RBNZ Chief Economist Conway says there is reasonable confidence that inflation has not become broad-based and that rate hikes help contain spillovers from an energy shock

Chief economists at smaller central banks have historically served as the intellectual scaffolding for the Governor's decisions, and their framing on second-round effects has tended to preview the committee's internal debate more reliably than its public communications. The specific distinction drawn here, that inflation has not gone broad-based while hikes still contain energy-shock spillovers, is the classic transitory-but-insuring posture central banks in commodity-exposed economies have adopted in past supply-shock episodes: the bank signals willingness to lean against imported price pressure without conceding that core dynamics have turned. In prior episodes of this kind, the sequencing has been a hawkish lean on the front end, followed by a rapid unwind once headline energy prices rolled over, since policy set against a supply shock becomes restrictive precisely as the shock fades. The transmission channel for NZD is the front-end differential against the larger commodity and rate peers, with the curve's pricing of the terminal rate more sensitive than any single release. What is worth watching is whether the next quarterly inflation print confirms the not-broad-based claim, and whether other RBNZ officials echo the framing, since convergence among officials has historically preceded the committee's median view.
