As 2007 draws to a close, the US dollar is making a nice comeback. Since December 1st, when “The Panic about the Dollar” was the headline on the front page of the Economist, the mighty buck has increased 600 pips against the British pound, 400 pips against the Euro and 300 pips against the Japanese Yen. What has changed? Has the curse of the magazine cover marked the bottom in the US dollar yet again? Some may argue that it has but the real driver is a shift in risk appetite. Stocks have given back their month to date gains and the big events over the past few weeks have all centered around the additional measures that central banks have taken to boost confidence in the financial markets. The end of the year has brought with it more announcements of subprime related losses which have done nothing but give investors better reasons to book profits and to delay any additional risk taking until the New Year. Today was no different. Even though S&P downgraded a bunch of US bond insurers and Morgan Stanley warned of challenging times ahead, the dollar was bought anyway as risk aversion continues to seep through the market. The results of the Term Auction Facility also came in. A 3 to 1 bid-to-cover ratio was neither good nor bad for the markets. So far, we are seeing a drop in LIBOR rates, which is the desired reaction of central banks. The only question is – [I]Will it last? [/I]If it doesn’t, the monetary helicopters will need to dump more liquidity into the markets. There was no US economic data released today but GDP, leading indicators and Philly Fed is due for release tomorrow. The GDP numbers are final figures; no revisions are expected which means that they should not be market moving. If there is a revision however, it will probably be to the downside. The Empire State manufacturing survey was particularly horrid which suggests that the Philly Fed could be as well. Whether this matters to the US dollar on the other hand is a different story.
