LONDON — It's just straws in the wind so far. India's Ministry of Culture announces that foreign tourists can no longer pay in dollars when visiting the Taj Mahal and other heritage sites; they have to pay in good, hard rupees. Iran and Venezuela call for a joint OPEC statement on the weak dollar, and Saudi Arabian Foreign Affairs Minister Saud Al-Faisal warns that any public reference to the dollar's problems could cause the troubled currency to "collapse." Rap star Jay-Z's latest video shows our hero flashing a wad of euros, not dollars.

Only straws in the wind, but all in the past couple of weeks. For the majority of Americans who do not travel abroad, the only visible effect so far of the dollar's steep fall has been higher fuel prices at the pump. The Chinese imports that fill the big-box stores still cost the same, because the Chinese yuan is still pegged to the dollar. But that may be about to change, along with many other things.

At the beginning of 2003, one euro bought one dollar. Eighteen months ago, it bought $1.20. Now it is pushing $1.50, and there is no reason to think that it will stop there.
