Canadian dollar touches parity on continued broad-based USD weakness amid expectations for further quantitative easing by Fed, says Nobuaki Kubo, senior dealer at Brown Brothers Harriman Investment Services. Adding to those expectations, USD also weighed by Monetary Authority of Singapore's surprise decision to tighten its monetary policy, which contrasts sharply with mounting expectations for U.S. Federal Reserve to soon conduct more monetary easing. Adds, broad gains in Asian share markets also prompting investors to increase bets in commodity-linked currencies such as CAD, as gold hits new record high. USD/CAD Canadian dollar last 1.0005.
