The U.S. dollar slipped against the Taiwan dollar Wednesday, a mildly negative sign for the greenback and for Taiwan's exporters.

• The dollar drifted lower in Taipei trading, ending near the low end of a narrow day's range.
• Trading volume was modest, suggesting no big move by investors or the central bank.
• A stronger Taiwan dollar squeezes exporters, who earn in dollars and pay costs at home.
• Taiwan stocks fell the same day, led by tech shares, after losses on Wall Street.

Outlook: The currency looks set to keep trading in a tight range unless Wall Street's tech selloff deepens.
