The dollar's short-lived comeback
To that end, the latest reading on manufacturing activity fell more sharply than expected in April, while retail sales, which drive two thirds of economic activity in the United States, also suffered a decline last month.
At the same time, there has been further fallout in the housing market and unemployment is on the rise.
Even though the weakened dollar has helped boost the nation's exports by making goods manufactured in the United States more attractive to foreign buyers, the nation's current account deficit - which measures trade with the rest of the world - is still massive.
The deficit was a whopping $738.6 billion at the end of last year. While that's down from $811.5 billion in 2006, it's still large enough to be a concern since the current account deficit has to be covered by borrowing from overseas investors.
If these investors pull their money from the U.S., that could result in a cycle of falling stock and bond prices and ultimately a further decline in the value of the dollar.
In addition, foreign central bankers have been reluctant to cut interest rates, which has also helped spur the dollar's weakness. Both the European Central Bank and the Bank of England held interest rates steady last week.
Still, it is understandable why a growing number of experts are betting on a dollar rebound.
Foreign investors, for example, are buying more U.S. securities than they are selling, which help supports the dollar.
According to the most recent Treasury International Capital report, a monthly reading which measures foreign investment flows, net foreign purchases of long-term U.S. securities were $80.4 billion in March, up from net purchases of $64.9 billion in February and $56.7 billion in January.
At the same time, futures markets suggest that if the Fed takes any action in the coming months, it will be a rate hike to keep inflation in check, which would also boost the greenback.
Right now, investors are pricing in a scenario in which the central bank leaves interest rates unchanged at 2% during the summer, and a better than 50-50 chance it will raise rates by a quarter of a percentage point when policymakers rendezvous at the end of October.
What's more, most eligible Americans still have not received their economic stimulus check, which could provide a much-needed shot in the arm to both the U.S. economy and the dollar.
But others say it's uncertain whether the economic stimulus checks will be enough to heal the U.S. economy.
"We don't know if the stimulus checks will be a Band-Aid that will help the U.S. economy recover," said David Watt, a senior currency strategist at RBC Capital in Toronto. "Until we are clear about that, the U.S. dollar will struggle."
Plus, foreign investors can be a fickle易變的,無常的 bunch, and the difference between U.S. interest rates and other foreign central banks makes the dollar less attractive.
"At the end of the day, yields in the U.S. are far below yields [of other central banks]," said Daniel Katzive, a foreign exchange strategist at Credit Suisse.
So it is highly unlikely that the dollar will return to the levels it was at just a year ago, when 1 euro was worth $1.35 and a single dollar could fetch 120 Japanese yen.
In order for the dollar to get back to those levels, experts say the U.S. trade deficit would have to drastically shrink and the Fed would need to aggressively raise interest rates to combat inflation.
