The dollar index, which measures the greenback against six major peers, was down 0.07 percent to 96.9680 at 3:00 p.m. (2000 GMT).
Two-year bond and three-year bond yields surpassed the five-year yield for a second day on Tuesday, according to Reuters data, creating a inversion of the yield spread, which is normally viewed as a precursor of an economic downturn.
Over the past five decades, an inversion of yield spread between the two-year and 10-year notes appeared ahead of every recession in the United States. Analysts cautioned that the latest inversion between short-dated and long-dated bonds signaled market expectations that U.S. economic growth will slow down.
The recent broad sell-offs in the stock markets have prompted some investors to turn to the comparatively less risky U.S. Treasury bonds and also increased demands for the greenback as a safe-haven currency because of its high liquidity.
However, analysts said as traders grew worried about sagging U.S. growth, longer-dated Treasury bond yields have been sharply weighed down.
