U.S. interest level swap narrowed to lowest since March 2010

Interest rates swaps in the U.S. declined on Monday falling to the lowest level in more than a three-year period relative to Treasuries as investors sought riskier assets outside of government debt on speculation that Fed's Chairman Janet Yellen keep borrowing costs low. The 5-year bond and similar-maturity swap gap narrowed to 9.25%, the lowest since March 2010.
