Is the dollar doomed?

NEW YORK (CNNMoney.com) -- Don't look now. But the dollar is starting to weaken again against the euro, pound and yen, leading some to wonder if its days as the world's No. 1 currency are numbered.

The euro was trading at about $1.406 on Friday morning, near a two-week high. Though the euro is still more than 10% below last summer's all time-high of $1.6037, the dollar's recent sharp slide has some concerned.

On Friday, Chinese officials reiterated calls for a so-called super-sovereign reserve currency that could supplant the dollar. China's opinion has obvious weight considering that it is the largest owner of U.S. Treasurys.

But the talk of the dollar's imminent demise appears, as Mark Twain once wrote, to be greatly exaggerated, according to some currency strategists.

"Talk of moving away from the dollar as a reserve is overblown. There will still be a lot of faith in the dollar in bad economic times," said Dan Cook, senior market analyst with IG Markets in Chicago. "The world is still looking to the U.S. to get out of this turmoil. Most blame the U.S. for getting the world into this mess after all."

Surprisingly, continued economic weakness is probably good news for the dollar because it could lead foreign investors to rush back into the dollar as a safe haven.

Cook said that much of the rise in other currencies has been at the expense of the dollar because it showed that investors were starting to believe that the global economy was on the mend.

In other words, they didn't need the dollar anymore. But Cook said that the dollar could quickly rebound if next week's jobs report for the month of June shows a continued spike in the unemployment rate.

Even though stock market investors cheered the May job report, which showed that the pace of job losses was decelerating, Cook said that investors might not be so forgiving if the official unemployment rate inches closer to the psychologically important level of double-digit status.

The unemployment rate hit 9.4% in May and economists are forecasting a rate of 9.6% for June, according to Briefing.com.

"Next week's jobs numbers could be huge. If the numbers are worse than expected, that could lead to sustained strength for the dollar," Cook said. "Until the U.S. consumer is really back in the game, it will be difficult for a recovery to happen, especially if the unemployment rate is heading toward 10%."

To that end, consumers continue to save more than spend. The government reported Friday that the personal savings rate was 6.9% in May, up from 5.6% in April and the highest level in more than 15 years.

Others think the dollar will bounce back soon simply because, as bad as things may seem in the United States, they're even worse in other parts of the world -- particularly Europe.

In a report earlier this month, currency analysts for Bank of America Merrill Lynch in London wrote that they expect bank writedowns in Europe to lead to a big boost in dollar purchases.

Here's why. Many European banks raised deposits in the United States and by doing so, created liabilities on their balance sheet. That's because a deposit is really a loan to a bank. These banks then used those deposits to try and make a profit by making loans in dollars or purchasing securities in dollars.
