Just a few months ago, investors were eagerly gobbling up two-year notes yielding below 0.25% because of Europe's debt crisis. Now that Greece got its loan approved and the situation seems to be stabilizing, the US government can't seem to work up that type of interest even when offering a 0.31% yield at this afternoon's two-year note sale. Upbeat US economic readings are also reducing the demand for Treasurys. Analysts say the one major factor keeping the market supported is the Fed's clear message that it intends to keep the policy rate near zero through at least late-2014.
