Interest rates: The Bank of Japan and the government have unleashed an ultra-loose monetary policy, heavy government spending, and economic reforms to try to sustain solid growth and help Japan break free from prolonged deflation — a period of falling prices — that tends to discourage spending and investment.

— RESERVE BANK OF AUSTRALIA
Interest rates: Has cut its benchmark interest rate to a record low 2.5 percent because of slower growth and high unemployment. The 2.5 percent policy rate is the lowest since the central bank was established in 1960.
