With the Bank of Japan raising interest rates for the first time in 17 years this Tuesday, ending the global era of negative interest rates, what is the current policy interest rates and inflation situation in major economies around the world? It is not difficult to see that despite getting rid of negative interest rates, the Bank of Japan is still the only country in the world with zero interest rates, and real interest rates are also in a negative range. The huge interest rate difference between Japan and other countries may also be the main reason why the yen did not rise but fell yesterday after the central bank raised interest rates.
