Janet Yellen: The Fed is a Monetary Superpower

Federal Reserve Bank of San Francisco President Janet Yellen makes the case for the Fed as a monetary superpower, at least in Asia:

For all practical purposes, Hong Kong delegated the determination of its monetary policy to the Federal Reserve through its unilateral decision in 1983 to peg the Hong Kong dollar to the U.S. dollar in an arrangement known as a currency board. As the economist Robert Mundell showed, this delegation arises because it is impossible for any country to simultaneously have a fixed exchange rate, completely open capital markets, and an independent monetary policy. One of these must go. In Hong Kong, the choice was to forgo an independent monetary policy.

As in Hong Kong, Chinese officials are concerned about unwanted stimulus from excessively expansionary policies of the Fed and in other developed economies. Like Hong Kong, China pegs its currency to the U.S. dollar, but the peg is far less rigid.

Overall, we encountered concerns about U.S. monetary policy, and considerable interest in understanding the Federal Reserve’s exit strategy for removing monetary stimulus. Because both the Chinese and Hong Kong economies are further along in their recovery phases than the U.S. economy, current U.S. monetary policy is likely to be excessively stimulatory for them. However, as both Hong Kong and the mainland are currently pegging to the dollar, they are both to some extent stuck with the policy the Federal Reserve has chosen to promote recovery.

I am glad to see such a high-ranking Fed official agrees with me that the Fed is a monetary superpower. Now that we have this common understanding let us explore its implications for the saving glut theory. Let us do so by referencing an older post of mine:

[T]he Fed is a global monetary hegemon. It holds the world’s main reserve currency and many emerging markets are formally or informally pegged to dollar. Thus, its monetary policy is exported across the globe. This means that the other two monetary powers, the ECB and Japan, are mindful of U.S. monetary policy lest their currencies becomes too expensive relative to the dollar and all the other currencies pegged to the dollar. As as result, the Fed’s monetary policy gets exported to some degree to Japan and the Euro area as well. From this perspective it is easy to understand how the Fed could have created a global liquidity glut in the early-to-mid 2000s since its policy rate was negative in real terms and below the growth rate of productivity (i.e. the fed funds rate was below the natural rate).

Given the Fed’s role as a monetary hegemon the inevitability theme [i.e. the Fed had no choice but to accommodate the excess savings coming from Asia] underlying the saving glut view begins to look absurd. Moreover, the Fed’s superpower status raises an interesting question: what would have happened to global liquidity had the Fed run a tighter monetary policy in the early-to-mid 2000s? There would have been less need for the dollar bloc countries to buy up dollars and, in turn, fewer dollar-denominated assets. As a result, less savings would have flowed from the dollar block countries to the United States. In short, some of the saving glut would have disappeared.

I wonder what Yellen would say to the above paragraphs. More pointedly, I would love to ask her the following question: If the Fed can influence global liquidity conditions now why not in the early-to-mid 2000s? (I would also enjoy hearing Ben Benanke’s answer to this question.) If so, then surely the Fed had some role in the global housing boom. Chris Crowe of the IMF and I are working on a paper that documents this superpower status of the Fed and will be sure to send Janet a copy when it is done.

  1. Is it true that the FED has taken all the US gold reserves and that the US Government’s vaults at Fort Knox are near empty?
    Does anybody know?
