NEW YORK ( TheStreet) -- Markets have been awaiting Federal Reserve Chairman Ben Bernanke's testimony before Congress on Wednesday.
Speculation for hawkish and dovish stances both have validity, which has caused volatile trading on thin volume. With the consensus still that bond purchases will slow this fall, Bernanke's perception of economic data over the past few weeks will determine whether September is still the right time to rein in easing.
The first chart below is of PowerShares DB US Dollar Index Bullish (UUP) over CurrencyShares Swiss Franc Trust (FXF). This pair crosses the U.S. dollar verus the Swiss franc, a traditional safe-haven currency.
The dollar has given up positioning at its yearly highs, due to a dovish tone from the Fed over the past few weeks. Bernanke has reiterated that tighter policy depends on better economic data. His dissatisfaction with labor markets, albeit prior to the latest jobs report, led investors to believe quantitative easing was still on the table for an extended period of time.Bernanke's testimony should determine whether the Fed is pleased with improvements in data seen the past few weeks, thus giving more weight to the idea of a slowdown in bond purchases starting in September. The next chart is of iShares Barclays TIPS Bond (TIP) over iShares Barclays 7-10 Year Treasury (IEF). This pair measures inflation expectations through Treasury market movements. As inflation fears have subsided and become largely nonexistent, assets such as Treasury Inflation-Protected Securities and gold have weakened. The strong downtrend has been present for most of 2013. (SHY) over iShares Barclays 20+ Year Treasury Bond (TLT). This pair measures the steepness of the Treasury yield curve. As the price action advances and long-term rates outpace short-term rates, the curve steepens. And as investors have priced in a September end to quantitative easing, long-term Treasuries have seen a vast selloff. The uptrend beginning in mid-May signals the unrelenting cycle out of Treasuries. The pair has continued to push higher, even with steep pullbacks to the trend line over the past two months. Volatility has ensued in assets dependent on rates. Regional banks have seen wide price swings, as have stocks tied to housing and mortgage lending. Bernanke's testimony will determine whether this pair brakes the trend. If it does and the curve flattens, assets tied to rates will become even more volatile.
