In recent years, the idea of parity seemed to pop up repeatedly in forex markets. First, the Canadian Dollar breached the mythical 1:1 barrier against the USD; then, it looked as though the Australian Dollar would follow suit. The most recent battle for parity is being waged across the Atlantic Ocean, between the British Pound and the Euro. Both economic and monetary circumstances favor the Euro, as the housing crisis pummeled the UK economy and the UK Central Bank subsequently embarked on a steep program of monetary easing. The Euro has probably also received a boost from the perception that the EU is one of the most stable economies and investing locales, outside of the US. In any event, investors tend to get carried away with psychological milestones and ignore economic fundamentals, which means the Euro could quickly achieve parity, before pulling back. The Wall Street Journal reports:

On Monday, one euro briefly bought almost 98 pence, a new record. That paves the way for parity “as early as this week,” wrote Ashraf Laidi, chief market strategist at CMC Markets.

While the Yen's 30% rise in 2008 is no mystery (a result of the unwinding of carry trades), its performance nonetheless defies economic fundamentals. Exports have fallen and industrial production has collapsed, such that recession now appears inevitable. Japan is not alone in this regard, as a number of economies have suffered unnecessarily as a result of excessive volatility in currency markets. The solution could be the so-called "Tobin tax," which aims to limit forex speculation by levying a nominal tax on short-term currency trades. The proceeds from such a tax would be used to restore some equilibrium in forex markets by providing Central Banks with funds for direct intervention. While the tax itself has never been implemented, countries have previously taken to cooperating on forex matters for the sake of global macroeconomic stability. Seeking Alpha reports:

The Central Bank of Vietnam finally acceded to reality and devalued its currency, the Vietnam Dong, by 3%. Prior to the change, the Dong (as well as its neighbor, the Chinese Yuan, which has also experienced a decline) was one of the few relative winners of the credit crisis. Perhaps this was because the currency had already depreciated significantly in recent years (35% since 1994), as well as because it remains fixed to the Dollar and hence it is impossible for the markets to short it when it becomes overvalued. Vietnam continues to be plagued by double-digit inflation and a surging current account imbalance, which suggest that the currency will probably have to suffer an additional 'correction' before reaching a sustainable level. In fact, the black market rate remains well below the official rate, reports Bloomberg News:

Citi Analyst Steven Wieting opined: "If you want yield, you'll have to take some risk." With borrowing rates suddenly close to zero and the Fed saying it will keep them at “exceptionally low levels ... for some time, you'll get as little of it from government-issued debt as possible."

Yesterday, the Forex Blog reported that the Yen could soon peak as a result of renewed interest in the carry trade. On the other side of this equation are emerging market currencies, most of which offer interest rates well above their industrialized counterparts. The spread between South Africa's benchmark interest rate and the rates of Switzerland, Japan, and the US, now exceeds 10%. As a result of near-zero rates in these countries, investors have once again taken to scouring the earth for yield. Apparently, government stimulus plans and monetary incentives have restored confidence in risk-taking. South Africa is especially poised to benefit, as it is one of the world's largest producers of gold, which recently resumed its upward trend. Bloomberg News reports:

On the basis of a 25% appreciation against the Dollar, 2008 marked the strongest year for the Japanese Yen since 1972, as the credit crisis caused a rapid unwinding of carry trades as investors abandoned risky positions. 2009 may not be as auspicious for the Yen, however, as a bevy of factors coalesces to halt its upward progress. First of all, global credit and forex markets have begun to stabilize over the last few months. The seemingly unending US government bailout has restored confidence in riskier sectors, such as the automotive sector. Coupled with a cut in Japanese interest rates, investors are being lured back into the carry trade. In addition, Japanese economic officials are becoming more vocal about the Yen's rise, which is threatening to send the export-dependent economy into another deep recession. It is therefore conceivable that the Central Bank could intervene on behalf of the Yen, despite the pleas of the G8. Bloomberg News reports:

Anyone curious about whether China is intentionally allowing the RMB to depreciate, need look no further than the Central Bank's latest forex reserve figures, which registered a decline for the first time in nearly six years. At the same time, Chinese trade figures indicate that exports fell for the first time in seven years, which limits the government's ability to build up new reserves. As a result of the credit crisis, it's conceivable that the Central Bank will continue to spend down its reserves in order to provide a boost to its faltering economy. US President-elect Obama will have to deal with such forces if he wishes to successfully take on China's currency policy. Otherwise, the RMB currency could appreciate in 2009, bucking its trend over the last few years.

As 2008 comes to a violent end, forex analysts are releasing their predictions for 2009. Most believe that risk aversion and interest rate discrepancies will cease to weigh on forex markets, especially compared to 2008, when investors unwound carry trades and parked their money in low-yielding (but apparently less risky) US and Japanese securities. Instead, investors will probably begin to focus more on economic fundamentals. With regard to the Dollar, this approach could work either way. On the one hand, it is conceivable that the US will outperform (this could translate into a milder recession) the EU and Japan, since the Fed's interest rate cuts were implemented at such an early stage. On the other hand, the US twin deficits continue to expand, which suggests the possibility of long-term inflation as well as a potential reluctance in foreigners to continue to lend to the US. Marketwatch reports:

To be sure, the dollar's 2009 trajectory depends a lot on what the U.S. and global economies do, and when they do it. The U.S. recovery could begin midyear, or the clouds could linger until the fourth quarter or even longer.

The perfect economic storm continues to brew in Russia; the financial crisis is sapping demand for Russian securities, and a decline in the price of oil (as well as other commodities) has turned the balance of trade from surplus to deficit. As a result, Russian banking officials seem resigned to a depreciation in the Ruble, but are understandably averse to a sudden devaluation, which could shock the economy into complete collapse. Nonetheless, in the last week, the currency recorded record drops as the Central Bank took advantage of Dollar weakness to adjust the band in which the Ruble is permitted to fluctuate (read: decline). Given continued weakness in the price of oil, combined with a faltering economy and surging domestic unemployment, investors should continue to expect precipitous drops in the Ruble, as it sinks to a sustainable level. Bloomberg News reports:

Troika Dialog, the nation’s oldest investment bank, and Goldman Sachs Group Inc. predict the ruble will have to weaken by at least 20 percent against the basket to reignite an economy stymied by a 62 percent drop in oil prices since July.

More than a week after America's Federal Reserve Bank slashed its benchmark interest rate to the historic (low) level of .25%, investors are still struggling to assess the implications. The immediate reaction was mostly positive, as Central Banks around the world (namely Hong Kong and Japan) quickly followed suit, and stocks rallied. In other words, investors were buoyed by the belief that Central Banks can and will employ all available financial tools to maintain acceptable liquidity in financial markets and to prevent the economic downturn from turning into a depression. On the other hand, forex traders were understandably dismayed by the growing gap between US and foreign interest rates, as well as the inflationary implications of the Fed's plan to essentially print money and inject it directly into the economy. The Associated Press reports:

"While there was applause for the (Fed) cuts...investors are now standing back and reflecting further on what that means," said...an analyst. "Some nervousness has been expressed in the currency markets. We have seen a weakened dollar, which has probably had an effect on the markets across the board."
