NEW YORK (TheStreet) -- Investors took profits on the U.S. dollar and reassessed their currency outlook on Thursday as minutes from the Federal Reserve's June meeting hinted at indecision over the initial start date for slowing bond purchases. Most economists still believe September will be the start of a slowdown, but the Fed made it clear that employment targets must be hit for that to be the case.The first chart below is of iShares Barclays 1-3 Year Treasury Bond ( SHY) over iShares Barclays 20+ Year Treasury Bond ( TLT). This pair represents the Treasury yield curve. When the price rises, the curve steepens. A steeper yield curve is usually bullish for the economy and equity sectors such as bank stocks. The pair pulled back yesterday and looks to be overbought with regards to both of its uptrend lines. A pullback in the curve could signal further dollar weakness and commodity market strength.
