

This environment of profound uncertainty poses serious policy challenges.

In the good old days of the so-called “Great Moderation” from the mid-1980s to the financial crisis, policymakers were able to focus on what Donald Rumsfeld famously described as “known unknowns”—the kinds of risks to which policymakers could assign definite probabilities. Today, we are faced instead with a great deal of “unknown unknowns”—the kinds of uncertainty that resists formal modeling, as Bank of Canada Governor, Stephen Poloz noted in a recent paper.

How should we regulate financial markets in the face of this kind of uncertainty? Very carefully. As it becomes increasingly difficult to predict what kinds of complex risks the economy might face, we need to err on the side of caution.

As good Canadians we might assume that we already have some of the most cautious financial regulations around. Yet this is no longer the case.

Yes, Canada has implemented the capital adequacy standards set out in the Basel III accord very quickly. Yet our government has treated those requirements as the gold standard, when they were designed to be a bare minimum. On the other hand, the United Kingdom and the United States are in the process of implementing more demanding standards, including adopting higher and stricter leverage ratios. While Canada was one of the only countries with a leverage ratio requirement before the crisis, we now starting to look relatively lax.

Even more striking is the fact that Canada, unlike every other major country, has no central body responsible for coordinating efforts to manage systemic risk. The Canadian regulatory universe is fragmented, with important pieces of the regulatory puzzle managed by half a dozen agencies plus a multitude of provincial authorities. The Bank of Canada does an admirable job of identifying potential sources of systemic risk, but they have few tools for acting on them.

Canadian authorities have engaged in macroprudential regulation in recent years—most notably through their efforts to cool the housing market down. Yet, as a recent IMF report points out, those efforts have unintentionally encouraged those who no longer qualify for prime mortgages into the under-regulated world of “shadow lending,” potentially increasing systemic risk. In order to manage an uncertain economy, someone needs to be able to look at the system as a whole: to connect the dots that link regulations governing consumer credit, mortgages, interest rates, big, small and “shadow” banking institutions.

What about the usual financial sector response that more regulation will cost Canadian financial institutions, and thus the economy, more generally? We should have learned by now that the cost of another crisis would be much greater still. Given the triple threat of uncertain oil prices, a volatile housing market and rising consumer debt, another crisis would likely hit us harder than the last one. It’s worth being well prepared for that kind of risk.

Why we need to take economic uncertainty seriously

If you have been reading the financial press over the past week, you know that the global economy’s chances are looking a lot more uncertain these days. What you may not know, however, is that this more recent upswing in uncertainty and volatility is part of a much broader pattern in the global economy—one that poses some real challenges for how policymakers do their job.

Stephen Poloz, the Governor of the Bank of Canada, just released a working paper in which he suggests that the economic climate has become so profoundly uncertain since the global financial crisis of 2007-2008 that it resists formal modeling.

Because of this, the Bank will no longer engage in the policy of ‘forward guidance’, in which it provides markets with a clear long-term commitment to its current very low interest rate policy. The Bank is changing this policy not because it is any less committed to low interest rates in the medium term, but because it does not want to give the markets a false sense of security about the predictability of the future. Instead, Poloz suggests that policymakers should do a better job of communicating the uncertainties facing the economy and the Bank itself as it formulates its policies.

Why should we care about this seemingly minor change in the Bank of Canada’s policy? Because it underlines just how much our governance practices are going to have to change in order to cope with the increasing uncertainty of the current economic and political dynamics.

It’s ironic that this warning is coming from the Bank of Canada. Central banks do not like change. They are just about the most conservative government institutions around.

Since the late 1970s, central bankers have been wedded to the idea that the most straightforward monetary policies are the best—ideally taking the form of a simple rule that can be expressed as a quantitative target, like the Bank of Canada’s inflation target. Economists argue that such policy rules are stabilizing because they avoid giving too much discretion to central bankers, thus reducing uncertainty about the Bank’s plans and increasing the credibility of their commitment to low inflation.

Yet these simple rules are effective only as long as the models that they are based on can accurately capture an economy’s dynamics and needs. If the economy is too complex and uncertain for such straightforward forms of quantification, then simple rules are at best misleading, and at worst destabilizing.

Poloz’s recent paper suggests that he recognizes some of these dilemmas—and the importance of coming to terms with them quickly in the current period of economic volatility.

The Bank of Canada’s Governor is not alone in recognizing these uncertainties. Janet Yellen, the current Chair of the United States Federal Reserve Board, has also pointed to the limits of simple rules in guiding central bank policy in the current context. Her predecessor, Ben Bernanke, referenced Donald Rumsfeld’s concept of ‘unknown unknowns’ to describe the extreme uncertainty that faced market participants during the recent financial crisis.

Yet, with this paper, Poloz seems to go further than his American counterparts in recognizing the implications of these unknown unknowns. In the same speech cited above, Bernanke argued that the failures of the global financial crisis were failures of engineering and management, and not of the underlying science of economics.

Poloz, by contrast, describes the work of monetary policymaking as a “craft” (not a science), and suggests that it is too complex to be treated as a form of engineering. The uncertainty that we are dealing with today, he suggests, “simply does not lend itself as easily to either mathematical or empirical analysis, or any real sort of formalization.”

This is a remarkable departure from the kind of numbers-driven rhetoric that we have heard from the Harper government in recent years.

The Canadian government has been increasingly preoccupied with measuring results, in health careinternational development, and across government-funded programs. Last May, when announcing additional funds for the health of mothers and children in developing countries, Stephen Harper argued, “You can’t manage what you can’t measure.

Poloz’s paper suggests that, on the contrary, because of the sheer complexity and uncertainty of the current global order, we have no alternative but to find ways of managing what we can’t measure. As I argue in my recent book, rather than using ever-more dubious indicators and targets to drive policy on everything from health to the economy, we need to find better ways of assessing, communicating and managing the true complexity of the policy challenges that we face.

This will not be an easy task, either technically or politically. It will take time to educate a public—not to mention a market—that has become used to simplified pronouncements.

The less we can rely on objective measurements and simple rules, the more careful we have to be about ensuring democratic accountability for policy decisions—through the political process and through an informed and active media.

And perhaps the biggest challenge that this new reality presents is the need for our politicians to heed Poloz’s suggestion that they not only recognize the inescapability of “uncertainty, and the policy errors it can foster,” but that they wear them “like an ill-fitting suit . . . that is, with humility.”

Humility tends to be in scarce supply in political circles these days. That too will need to change if we’re going to develop the kinds of creative policy tools that we need to manage the uncertain times to come.
