Australia's central bank raised the key interest rate to a 15-year high on September 29 to curb inflation, which the government blamed on the prolonged war in the Middle East. The Reserve Bank of Australia lifted its cash rate 25 basis points to 4.6 percent, it said, citing a broadening conflict in the Middle East and high global energy prices.
