The trust of bond investors, in U.S. Federal Reserve (Fed) Board Chair Janet Yellen's remarks about inflation, seems to have declined. Although Yellen underscored last week that the Fed expects to be closer to the inflation target of 2 percent, the expectations of markets for the short and long-term price rises are at their lowest levels since 2009. This is crucial in that such anticipation has continued despite the fact that oil prices have recovered 20 percent since the previous month.

Speaking to Bloomberg HT, Priya Misra, director of global interest rate strategy of TD Securities in New York City, said: "We have spent many years with expansionary monetary policy; thus, I think markets have lost confidence in the Fed. You do not see [that] policy really affects inflation."

Yellen added that along with the declining oil prices, the strengthening dollar has also contributed to the slowing pace of inflation - attributed to the impact of the strong dollar on import prices. Monetary incentive practices of international central banks have apparently been complicating the Fed's policymakers' efforts to increase the inflation rate as well. Following the Fed's decision in September, traders speculate that interest rates will increase by merely 0.71 percent by the end of 2016. This number corresponds to almost half of the Fed's policymakers' forecast median. The difference between the expectations is the highest since the beginning of 2014.
