Kristina Peterson and Jon Hilsenrath: The Fed’s [Twist] program is designed to work by taking long-term bonds off the market, nudging investors into riskier assets, such as stocks, that could help boost the economy. The problem is that while the Fed has been snapping long-term bonds off the market, the Treasury Department has been ramping up its issuance of long-term debt to take advantage of historically low long-term rates. Since October 2008, the average maturity of outstanding marketable Treasurys has climbed by nearly 32%, reaching almost 64 months in May, the agency said earlier this month. That’s its highest level in a decade.
