For two weeks, the dollar has been hammered as foreign buyers shun the US currency.
As a result, the Canadian "loonie" is at its highest point in 30 years. The British pound is at its uppermost level since last September. Even the closely managed yen is at a six-month peak.
If the dollar were to continue falling, it could have wide ramifications:
* It could imperil the economy next year because Fed Chairman Ben Bernanke might have to defend the currency with higher interest rates.
* A lower-valued dollar makes imports more expensive, possibly ratcheting up the inflation rate. But it could also stimulate US exports, thus providing more jobs.
* This summer, Americans traveling abroad will feel as if everything is expensive. However, foreigners coming to America will feel as if the country is one giant Wal-Mart.
Behind the falling currency is a changing global economy. As the US Federal Reserve appears to be near the end of its round of interest-rate hikes, foreign banks are starting to hike their rates - which puts foreign currencies in higher demand, thus making the dollar less attractive. Thursday, in fact, the president of the European Central Bank indicated that rates could rise in Europe next month. At the same time, the giant US trade imbalance has produced a huge outflow of dollars to other countries, as well as the need to finance the ever-bigger US deficit. The deficit has attracted increasing scrutiny, most recently at a meeting of finance ministers in Washington last month.
In addition, the central banks of some foreign countries, which are key in financing the US deficit by buying US Treasury bills, are now less willing to do so. Instead, they're diversifying their reserve holdings with euros and yen.
"We seem to have reached a crossroads," says Anthony Chan, chief economist at JPMorgan Private Client Services in Columbus, Ohio. With foreign interest rates on the rise, he says, it will become harder to finance the US current account deficit.
Last year, the trade deficit in goods and services hit a record $726 billion, as US imports far exceeded exports. The gap has now reached 7 percent of the nation's gross domestic product, says Robert Scott, senior international economist at the Economic Policy Institute in Washington.
A big part of the rise - some 63 percent - is because of the surging price of oil. US energy officials expect the price to remain at these levels, if not higher, for some time.
The largest non-oil deficit is with China, which last year recorded a $202 billion surplus with the United States. On April 21, the world's finance ministers issued a statement calling for "exchange rate flexibility" in emerging economies with large current account surpluses, "especially China."
