Government ownership of banks is still common around the world, despite the large number of privatizations that took place over the past four decades as governments reduced their role in the economy. On average, state-owned banks hold 21 percent of the assets of the banking system worldwide. In Latin American and Caribbean countries, the public banks’ share is about 15 percent, with some of them showing very large shares, for instance, Argentina, Brazil, Uruguay, and Costa Rica are all over 40 percent (see Figure 1).

State-owned banks play an important role in the financial system. They fulfill functions that are not performed by private banks, provide financing for projects that benefit the rest of the economy, and provide countercyclical lending (lending more when the economy is weak). But public banks usually respond to the needs of governments owing to the state’s obvious involvement in their administration. As a result, government’s participation in the banking system may weaken fiscal discipline by allowing the public sector to access financing that they would not obtain from other sources.

Large banks were at the center of the recent financial crisis. The public dismay at costly but necessary bailouts of “too-big-to-fail” banks has triggered an active debate on the optimal size and range of activities of banks.

But this debate remains inconclusive, in part because the economics of an “optimal” bank size is far from clear. Our recent study tries to fill this gap by summarizing what we know about large banks using data for a large cross-section of banking firms in 52 countries.

We find that while large banks are riskier, and create most of the systemic risk in the financial system, it is difficult to determine an “optimal” bank size. In this setting, we find that the best policy option may not be outright restrictions on bank size, but capital—requiring  large banks to hold more capital—and better bank resolution and governance.
