The New Zealand dollar rose against the greenback with investors' appetite for higher yielding, or riskier, assets buoyed by speculation that the US Federal Reserve will act to boost the world's biggest economy.
The New Zealand dollar recently traded at 82.25 US cents, up from 82.11 cents yesterday, and rose to 72.12 on the trade-weighted index of major trading partners' currencies from 72.03 previously.
Global markets snapped recent declines amid hopes of further stimulus from the US central bank as it began its extended two-day Federal Open Market Committee meeting in New York.
The market is betting that the Fed will implement 'operation twist', a re-profiling of US government debt to bring long-term rates down and leave the short end of the curve unchanged, a move supportive of business and house lending.
In late afternoon trade, the Standard & Poor's 500 Index rose 0.3 per cent to 1,207.21, and Europe's Stoxx 600 closed 1.8 per cent higher at to 229.10.
