The New Zealand dollar spiked higher against its major trading partners in the Asian session on Wednesday, as New Zealand's central bank left its monetary policy unchanged and agreed to cut its interest rates further if required as the economic outlook remains highly uncertain.

The Monetary Policy Committee of the Reserve Bank of New Zealand decided to keep the Official Cash Rate at 0.25 percent and the Large Scale Asset Purchase at NZ$100 billion. The Funding for Lending programmes were also kept unchanged.

The committee agreed to retain its current expansionary monetary setting until consumer price inflation will be sustained at the 2 percent target, and that employment is at or above its maximum sustainable level.

The MPC said it is prepared to lower the benchmark rate if required.

The committee observed that short-term data continues to be highly variable as a result of the economic impacts of COVID-19.

Over the medium-term, the outlook remains highly uncertain, determined in large part by both health-related restrictions, and business and consumer confidence, the MPC said.

The currency was further underpinned by rising risk appetite, as the pick up in U.S. consumer prices was not swift enough to necessitate a policy change by the Federal Reserve.

U.S. bond yields eased as the government's auction of 30-year bonds was met with strong demand.
