RBNZ stewardship through the 2008-09 and 2020 shocks

Three decades of low, stable inflation did not spare New Zealand from external shocks, and outgoing Governor Graeme Wheeler's September 2017 reflections on his stewardship of the Reserve Bank traced how the inflation-targeting framework itself became the tool for managing both the 2008-09 global financial crisis and the aftermath of the devastating 2010-11 Canterbury earthquakes, periods when the Bank cut its official cash rate aggressively to cushion a sharp but short-lived contraction in output. Wheeler noted that the credibility built up since 1990 gave the Bank room to ease policy hard during those shocks without triggering the kind of inflation-expectations drift that had plagued the pre-1990 era, allowing growth to resume relatively quickly each time. A similar pattern played out after Wheeler's tenure when COVID-19 hit in 2020, with the Reserve Bank cutting its cash rate to a record-low 0.25% and launching large-scale asset purchases, producing another sharp but short dip in GDP followed by a rapid rebound, consistent with the comparatively low-volatility growth profile the inflation-targeting regime had delivered since the framework's founding.
