The falling US dollar has emerged as a source of profound global macro-economic distress. The question now is how bad that distress will become. Is the world economy at risk? There are two possibilities. If global savers and investors expect the US dollar's depreciation to continue, they will flee the currency unless they are compensated appropriately for keeping their money in the US and its assets, implying that the gap between US and foreign interest rates will widen. As a result, the cost of capital in the US will soar, discouraging investment and reducing consumption spending as high interest rates depress the value of households' principal assets: their houses.
The resulting recession might fuel further pessimism and cutbacks in spending, deepening the downturn. A US in recession would no longer serve as the importer of last resort, which might send the rest of the world into recession as well. A world in which everybody expects a falling US dollar is a world in economic crisis.
By contrast, a world in which the US dollar has already fallen is one that may see economic turmoil, but not an economic crisis. If the US dollar has already fallen -- if nobody expects it to fall much more -- then there is no reason to compensate global savers and investors for holding US assets.
On the contrary, in this scenario there are opportunities: the US dollar, after all, might rise; US interest rates will be at normal levels; asset values will not be unduly depressed; and investment spending will not be affected by financial turmoil.
Of course, there may well be turbulence: When US wage levels appear low because of a weak US dollar, it is hard to export to the US, and other countries must rely on other sources of demand to maintain full employment. The government may have to shore up the financial system if the changes in asset prices that undermined the US dollar sink risk-loving or imprudent lenders.
But these are, or ought to be, problems that we can solve. By contrast, sky-high US interest rates produced by a general expectation of a massive ongoing US dollar decline is a macroeconomic problem without a solution.
Yet so far there are no signs that global savers and investors expect a US dollar decline. The large gap between US and foreign long-term interest rates that should emerge from and signal expectations of a falling US dollar does not exist. And the US$65 billion needed every month to fund the US current-account deficit continues to flow in. Thus, the world economy may dodge yet another potential catastrophe.
That may still prove to be wishful thinking. After all, the US' still-large current-account deficit guarantees that the US dollar will continue to fall. Even so, the macroeconomic logic that large current-account deficits signal that currencies are overvalued continues to escape the world's international financial investors and speculators.
On one level, this is very frustrating: We economists believe that people are smart enough to understand their situation and capable enough to pursue their own interests. Yet the typical investor in US dollar-denominated assets -- whether a rich private individual, a pension fund, or a central bank -- has not taken the steps to protect themselves against the very likely US dollar decline in our future.
In this case, what is bad for economists is good for the world economy: We may be facing a mere episode of financial distress in the US rather than sky-high long-term interest rates and a depression. The fact that economists can't explain it is no reason not to be thankful.

In a summer of intense political maneuvering, Taiwanese, whose democratic vibrancy is a constant rebuke to Beijing’s authoritarianism, delivered a powerful verdict not on China, but on their own political leaders. Two high-profile recall campaigns, driven by the ruling party against its opposition, collapsed in failure. It was a clear signal that after months of bitter confrontation, the Taiwanese public is demanding a shift from perpetual campaign mode to the hard work of governing. For Washington and other world capitals, this is more than a distant political drama. The stability of Taiwan is vital, as it serves as a key player
Much like the first round on July 26, Saturday’s second wave of recall elections — this time targeting seven Chinese Nationalist Party (KMT) lawmakers — also failed. With all 31 KMT legislators who faced recall this summer secure in their posts, the mass recall campaign has come to an end. The outcome was unsurprising. Last month’s across-the-board defeats had already dealt a heavy blow to the morale of recall advocates and the ruling Democratic Progressive Party (DPP), while bolstering the confidence of the KMT and its ally the Taiwan People’s Party (TPP). It seemed a foregone conclusion that recalls would falter, as
The fallout from the mass recalls and the referendum on restarting the Ma-anshan Nuclear Power Plant continues to monopolize the news. The general consensus is that the Democratic Progressive Party (DPP) has been bloodied and found wanting, and is in need of reflection and a course correction if it is to avoid electoral defeat. The Chinese Nationalist Party (KMT) has not emerged unscathed, either, but has the opportunity of making a relatively clean break. That depends on who the party on Oct. 18 picks to replace outgoing KMT Chairman Eric Chu (朱立倫). What is certain is that, with the dust settling
Mainland Affairs Council Deputy Minister Shen You-chung (沈有忠) on Thursday last week urged democratic nations to boycott China’s military parade on Wednesday next week. The parade, a grand display of Beijing’s military hardware, is meant to commemorate the 80th anniversary of Japan’s surrender in World War II. While China has invited world leaders to attend, many have declined. A Kyodo News report on Sunday said that Japan has asked European and Asian leaders who have yet to respond to the invitation to refrain from attending. Tokyo is seeking to prevent Beijing from spreading its distorted interpretation of wartime history, the report
