Asian markets sprang higher on Tuesday as Japanese stocks rebounded and Chinese money rates eased, while the U.S. dollar got a fillip from a report the Federal Reserve would again trim its bond buying next week, according to Reuters. A drop in the yen helped Tokyo's Nikkei rally 1.5 percent and dragged up markets from Seoul to Singapore. MSCI's broadest index of Asia-Pacific shares outside Japan swung round to be 0.5 percent firmer. U.S. stock futures were also pointing higher, with the S&P 500 up 0.4 percent and the Dow 0.5 percent. Investors kept a wary eye on Chinese money markets after the People's Bank of China (PBOC) announced a surprise injection of funds on Monday aimed at curbing a recent spike in rates. The central bank followed up on Tuesday by adding 255 billion yuan ($42.13 billion) to markets, the largest single-day injection since February 2013. "Such a huge injection," exclaimed one trader at a joint-stock bank in Shanghai. "Now we can get through the upcoming Lunar New Year holiday in peace." The move duly pulled the 7-day bond repurchase rate down to 5.53 percent, from 6.60 percent on Monday, and boosted Shanghai stocks 0.6 percent.
