Regardless of the central bank interest rate the free market interest rate will increase if inflation rises to compensate for the lost value of the money invested. In short if inflation rises interest rates tend to rise anyway regardless of the central bank rate. There is a whole school of economic thought called Austrian Economics which states the interest rate should not be altered by a central body but follow the natural rate set by banking institutions to reflect the risk or cost of borrowing. The Monetarists believe the interest rate should be altered to hit the inflation target which I think has been set to help with long term financial forecasting, read the article below. http://morganisteconomics.blogspot....-greatest-contribution.html?q=milton+friedman Regardless there are other methods of controlling inflation that have been used including fiscal policy, pension policy and other techniques of monetary policy.

In regards to the original question, the easy answer is yes and they have been for decades, ever since Reagan took office after interest rates went crazy during the Carter administration. The formula for calculating inflation was changed and presto, perpetually low to no inflation. The current formula doesn't allow for the inflation rate to stray outside the 1.75 - 2.25% range, with perhaps a rare exception. Along with employment, GDP, crime, etc,... really none of the numbers the Fed puts out,... are an actually true or accurate representation of reality. But it doesn't matter, because perception is everything. As President Nixon said, if the people(referring to the masses), see it on TV they will believe it.

In the United Kingdom you can get a type of pension called a SSAS Small Self Administered Scheme that enables you to borrow or buy into your business to support it using your pension fund, it is however only available to company directors or senior managers. There is a lot you can do with pensions, which gives you a way out of the problems in the economy. See my work that has been successful in the United Kingdom as a contingency against those problems in the United States, if you are interested in my work you can view it at morganist economics.
