Financial panics are indeed dramatic and, for many private individuals and economic policymakers, traumatic. They are rarely of lasting significance to the fate of nations or their currencies, however, as the prompt recovery of Brazil, Korea, Mexico and Russia from their travails a decade ago demonstrates – unless some fundamental political upheaval takes place as well (as happened in the case of Indonesia).1 1In fact, the most recent empirical literature suggests that the fastest growing countries are not just those most subject to financial crises, but that those economies still come out ahead of their more stable counterparts, net of the cost of crises. See Tornell and Westermann (2005). Even the United States unilaterally shutting the gold window in 1971 did not lead to a sustained shift out of dollars or free fall in the currency. Though difficult to maintain, this long-term perspective is useful while the United States at present experiences a panic in its many interlocking asset-backed securities markets, following years of large current account deficits and a concurrent sell-off of the dollar against the euro. But it would be a mistake to read too much into recent developments. In fact, they obscure the reality that the euro is at a temporary peak of influence, and the dollar will continue to benefit from the geopolitical sources of its global role which the euro cannot yet or soon, if ever, match. If the dollar is displaced from its global role either now or in the coming couple of decades, it will likely and unfortunately be in favour of global monetary fragmentation induced by failures of US political leadership, rather than by ascension of the euro to a leading role based on purely economic developments. This significant dependence of the dollar's future role on political as well as economic factors, however, suggests that the dollar's global role is vulnerable to foreign policy failures – that in fact some of the decline in the dollar's global role of late is already due to the foreign policy failures of the Bush administration, not just to current account imbalances and financial turmoil. Therefore, were the dollar to be displaced from a dominant role there is a real risk of fragmentation of the global monetary system reinforcing political fragmentation. Were there just to be bipolarity with the euro, that would be a much happier prospect and at least a smoother transition with fewer implications. Alas, that is not to be. With news reports at the moment that everyone from fashion models and rap stars to New York City souvenir store owners are seeking payment in euros instead of dollars, and with McDonald's running a television advertisement for its Dollar Menu on US broadcasters beginning with a bunch of typical American office workers muttering ‘Dollar's looking weak …’, it seems only logical to think recent turmoil may be the big event that pushes the dollar off its pedestal as the dominant international currency. Given the apparent readiness of the euro to provide an alternative for all these concerned individuals to accept in lieu of dollars, or even into which to switch their investments, the euro's ascent to at least comparable status with the dollar has a surface and popular plausibility. Indeed, some observers predicted before the euro's launch that the euro would some day rival the dollar as a reserve currency, if not also as a private store of value and means of account, producing a bipolar monetary system.2 2See Alogoskoufis and Portes (1992), Bergsten (1997a, b) and Portes and Rey (1998). Note that most of these economic analyses focus specifically on the reserve currency role, given availability (for the most part) of data on official currency holdings and the assumption that many other aspects of the dollar or euro's usage would follow shifts in this usage. That is not to say that they dismiss other aspects such as pegging by third countries or private-sector invoicing, but do not focus on them. In this view, the fundamental drivers of reserve currency shares were the relative economic size, financial depth and commitment to low inflation of the dollar and euro economic blocs, all of which could be expected to converge over time, if not favour the euro.3 3Given the extraordinary historic convergence of monetary policies and resulting inflation rates globally, not just between the United States and the eurozone, I will largely this as a of shift between euro and and a of the shift in relative shares of the dollar and euro in which for the now to the of the has for the of the economic
