NEW YORK, Aug. 12 (Xinhua) -- The U.S. dollar weakened in late trading on Wednesday as market participants were cautious following a stalemate over a new coronavirus relief bill in the country.

The dollar index, which measures the greenback against six major peers, decreased 0.20 percent at 93.4457.

In late New York trading, the euro rose to 1.1783 U.S. dollars from 1.1745 dollars in the previous session, and the British pound was down to 1.3026 dollars from 1.3062 U.S. dollars in the previous session. The Australian dollar increased to 0.7162 U.S. dollar from 0.7151 dollar.

The U.S. dollar bought 106.85 Japanese yen, higher than 106.65 Japanese yen of the previous session. The U.S. dollar decreased to 0.9122 Swiss franc from 0.9173 Swiss franc, and it decreased to 1.3253 Canadian dollars from 1.3282 Canadian dollars.

Traders grappled with the uncertain fate of further coronavirus stimulus as U.S. lawmakers were still arguing over the design of the new package.

On the data front, U.S. consumer price index increased 0.6 percent in July, matching the rise in June, with gasoline accounting for a quarter of the gain, the Labor Department reported Wednesday.
