Most Asian currencies moved little on Friday, while the dollar held on to recent gains as markets hunkered down before a string of central bank meetings this week, most notably the Federal Reserve.Signals on more policy support in China did little to aid weak sentiment, with uncertainty over the Fed’s plans for future rate actions keeping investors shy of any risk-driven assets.The central bank is still widely expected to hike rates by 25 basis points on Wednesday. But whether it will signal more rate hikes this year remains to be seen, given that U.S. inflation is still trending above the bank’s annual target range.The dollar steadied in Asian trade, with the dollar index and dollar index futures hovering around the 101 mark. Both instruments were trading well above a 15-month low hit earlier in July.Focus this week is also on a European Central Bank meeting on Thursday, with the bank set to hike rates by 25 basis points.
