The U.S Dollar's weakness resumed, as global investors again embraced risks, reducing safe-haven demand for the U.S. currency, as traders took positions on the first day of the Federal Reserve monetary policy meeting. The U.S. Dollar also weakened on speculation that the Group of 20 leaders, meeting in Pittsburgh starting tomorrow, will call for a reduction in global trade imbalances that may cause further gains in the greenback's counterparts. The greenback traded at $1.4794 per EUR from $1.4790 yesterday, after declining to $1.4842 earlier on, the lowest level since September 22, 2008.

The hard-pressed Dollar had gained some ground Monday as equity markets weakened, with traders tying a decline in risk appetite to caution ahead of the Fed meeting, as well as the summit of Group of 20 leaders at the end of the week. But Tuesday's resumption of risk appetite may reflect views in the market that neither event is likely to produce meaningful changes analysts said.

Market sentiment toward the USD remains bearish. Analysts expect the Fed to signal its ultra-loose monetary policy will remain in place well into next year. Additionally, as the G20 to discusses rebalancing the global economy this will almost certainly further weaken the Dollar. The Federal Reserve is widely expected to leave Interest Rates unchanged. But markets will seek out clues on the Fed's asset purchases. Any sign that the Fed intends to continue its quantitative easing measures beyond this year could send the U.S Dollar to record lows.
