The NZ dollar lost ground against its major counterparts in the Asian session on Wednesday, after the Reserve Bank of New Zealand kept its benchmark interest rate unchanged and expanded the asset purchase programme unexpectedly, citing concerns about the economic disruption caused by the pandemic.

The Monetary Policy Committee of the Reserve Bank of New Zealand decided to expand the Large Scale Asset Purchase programme up to NZ$100 billion and also agreed that a package of additional monetary instruments must remain in active preparation.

Additional stimulus could include a negative rate, the direct funding of retail bank lending and purchases of foreign assets.

The central bank retained its key interest rate at 0.25 percent.
