Money, Banking, and Financial Markets

Understand the principles, understand the future

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 Mr. Quarles,

Congratulations on your nomination as the first Vice Chairman for Supervision on the Board of Governors of the Federal Reserve System. We are pleased that President Trump has chosen someone so qualified, and we are equally pleased that you are willing to serve.

Assuming everything goes according to plan, you will be assuming your position just as we mark the 10th anniversary of the start of the global financial crisis. As a direct consequence of numerous reforms, the U.S. financial system—both institutions and markets—is meaningfully stronger than it was in 2007. Among many other things, today banks finance a larger portion of their lending with equity, devote more of their portfolios to high-quality, liquid assets, and clear a large fraction of derivatives through central counterparties.

That said, in our view, the system is not yet strong enough. In your new role, it will be your job to continue to fortify the financial system to make it sufficiently resilient.

With that task in mind, we humbly propose some key agenda items for the first few years of your term in office. We divide our suggestions into five broad categories (admittedly with significant overlap): capital and communications, stress testing, too big to fail, resolution, and regulation by economic function....
