Traders do not trust the Fed

The Fed raised the interest rate this month by continuing to claim to raise it once more during the year. It seems, however, that traders do not really believe the Fed, at least judged by one graphics.
Interest rates on two-year bonds are traditionally those that respond quickly to the Fed's decisions and expectations of future interest rates.
Although the Fed signaled a further rise in interest rates this year, interest on 2-year bonds did not make any changes. That means, that investors do not believe that we will see any such action from the reserve.

Or as we see - absolutely nothing.
