This article for the first time compares the Federal Reserve’spowersas lender of last resort (‘LLR’) and its ability to fight contagion, with its three major peers, the Bank of England (the ‘BOE’), the European Central Bank (the ‘ECB’) and the Bank of Japan (the ‘BOJ’). It concludes that the Federal Reserve (the ‘Fed’) is currently the weakest of the four, largely due to a hostile political environment for LLR powers, which are equated with bailouts, and restrictions placed by the 2010 Dodd–Frank Act on the Fed’s ability to loan to non-banks, whose role in the financial system is ever-increasing. This is a concern for the global as well as the US financial system, given the economic importance of the United States and the use of the dollar as a reserve currency.
