NEW YORK ( ETF Expert) -- Who are these folks who keep insisting that the Federal Reserve will slow its bond purchases in September? Unless I've missed something, the press releases concerning Fed policy have explicitly stated that the central bank will maintain its zero percent interest rate policy for as long as the U.S. unemployment rate remains above 6.5% and price inflation remains below 2.5%.Granted, quantitative easing (QE) is merely a component of the Fed's efforts to suppress intermediate- to longer-term interest rates. What's more, Chairman Ben Bernanke has made a distinction between purchasing government debt at a slower pace and terminating the program. Nevertheless, who genuinely believes that unemployment is falling at a rapid enough clip to warrant a change in direction? Who actually sees the Fed's inflation measure rising at a fast enough pace to justify a policy modification? Last but not least, why would Bernanke want to rock the apple cart in any shape or form prior to his January departure? Perhaps ironically, the bond market has already thrown a tantrum at the mere suggestion that QE might be on its way out, albeit slowly. The 10-year yields have jumped a full percentage point in anticipation of a September change. It follows that the Fed can probably sneak a modest reduction in its money printing and debt repurchasing without sending yields skyrocketing. Nevertheless, I doubt the Federal Open Market Committee will have the wherewithal to be aggressive at the same moment that Congress is fighting over the debt ceiling/government funding. In other words, the greater risk to investors may be in holding firm to the belief that bond yields are going to soar over the next six months. Yields may waffle between 2.5% and 3%, but they're not going to move higher than that. In contrast, there are many possibilities that could lead to 10-year treasuries yielding 2%-2.25% by year's end. That's right, lower. Falling yields (rising bond prices) could occur due to political impasses, renewed safe haven seeking or the Fed simply staying on its present path. Even if the Fed attempted to begin exiting from its third round of QE in September, a long-awaited stock market correction of sufficient severity (10%-20%) and swiftness (weeks, not months) would usher in QE4. Prominent Democrats simply won't permit any form of austerity to damage congressional prospects in the November 2014 elections.
