For readers of the Daily Currency Focus, it should be no surprise that the dollar has continued to weaken. On Wednesday, we said that the actions by the Federal Reserve have cemented the downtrend in the U.S. dollar. Given how currency traders have responded to previous Quantitative Easing threats and announcements, the EUR/USD could realistically hit 1.40 (see charts). Although equities have given back its gains and bond yields have rallied, the moves in the currency and commodity markets indicate that the Fed’s actions will have a lasting impact on the financial markets. As we look forward to more dollar weakness, it is worthwhile to consider how a weaker dollar impacts the global economy.

For the second day in a row, the U.S. dollar has appreciated significantly against the Euro and is also trading higher against the New Zealand dollar and Swiss Franc. However, the extent of today’s rally in the greenback basically ends there. The dollar is practically unchanged against the British pound and Australian dollars and is trading lower against the Canadian dollar and Japanese Yen. The 2.3 percent sell-off in U.S. equities coupled with the outperformance of the two lowest yielding G7 currencies indicates that risk aversion is the dominant theme. Yet, with no major U.S. economic data or market moving news over the past 48 hours, traders may be wondering, what changed. As recently as last week, investors were optimistic about a turnaround in the global economy following the more substantial outcome from the G20 meeting.

The rally in U.S. equities and the improvement in risk appetite drove the U.S. dollar lower against all higher yielding currencies. Thanks to some extra efforts by the G20 and relaxation of mark to market accounting by the Financial Accounting Standards Board (FASB), investors have become more optimistic. However a big event risk lies ahead for the U.S. dollar and it remains to be seen whether the positive sentiment following the G20 and FASB can be sustained. The non-farm payrolls report is traditionally one of the most market moving pieces of data for the foreign exchange market and with the strong possibility of another sharp decline in jobs, it is too early to completely buy into the recovery story (How Could the Dollar React to Non-Farm Payrolls?).

FOMC's stunning announcement yesterday that it will buy up to $300 Billion in Treasury bonds took the currency market by surprise and rallied the EUR/USD by more than 500 points in less than 24 hours. As we wrote earlier the FOMC announcement ,” represents an 'all-in' bet on massive monetary stimulus in order to stem the worst contraction in the US economy since World War II. The move is of course wildly dilutive to the currency with nearly $1 Trillion created out of thin air. Little wonder then why the dollar collapsed across the board even as other asset classes rallied. It also indicates that the Fed may have come to the conclusion that the two biggest customers for US debt – China and Japan – may be unable or unwilling to provide additional capital to finance the gargantuan expansion of US fiscal spending this year and next.”

A bank report that we read this week had an interesting line summarizing investors’ attitude towards the U.S. dollar over the past few months. They said that being long dollars means being long pessimism and we believe that this is a valid description of the recent price action in the currency markets. Today, the dollar weakened against every major currency except for the Japanese Yen. This weakness as baffling as it may seem is more of reflection of the market’s optimism than pessimism because equities are higher and gold prices are lower.

Volatility has ripped through the foreign exchange market as the U.S. dollar gave back its earlier gains. Safe haven flows drove the dollar higher at the beginning of the U.S. trading session, but the currency lost value when equities took off. The big story in the foreign exchange today was the Swiss National Bank’s controversial and nuclear decision to intervene in the currency market, raising fears of a global FX war. By coming into the foreign exchange market to sell Swiss Francs, the central bank has driven the Euro and U.S. dollar sharply higher. The gains in these currencies were exacerbated by the rally in U.S. equities and a stronger retail sales report. The rally in the foreign exchange market today indicates that risk appetite has improved.

As we have promised, trading currencies have become more interesting following the interest rate decisions in Europe. The next 24 hours should prove to be just as exciting for forex traders with the February non-farm payrolls report due for release. The US dollar has rallied significantly ahead of the payrolls report, which is traditionally the single most market moving economic data for the EUR/USD. The cohesive rally in the US dollar and the price of gold along with the sell-off in US equities indicate that risk aversion is the main theme of the day. This also provides a clue on how the dollar could trade following Friday’s non-farm payrolls report (February Non-Farm Payrolls Preview).

The two biggest event risks for currency traders over the next 24 hours are the Bank of England and European Central Bank interest rate decisions.

Capital flight has driven the US dollar higher. On a day when President Obama signed the Economic Stimulus Package into law, the banking turmoil in Europe and the resignation of Japan’s Finance Minister has turned investors away from other major currencies. Even though the greenback is yielding next to nothing, investors are willing to park their money with the US government as long as they keep it safe. The lack of negative game changing news from the US has been very positive for the US dollar. The greenback and gold prices have been moving in tandem since January 14th. This unusual correlation is actually sending a strong message to currency traders.
