Yesterday, the Forex Blog published a commentary piece exploring the rally in the Dollar that is currently under way. While the rally is strongly grounded in fundamentals (falling commodity prices, the spread of the credit crisis to the rest of the world), some traders are nonetheless crying foul. They claim that the European Central Bank (with or without the assistance of the US) furtively intervened in forex markets to the tune of 10 Billion Euros. Even if their claim is true, it is unlikely to have meaningfully contributed to the Dollar rally, since the amount in question is quite small. Central Bank intervention would require an expenditure of at least $100 Billion to be even partially successful. Japan, for example, has spent nearly $1 Trillion (if its foreign exchange reserves are any indication) holding down the Yen over the last decade. Besides, the Dollar rally is unsurprising, given certain recent economic developments and the benefit of hindsight. Minyanville.com reports:

Whenever global liquidity tightens relatively speaking, it is very US$ supportive. Obviously, there are always time lags between economic events until the the market perceives them. So as a result of weak demand in the US, lower imports, the demand for oil declines, and that led to a tightening of global liquidity which led to the strong dollar

Over the last month, the Dollar has rallied tremendously, rising over 7% against its main adversary, the Euro. The price of gold, which serves as an inverse proxy for investor confidence in the USD, has fallen dramatically. As a result, many analysts have proclaimed that the Dollar has (permanently) bottomed out, and are busying themselves preparing projections for how high the Dollar will rise. But is the Dollar rally sustainable?

In the short-term, I would argue the answer is yes. The bubbles in the various sectors of commodity markets seem to have partially deflated, with oil and certain food staples well below the record highs they touched earlier in the year. As a result, inflation may soon begin to abate, and return to a comfortable level as early as 2009. More importantly, the US economy was among the first to be affected by the credit and real estate crises. Some analysts have argued that the worst developments have already come to pass. The crisis has since spread to the global economy, with other countries sharing in some of the burden. The result is that the US economic and monetary cycle is probably ahead of most of its peers. Accordingly, by the time the full impact of the crisis is felt by the rest of the world, the US should firmly be on the path to recovery. As other Central Banks move to ease their respective monetary policies, the Fed should be in a position to hike rates, providing further support for the Dollar.

As a result of this belief, US capital markets have received a sudden inflow of capital. This trend has been further buoyed by the notion that the US is the safest place to invest in times of crisis is gaining traction among investors. If the credit crisis continues to spread, this notion will no doubt be reinforced.

The long-term picture is of course more nuanced. The US will hardly emerge from the current crisis unscathed, and the ultimate cost of the credit crisis could exceed $1 Trillion. In addition, the US is unlikely to be shamed into changing its nasty habit of spending more than it saves. Accordingly, the twin deficits, those permanent thorns in the side of the Dollar, will probably persist. In addition, recent history suggests that investors are slow to absorb the lesson that There is No Such Thing as a Free Lunch. Despite the horrible collapse of the dot-com bubble, investors piled willy-nilly into the real estate market, with the result speaking for itself. Analysts are already speculating where the next bubble will occur; perhaps in alternative energy?

In conclusion, while the near-term prospects of the Dollar are surprisingly bright, the long-term prognosis is less so. There is no indication that the structural weaknesses in the US economy that led to the credit crisis and the multi-year decline in the USD that preceded it, will abate following its resolution. The future is inherently unpredictable, but I would expect the Dollar to continue declining once the global economy is back on track, perhaps in 2010.

In his headline remarks at the annual conference for members of America's Federal Reserve Bank, Chairman Ben Bernanke reiterated his comfort with the current level of interest rates. He argued that while interest rates are certainly low by historical standards, a decline in inflation over the next few months should bridge the gap between the two. In addition, the credit crisis remains ongoing, and it is clear that Bernanke is more concerned about economic growth than inflation. Bernanke's comments are supported by the recent Dollar rally and the simultaneous easing of commodity prices. At the same time, data indicate that over the last twelve months, prices have risen at the fastest pace in nearly 17 years. If futures contracts are any indication, investors basically accept Bernanke's position, but not by much. Bloomberg News reports:

Traders added to bets that the Fed will increase borrowing costs by the end of the year, futures prices show. Odds of at least a quarter point boost in the main rate by the end of December rose to 32 percent from 18 percent yesterday.

Almost all of the speculation surrounding the Chinese Yuan is aimed at predicting the point at which the currency will stop rising. Will it stop at 6.5? 6? 5? 1? But what if the currency has already peaked, at least temporarily? The Central Bank of China is now openly airing its concerns about a slowing economy, which it believes is more problematic than the country's surging inflation rate. Accordingly, it will probably relax interest rates and slow the appreciation of the currency, in order to give businesses and exporters the leverage they need to keep the economy going. In fact, the Central Bank already announced a $50 Billion plan to prop up ailing capital and property markets. Such measures are likely to further stoke the fires of inflation, at a time when prices are already rising at the fastest pace in a decade. The futures markets have been quick to take note, and expectations for Yuan appreciation are falling accordingly. Bloomberg News reports:

[Futures contracts] suggest the yuan will reach 6.6060 per dollar in the next 12 months, an advance of 3.8 percent from the current exchange rate. Two weeks ago the contracts, predicted an advance of 5.3 percent. At the start of last month, they priced in a 6 percent rise.

The USD is officially trending upwards, having appreciated over 7% against the Euro in only a few weeks. Of course, hindsight is 20/20, and some analysts now claim that support for the Dollar had been building for several months. They point out that the first break for the Greenback came in March when the Fed stopped lowering interest rates. Then, at a meeting of the G8 nations, several high-ranking officials indicated that they were unhappy with the recent decline of the Dollar and suggested that coordinated intervention should be effected in order to prevent a further collapse of confidence. While this "verbal intervention" was ultimately not backed by any kind of substantive action, investors apparently took the hint.

Further comments by America's Federal Reserve Bank and the Secretary of the Treasury made clear that the US remained committed to the Strong Dollar Policy. A reprieve in the rise of commodity prices, followed by the proposed bailout of the two cornerstones of American's sprawling mortgage industry, convinced currency traders that the world's economic policymakers simply would now allow the Dollar to fall further. Lo and behold, the Dollar failed to break through a resistance level at $1.60/Euro (near a record low), and has since rallied sharply. The International Business Times reports:

It seems that that the big money had committed to a long Dollar, and was waiting for the economic slowdown to spread to the Euro Zone. Once the Euro Zone began to experience a slowdown, it just became a matter of time before the short positions that had been built for several months would pay off.

While not yet in the same league as other popular emerging market currencies, the Brazilian Real and Mexican Peso are sure to join their ranks soon; both currencies have risen markedly over the last few years, and have performed especially well in the year-to-date. They have been propelled by interest rates that are generously high, especially compared to those of the US and EU. Brazil's benchmark rate currently stands at 13%, while Mexico's equivelent rate is slightly lower, at 8%. In fact, interest rates are quite high throughout the region, including in Peru and in Chile. Anlaysts expect most of these Central Banks will further tighten their leding rates because of surging inflation, which would provide further impetus to the upward marches of their respective currencies against the Dollar. Reuters reports:

"We see EMEA (European, Middle Eastern and African) central banks as reaching the end of their (monetary) tightening cycles, whereas there is still more to go from Latin America," wrote Barclays Capital.

In historical periods of financial crisis, where did investors turn? The answer: the US. Some analysts thought that this logic would be turned on its head during the current credit crisis, since the reputation of the US as investing safe haven would surely be undermined by its role in the global economic slowdown. Over the last couple weeks, however, investors have returned en masse to US capital markets, sending US equities as well as the US Dollar to new highs. This has created a self-fulfilling cycle whereby a more valuable Dollar is driving commodity prices lower, which in turn, will benefit the US economy and drive the Dollar even higher. Perhaps the new logic is not so different from the old: that although it was the US that is primarily responsible for the credit crunch, it is also the US which is most likely to lead the global economy out of it. The Los Angeles Times reports:

Whether we come out of this first remains to be seen. But some grim economic data from Europe and Japan in recent weeks at least confirm that the slowdown has gone global. In that sense, the U.S. is the devil you know.

The Canadian Dollar continues to lose its luster. Falling natural resource prices and the credit crunch have combined to exact a devastating blow on the Canadian economy, causing it to actually contract in the most recent month for which data is available. Now, the Central Bank is predicting that the economy will expand by only 1% in 2008. Most economists expect that Canadian Monetary Policy will soon lag US policy, especially if the Fed raises interest rates to combat inflation. Based on these developments, the consensus is that the Canadian Loonie is significantly overvalued, and will lose some of its value over the next few years, falling to a more sustainable level against the US Dollar. Bloomberg News reports:

The loonie will slide to C$1.05 by the end of December, and to C$1.09 by the start of 2010, according to the median estimate of 31 strategists surveyed by Bloomberg.
