RBNZ assistant governor Silk said Friday the bank has not yet seen medium‑term inf pressures but is ready to act aggressively if second‑round effects materialize. All options remain under consideration, including a more aggressive 50bp hike; the key issues are timing of rate increases and how much weaker growth will offset medium‑term inf. If incoming data show second‑round effects emerging, the 50bp option would be retained; conversely, data could justify holding rates unchanged.
