The Role of Profits in Banking Regulation

Since the nineties, crises have punctuated financial markets, shattering the conventional wisdom about how these markets work and how to regulate them, and forcing a deep rethinking of the supervisory framework that, however, did not change much of the banks’ behavior and incentives. In particular, banking regulation did not face the nexus profitability-riskiness. Based on Minsky’s financial instability hypothesis, we discuss the literature on banks’ profitability and its relation to the originate-to-distribute model. We also propose a different strategy for banking regulation, based on a profitability cap that prevents financial innovation from overwhelming supervision. Finally, we discuss the data for the US case, confirming the importance of profitability as a signal of incoming troubles and the possibility of using the profitability cap to greatly simplify banking regulation.

This paper provides an empirical analysis of nonfinancial corporate debt in six large Latin American countries (Argentina, Brazil, Chile, Colombia, Mexico, and Peru), distinguishing between bond-issuing and non-bond-issuing firms, and assessing the debt’s macroeconomic implications. The paper uses a sample of 2,241 firms listed on the stock markets of their respective countries, comprising 34 sectors of economic activity for the period 2009–16. On the basis of liquidity, leverage, and profitability indicators, it shows that bond-issuing firms are in a worse financial position relative to non-bond-issuing firms. Using Minsky’s hedge/speculative/Ponzi taxonomy for financial fragility, we argue that there is a larger share of firms that are in a speculative or Ponzi position relative to the hedge category. Also, the share of hedge bond-issuing firms declines over time. Finally, the paper presents the results of estimating a nonlinear threshold econometric model, which demonstrates that beyond a leverage threshold, firms’ investment contracts while they increase their liquidity positions. This has important macroeconomic implications, since the listed and, in particular, bond-issuing firms (which tend to operate under high leverage levels) represent a significant share of assets and investment. This finding could account, in part, for the retrenchment in investment that the sample of countries included in the paper have experienced in the period under study and highlights the need to incorporate the international bond market in analyses of monetary transmission mechanisms.

A Global Cap to Build an Effective Postcrisis Banking Supervision Framework

The global financial crisis shattered the conventional wisdom about how financial markets work and how to regulate them. Authorities intervened to stop the panic—short-term pragmatism that spoke volumes about the robustness of mainstream economics. However, their very success in taming the collapse reduced efforts to radically change the “big bank” business model and lessened the possibility of serious banking reform—meaning that a strong and possibly even bigger financial crisis is inevitable in the future. We think an overall alternative is needed and at hand: Minsky’s theories on investment, financial stability, the growing weight of the financial sector, and the role of the state. Building on this legacy, it is possible to analyze which aspects of the post-2008 reforms actually work. In this respect, we argue that the only effective solution is to impose a global cap on the absolute size of banks.

Policy Challenges for Central Banks

Central banks responded with exceptional liquidity support during the financial crisis to prevent a systemic meltdown. They broadened their tool kit and extended liquidity support to nonbanks and key financial markets. Many want central banks to embrace this expanded role as “market maker of last resort” going forward. This would provide a liquidity backstop for systemically important markets and the shadow banking system that is deeply integrated with these markets. But how much liquidity support can central banks provide to the shadow banking system without risking their balance sheets? I discuss the expanding role of the shadow banking sector and the key drivers behind its growing importance. There are close parallels between the growth of shadow banking before the recent financial crisis and earlier financial crises, with rapid growth in near monies as a common feature. This ebb and flow of shadow-banking-type liabilities are indeed an ingrained part of our advanced financial system. We need to reflect and consider whether official sector liquidity should be mobilized to stem a future breakdown in private shadow banking markets. Central banks should be especially concerned about providing liquidity support to financial markets without any form of structural reform. It would indeed be ironic if central banks were to declare victory in the fight against too-big-to-fail institutions, just to end up bankrolling too-big-to-fail financial markets.

A Reply to Critics

One of the main contributions of Modern Money Theory (MMT) has been to explain why monetarily sovereign governments have a very flexible policy space that is unencumbered by hard financial constraints. Through a detailed analysis of the institutions and practices surrounding the fiscal and monetary operations of the treasury and central bank of many nations, MMT has provided institutional and theoretical insights about the inner workings of economies with monetarily sovereign and nonsovereign governments. MMT has also provided policy insights with respect to financial stability, price stability, and full employment. As one may expect, several authors have been quite critical of MMT. Critiques of MMT can be grouped into five categories: views about the origins of money and the role of taxes in the acceptance of government currency, views about fiscal policy, views about monetary policy, the relevance of MMT conclusions for developing economies, and the validity of the policy recommendations of MMT. This paper addresses the critiques raised using the circuit approach and national accounting identities, and by progressively adding additional economic sectors.

A Reinterpretation of Henry Simons’s “Rules versus Authorities in Monetary Policy"

Henry Simons’s 1936 article “Rules versus Authorities in Monetary Policy” is a classical reference in the literature on central bank independence and rule-based policy. A closer reading of the article reveals a more nuanced policy prescription, with significant emphasis on the need to control short-term borrowing; bank credit is seen as highly unstable, and price level controls, in Simons’s view, are not be possible without limiting banks’ ability to create money by extending loans. These elements of Simons’s theory of money form the basis for Hyman P. Minsky’s financial instability hypothesis. This should not come as a surprise, as Simons was Minsky’s teacher at the University of Chicago in the late 1930s. I review the similarities between their theories of financial instability and the relevance of their work for the current discussion of macroprudential tools and the conduct of monetary policy. According to Minsky and Simons, control of finance is a prerequisite for successful monetary policy and economic stabilization.

How to Achieve a Better Balance between Global and Official Liquidity

Global liquidity provision is highly procyclical. The recent financial crisis has resulted in a flight to safety, with severe strains in key funding markets leading central banks to employ highly unconventional policies to avoid a systemic meltdown. Bagehot’s advice to “lend freely at high rates against good collateral” has been stretched to the limit in order to meet the liquidity needs of dysfunctional financial markets. As the eligibility criteria for central bank borrowing have been tweaked, it is legitimate to ask, How elastic should the supply of central bank currency be?

Even when the central bank has the ability to create abundant official liquidity, there should be some limits to its support for the financial sector. Traditionally, the misuse of the fiat money privilege has been limited by self-imposed rules that central bank loans must be fully backed by gold or collateralized in some other way. But since the onset of the crisis, we have seen how this constraint has been relaxed to accommodate the demand for market support. My suggestion is that there has to be some upper limit, and that we should work hard to find guidelines and policies that can limit the need for central bank liquidity support in future crises.

In this paper, I review the recent expansion of central bank liquidity support during the crisis, before discussing the collateral polices related to central banks’ lender-of-last-resort and market-maker-of-last-resort policies and their rationale. I then examine the relationship between the central bank and the treasury, and the potential threat to central bank independence if they venture into too much risky balance sheet expansion. A discussion about the exceptional growth of the shadow banking system follows. I introduce the concept of “liquidity illusion” to describe the fragility upon which much of the sector is based, and note that market growth has been based largely on a “fair-weather” view that central banks will support the market on rainy days. I argue that we need a better theoretical framework to understand the growth in the shadow banking system and the role of central banks in providing liquidity in a crisis.

Recently, the concept of “endogenous finance” has been used to explain the strong procyclical tendencies of the global financial system. I show that this concept was central to Hyman P. Minsky’s theory of financial instability, and suggest that his insights should be integrated into the ongoing search for a better theoretical framework for understanding the growth of the shadow banking system and how we can limit official liquidity support for this system. I end the paper with a summary and a discussion of some of the policy issues. I note that the Basel III “package” will hopefully reduce the need for central bank liquidity support in the future, but suggest that further structural reforms of the financial sector are needed to ease the tension between freewheeling private credit expansion and the limited ability or willingness of central banks to provide unlimited official liquidity support in a future crisis.

This paper explores the significance of Islamic banking in Malaysia for stability in the country’s economy as a whole. Neither conventional theory nor Islamic economics puts forward a systematic explanation of financial intermediation; consequently, neither is capable of identifying destabilizing elements in the system. Instead, a flow-of-funds approach similar to Minsky’s own is applied to the (post-) modern (consumption-led) business cycle and financial (and asset) market.

Malaysia’s structural current account surplus contributes to the overcapitalization of domestic firms. This in turn finances a financial (as opposed to an industrial), consumption-led (instead of investment-led) business cycle, where banking favors destabilizing asset price inflation. Islamic banks operating interdependently with conventional ones contribute to economic destabilization, channelling surplus funds from the corporate to the household sector.
