Quantitative Easing and the Renminbi

CAMBRIDGE – The United States Federal Reserve’s policy of “quantitative easing” is reducing the value of the dollar relative to other currencies that have floating exchange rates. But what does the new Fed policy mean for one of the most important exchange rates of all – that of the renminbi relative to the dollar and to other currencies?

The effect of quantitative easing on exchange rates between the dollar and the floating-rate currencies is a predictable result of the Fed’s plan to increase the supply of dollars. The rise in the volume of dollars is causing the value of each dollar to fall relative to these currencies, whose volume has remained constant or risen more slowly.

The Fed’s goal may be to stimulate domestic activity in the US and to reduce the risk of deflation. But, intended or not, the increased supply of dollars also affects the international value of the dollar. American investors who sell bonds to the Fed will want to diversify the dollars that they receive from it. One form of that diversification is to buy foreign bonds and stocks, driving up the value of those currencies.

The Fed’s policy of increasing the supply of dollars also increases investors’ concern about the future rate of inflation in the US. That provides a further reason for American investors to shift part of their portfolios from dollars to other currencies that are not likely to experience rising inflation.
