Case Number Four: The Euro Reacts to New Information

According to an article in the Wall Street Journal (October 8, 1999):

The European Central Bank left interest rates unchanged but made clear it is seriously considering tightening monetary policy. The euro fell slightly on the ECBs announcement around midday that it would hold its key refinancing rate steady at 2.5%. But it rebounded as ECB President Wim Duisenberg reinforced expectations that a rate rise is in the works.

In the same story, the Wall Street Journal reported that the Bank of England didnt elaborate on its decision to leave its key repo rate unchanged at 5.25%. At the same time, sterling remains strong, which reduces the threat of imported inflation as well as continuing to pressure U.K. manufacturers. That could work against higher interest rates, which could send sterling even higher.

Required Question
