The Reserve Bank of New Zealand, sometimes seen as global monetary policy's "canary in the coal mine," takes center stage in the Asia and Pacific region on Wednesday when it delivers its latest interest rate decision. U.S. Treasury yields inched up slightly on Tuesday after the bond market absorbed a $42 billion auction of seven-year paper without much trouble. All in all, a quiet session on Tuesday that is unlikely to give much direction for Asia on Wednesday, which means even more attention falls on the RBNZ's rate decision.
