Economists states that the nominal interest should not fall below zero, in this circumstance, If the inflation falls become negative to deflation, then, the real interest rate figure should not smaller than the deflation figure, otherwise, the nominal interest rate will below zero. In this situation, the problem of deflation will occur when the nominal interest is under the zero limits. The real interest rate has to increase to match the increase of deflation. In addition, when the real interest rate increases, people tend to spend less in the economy, it may also cause problem for certain kind of government policy to implement. ...read more.
