The Dollar strengthened Tuesday as new doubts surfaced about Greece's financial situation and economic recovery. Supporting the USD further were minutes from the FOMC meeting which trimmed the forecasts for economic growth and inflation while not giving any hints as to when the extended period of low rates is expected to change in the near future.

Contributing to the greenback's strength was the fact that European and British markets were closed Monday and last Friday for Easter, and Tuesday was the first opportunity of markets to react to the positive economic data released from the U.S during those days, particularly Monday's ISM Non Manufacturing PMI and Pending Home Sales.

The Canadian Dollar reached parity versus the USD Tuesday, trading higher than the greenback for the first time since July 2008 as Crude Oil Prices continue to rise on prospects of an increase in interest rates ahead of the U.S.
