Debt causes fragility. When banks lack equity funding, even a small adverse shock can put the financial system at risk. Fire sales can undermine the supply of credit to healthy firms, precipitating a decline in economic activity. The failure of key institutions can threaten the payments system. Authorities naturally respond by increasing required levels of equity finance, ensuring that intermediaries can weather severe conditions without damaging others.
Readers of this blog know that we are strong supporters of higher capital requirements: if forced to pick a number, we might choose a leverage ratio requirement in the range of 15% of total exposure (see here), roughly twice recent levels for the largest U.S. banks. But as socially desirable as high levels of equity finance might be, the fact is that they are privately costly. As a result, rather than limit threats to the financial system, higher capital requirements for banks have the potential to shift risky activities beyond the regulatory perimeter into non-bank intermediaries (see, for example here).
Has the increase of capital requirements since the financial crisis pushed risk-taking beyond the regulated banking system? So far, the answer is no. However, in some jurisdictions, especially the United States, the framework for containing systemic risk arising from non-bank financial institutions remains inadequate…. Read More
Prior to the financial crisis, even an informed observer might have naïvely believed that the CEOs of big financial firms could simply push a button to view the current exposure of their firms to any other firms in the world. Or, if less technologically advanced, they could call their chief risk officers or chief financial officers to obtain end-of-day positions.
Not even close. By the time that Lehman failed in September 2008, large financial holding companies had evolved into extremely complex structures with hundreds or thousands of subsidiaries for which the parent companies lacked consolidated information technology and risk-management systems. The multiplicity of information systems meant that different parts of the same firm employed varying names and codes to identify the same counterparty. Fixing this, merging all of the information structures and ensuring consistency, would have been an expensive proposition that managers (compensated out of current profits) had incentive to delay.
Correcting these deficiencies in the financial infrastructure is not a trivial matter. Simplifying the problem requires the creation of a unique, universal, and permanent identification system for both institutions (financial and nonfinancial) and instruments. Realizing the nature of the opportunity and the challenge, in November 2011, the G20 called for the creation of a global legal entity identifier (LEI). Importantly, everyone realized that given the massive size of the financial system that supports both domestic and cross-border activity, the solution had to be global. (For pioneering analyses, see work by the Federal Reserve and the Office of Financial Research. For up-to-date information on the LEI, see here.)....
The manipulation of the London Interbank Offered Rate (LIBOR) began more than a decade ago. Employees of leading global firms submitted false reports to the British Banking Association (BBA), first to influence the value of LIBOR-linked derivatives, and later (during the financial crisis) to conceal the deterioration of their employers’ creditworthiness. U.S. and European regulators reported many of the details in 2012 when they fined Barclays, the first of a dozen financial firms that collectively paid fines exceeding $9 billion (see here). In addition to settling claims of aggrieved clients, these firms face enduring reputational damage: in some cases, management was forced out; in others, individuals received jail terms for their wrongdoing.
You might think that in light of this costly scandal, and the resulting challenges in maintaining LIBOR, market participants and regulators would have quickly replaced LIBOR with a sustainable short-term interest rate benchmark that had little risk of manipulation. You’d be wrong: the current administrator (ICE Benchmark Administration), which replaced the BBA in 2014, estimates that this guide (now called ICE LIBOR) continues to serve as the reference interest rate for “an estimated $350 trillion of outstanding contracts in maturities ranging from overnight to more than 30 years [our emphasis].” In short, LIBOR is still the world’s leading benchmark for short-term interest rates.
Against this background, U.K. Financial Conduct Authority CEO Andrew Bailey, recently called for a transition away from LIBOR before 2022 (see here). In this post, we briefly explain LIBOR’s role, why it remains an undesirable and unsustainable interest rate benchmark, and why it will be so difficult to replace (even gradually over several years) without risking disruption.

Courses in international economics usually introduce students to the impossible trinity, also known as the trilemma of open-economy macroeconomics: namely, that a fixed exchange rate, free cross-border capital flows, and discretionary monetary policy are incompatible. Why? Because, in the presence of free capital flows under a fixed exchange rate, private currency preferences (rather than policymakers) determine the size of the central bank balance sheet and hence the domestic interest rate. We’ve highlighted this problem several times in analyzing China’s evolving exchange rate regime (see here and here).
While many students learn that a country can only have two of the three elements of the open-economy trilemma, few learn that there also exists a financial trilemma. That is, financial stability, cross-border financial integration, and national financial policies are incompatible as well. The logic behind this second trilemma is that increases in financial integration reduce the incentives for national policymakers to act in ways that preserve financial stability globally. Put differently, as the benefits from financial stability policies spread beyond borders, the willingness to bear the costs of stabilizing the system at the national level decline. This has the important implication that, if we are to sustain increasing financial integration, then we will need greater international coordination among national financial regulators (see here, or for a much broader case for international economic governance, see Rodrik)....

Dear Vice Chair McHenry,
We find your January 31 letter to Federal Reserve Board Chair Janet Yellen both misleading and misguided.
It is in the best interest of U.S. citizens and our financial system that the Federal Reserve (and all the other U.S. regulators) continue to participate actively in international financial-standard-setting bodies. The Congress has many opportunities to hold the Fed accountable for its regulatory actions, which are very transparent. We hope that the new U.S. Administration will support the Fed’s efforts to promote a safe and efficient global financial system.
Your letter is filled with false assumptions and assertions.... Read More
