Asian shares were mixed on Tuesday in a day of central bank focus and with eye sharpened on the review of interes rates by the Federal Reserve this week. The Nikkei 225 rose 1.33%, while the Shanghai Composite was down 2.20%. The S&P/ASX 200 eased 1.22%. Earlier, the Bank of Japan, as expected, held base monetary policy steady at its latest review while repeating that core CPI views remain flat. The BoJ asset program focused on government bonds is now ¥80 trillion annually. Ahead, BoJ Governor Haruhiko Kuroda holds a news conference at 1530 (0630 GMT) to explain the board’s decision. Minutes from the September central bank monetary policy board meeting in Australia showed concern over the impact on domestic growth of the economic slowdown in China. “Members noted that the Chinese authorities had for some time been selling foreign exchange reserves to prevent the RMB from depreciating against the US dollar in the face of significant capital outflows,” the RBA minutes said. “This contrasted with the experience in the previous decade, during which foreign reserves had been accumulated to limit the appreciation of the RMB in the face of capital inflows. Members noted that it was not clear which assets the Chinese authorities had sold as part of the recent intervention nor which assets were being bought by those taking capital out of China, but given the potential size of these flows, their effects on asset markets could be large.” Overnight, U.S. stocks were lower after the close on Monday, as losses in the Basic Materials, Oil & Gas and Consumer Services sectors led shares lower. At the close in NYSE, the Dow Jones Industrial Average fell 0.38%, while the S&P 500 index lost 0.41%, and the NASDAQ Composite index lost 0.34%.
