Fears that the Federal Reserve could raise interest rates sooner rather than later sent Asian indices spiraling on Wednesday, with Sydney, Hong Kong and Taipei markets hitting fresh lows.

U.S. shares tumbled overnight, taking their cues from rising Treasury yields overseas and domestically, after suggested that investors' expectations for rate hikes lag those of the Fed. The Dow Jones Industrial Average ended down 0.6 percent while the S&P 500 fell 0.7 percent. The Nasdaq lost 0.9 percent.
