A weak dollar is the natural corollary of the long string of current account deficits run by the US in the past. As early as in 2000, leading economists like Obstfeld and Rogoff had already warned about the need for real dollar depreciation in the range of 35% to 50%, on a multilateral basis. From its peak in the year 2002 and October 2007, dollar has fallen on a multilateral basis - approximately 28% in nominal terms or about 25% in real terms.
Now, the big question is that how much real dollar depreciation should be expected, and, most importantly, to what extent the dollar fall will be accompanied by a global realignment of Asian currencies, supposedly lifting the pressure on the Euro. The strong interest in exchange rate predictions should not overshadow the need to understand the specific mechanisms by which real dollar depreciation is an essential step towards global adjustment. These mechanisms will, after all, shape the macroeconomic outlook in the next few years.
According to the Federal Reserve Bank of Atlanta, the average monthly value for the trade-weighted dollar index of 15 major currencies decreased 1.6% in November compared to the previous month. The dollar fell against all major sub-indexes. The greatest loss was against the European sub-index that saw a drop of 2.7% in November. The Pacific sub-index fell by 2%, whereas both the American and Pacific-excluding-Japan sub-indexes declined by 0.5%.
The classic sub-index, which is the analogue of the original Atlanta index, fell by 1.9%. The overall monthly index was 8.6% below its year-ago level. On a daily basis, the overall index was up 0.8% from the end of October to the end of November but remained 6.9% below its value at the end of November 2006.
