John Taylor on the dangers of a loose U.S. monetary policy and the effects this had in fueling a housing bubble in Spain, Ireland and other EU countries. Taylor points to the bubble ocurring in emerging market economies from low interest rates. Taylor says the ECB's interest rate moves in 2003-2005 were affected by the Fed's low interest rates. He estimates the ECB set rates about two percentage points too low leading to housing bubbles in EU countries. A similiar process is taking place today with the Fed's near zero interest rate policy. Taylor points to interest rates in a group of 18 emerging market economies- including Brazil, China, India, Mexico and Turkey, which have held interest rates on average about 5 percentage points below widely used benchmarks fueling a doubling of global commodity prices between 2009-2011. The U.S. Fed's policies make it harder for central banks in emerging market economies to take aggresssive action against bubbles developing in these countries. Taylor says his does not mean that the Fed should not pay attention to the U.S. unemployment rate and long term unemployed, but should keep in mind the negative effects of slowing demand in emerging market economies and in the EU as a result of its monetary policy of keeping rates at near zero for long periods of time. This feeds back to the U.S. economy at a critical time....
