A New Zealand ten dollar note sits underneath a United States one dollar bill in the window of a currency exchange teller in Sydney, Australia, March 10, 2016. New Zealand's central bank unexpectedly cut interest rates to a record-low 2.25 percent on Thursday, triggering a slide in the local dollar and sparking talk of a global currency war as countries seek to revitalise their economies in a world of slow growth.
