The USD continues to dominate conversation in forex circles, as investors ponder whether the currency will fall further or whether it has already sunk as low as it can go. One commentator recently encapsulated the debate into six factors, three bullish on the Dollar and three bearish.  Number one on the side of bearishness is the interest rate situation. Short term US rates are negative in real terms, and savvy investors are using the Dollar to fund carry trades in order to take advantage of higher yields outside the US. The second and third factors are technical: based on one measure, the Dollar is not nearly as "oversold" as it was in 1992, the last time the Dollar suddenly reversed a multi-year decline.  In addition, the "open interest" on the Euro is not as large as it should be if traders were preparing to dump it.

First on the list of factors supporting a bullish outlook is the US recession. This is somewhat counter-intuitive, but history shows that US economic weakness typically coincides with Dollar strength.  Perhaps this is because many countries depend on the US to drive the global economy.  In fact, the Dollar is already rising against certain emerging market currencies that rely on the US as an export market. In addition, overseas investors tend to park their capital in the US during periods of global economic instability because of its continued reputation as a safe haven.  Second, the economies of the UK and the EU are already weak and growing weaker every day.  The only reason their respective Central Banks have not eased monetary policy is because they are also focused on combating inflation. However, they may soon have to sacrifice price stability in favor of economic growth, at which point interest rate differentials will begin to reverse themselves in favor of the US.  The final reason for bullishness is technical; based on a series of indicators different from those listed above, the Dollar IS oversold  and the recent slip downward may presage an upward shift.

In a research note, two economists from Morgan Stanley predicted that the Euro will soon come crashing down, failing in its bid to rival the Dollar as a viable reserve currency. They observed that in the beginning of the decade, the Euro was viewed as joke from an economic standpoint. Since long-term economic fundamentals can't reverse themselves in only a few years, they reasoned that the Euro's rise must instead be a product of financial (capital flows) trends. Furthermore, as the EU becomes further integrated, a need will develop to diversify capital outside of the EU, thus reversing the trend of the last few years of diversification within the EU. The Globe and Mail reports:

The euro is overvalued because institutional investors...world have been diversifying out of their home markets at the same time as European investors have largely been diversifying within their home market.

For a recent article, EuroMoney Magazine pulled together some of the top currency analysts on Wall Street for a comprehensive discussion on the state of forex.  The conversation zigs and zags, covering such varied topics as volatility, interest rates, trading strategies, emerging markets, central banks and market infrastructure.  Among other things, it was noted that volatility has surged by 50% since the inception of the credit crunch, returning to levels last seen at the beginning of the decade.  One of the participants broached the possibility of deflation, but that was quickly dismissed by the others due to surging food and energy prices. It was also noted how Central Banks are caught between fighting inflation and facilitating growth, in deciding whether to raise or lower rates, respectively. The main theme in the markets is the sagging Dollar, which is being punished for both economic and strategic reasons as investors sell it in response to the economic downturn and to fund carry trades. Finally, one participant commented that despite growth in liquidity, forex strategy hasn't evolved much, and the markets remain vulnerable to a huge sell-off due to the "mob mentality."

The lack of fanfare not withstanding, the Chinese Yuan, or RMB, continues to appreciate against the USD. This week, it crossed the psychologically important barrier of 7 RMB/Dollar, a level last seen in the 1990's. Since its revaluation nearly three years ago, the Yuan has risen 16% against the Dollar, a rate which appears to be growing exponentially given the 4.5% rise already notched in 2008. Due to the Dollar's continued weakness against all of the major currencies, the RMB has actually fallen against the Euro over the same period. Most analysts reckon the Yuan will continue appreciating, perhaps to 6.5 by year-end. The New York Times reports:

"The appreciating renminbi is a signal the Chinese government is sending to the export companies to switch away from the U.S. and other overseas markets and turn toward the domestic market."

Simply having a hand at the central bank’s tiller will do much to restore global confidence in Japan and its ability to manage its $5 trillion economy, economists and former bank officials said.

The Dollar Index traded on ICE Futures in New York, which tracks the currency against those of six trading partners, dropped 0.2 percent to 72.049, its third straight decline. It was at a record low of 70.698 on March 17.

In recent months, the credit crunch has ignited a global trend towards risk aversion.  As a result, a correlation has developed between equities, which serve as a proxy for risk, and certain currencies.  The Forex Blog previously covered the link between the S&P 500 and the Japanese Yen, whereby the Japanese Yen moved inversely with the S&P as a decline in  risk appetite led carry traders to unwind their positions. Perhaps, this connection can be seen in other currencies.  Since the forex markets are open 24 hours a day and are the most liquid financial markets in the world, macroeconomic events are often priced into currencies before they are priced into equities. In addition, carry trading strategies have expanded beyond the Japanese Yen.  In fact, the USD is now a decent candidate as interest rates are negative,when adjusted for inflation.  Thus, an increase in risk appetite could simultaneously boost the S&P and punish the Dollar!
