Rate markets have already pared back conviction on a July move, with hike odds slipping from above 80% a week ago to a range now clustering around the high 60s to 70%. The retreat in crude toward the high USD60s a barrel, down sharply from the roughly USD101 assumed in the RBNZ's May projections, is the main swing factor, easing near-term fuel price and CPI pressure. That leaves two-sided risk into July 8: a soft landing in oil could hand the RBNZ cover to slow down, while a weaker NZD and still-anchored tightening bias argue for following through. Curve positioning suggests traders are not fully pricing a downside surprise, leaving room for volatility around the decision either way.---RBNZ tipped to hike 25bp on July 8 despite Middle East ceasefire and sliding oil prices, though market-implied odds have eased to under 70% from over 80% a week ago.

Tightening cycle still in effect, pared backSummary:RBNZ widely expected to raise the cash rate 25bp on July 8 and retain its tightening biasCrude has fallen to around USD68 a barrel versus the USD101 assumed in the RBNZ's May review, easing fuel and CPI pressureLabour market data have come in weaker than the RBNZ anticipated, though broadly consistent with May projectionsNew Zealand dollar weakness is seen as adding to inflation pressure, reinforcing the case to hikeMarket-implied probability of a July hike has eased to around 70%, down from over 80% a week earlierBank sees risk skewed toward more tightening than currently priced for the rest of 2026The Reserve Bank of New Zealand is widely expected to raise the official cash rate by 25 basis points at its July 8 review, even as a Middle East ceasefire and a sharp pullback in oil prices complicate the case for further tightening. According to BNZ Research, the central bank will likely maintain its tightening bias while leaving the door open on the pace and timing of subsequent moves, given the Monetary Policy Review format does not include an interest rate track.The key swing factor is oil. Dubai crude has dropped to around USD68 a barrel, well below the roughly USD101 the RBNZ pencilled in for its May Monetary Policy Statement, when it cited the Middle East conflict as having materially altered the inflation and growth outlook. That decline would normally argue for a lighter policy touch, but analysts note the RBNZ can sidestep judgment calls on whether the ceasefire holds simply by using the oil futures strip as its working assumption, much as it did in May.Offsetting the oil relief, labour market data have come in softer than the RBNZ had assumed, and near-term inflation is tracking lower than anticipated. Even so, a weaker New Zealand dollar is seen as a partial counterweight, having fallen more than a year to fresh lows on a trade-weighted basis, which adds to imported inflation risk. Analysts also argue the RBNZ would risk credibility damage if it failed to deliver a hike that has been well flagged, given half the Monetary Policy Committee wanted to move at the prior meeting and both camps signalled comfort with further increases this year.Market pricing has softened accordingly. Implied odds of a 25 basis point hike have eased to around 70%, down from more than 80% a week earlier, reflecting the broader retracement in global tightening expectations since the ceasefire. Still, with domestic data between now and the review seen as unlikely to shift the committee's thinking, attention is turning to offshore drivers, including US payrolls and the ECB's Sintra forum, as the next major swing factors for rate expectations heading into the decision.
