The US dollar traded significantly lower against major trading counterparts, as a surprise Federal Reserve interest rate cut eased risk aversion across financial market. The greenback, which has gained significantly on the recent flight to quality, halved its earlier week gains and sunk below previous two-month highs on a simultaneous Dow rally.

The Euro bounced off of fairly significant technical support, trading as many as 180 points off of lows to $1.3500 at time of writing. Forex traders likewise eased recent British Pound tumbles, with Cable erasing overnight losses to stay at $1.9822.

The US Federal Reserve surprised markets by dropping its discount lending rate by 50 basis points to 5.75 percent—a move said to forecast a more significant Fed Funds Rate cut through its September meeting. In its surprise vote to effectively ease monetary policy, the Fed said, “Financial market conditions have deteriorated, and tighter credit conditions and increased uncertainty have the potential to restrain economic growth going forward. In these circumstances, although recent data suggest that the economy has continued to expand at a moderate pace, the Federal Open Market Committee judges that the downside risks to growth have increased appreciably.” Combined with its recent injections of liquidity into Fed Funds markets, the central bank made it very clear that it is concerned over recent developments in domestic credit markets.

Fed Chairman Ben Bernanke seems intent to soften the effects of lending market troubles on the broader US economy. The chief central banker is well known for his willingness to swiftly respond to adverse risk, earning him the nickname of “Helicopter Ben” for statements on showering economies with money through economic crises. Whether or not “Helicopter Ben” is able to stem market tumbles and keep credit troubles contained remains the key question moving forward.

Given a pickup in perceived risk aversion, we could easily see the dollar strengthen against all majors other than the Japanese Yen.
