AUD and NZD wobble as oil jumps

The Australian dollar and New Zealand dollar weakened on Monday after renewed U.S. strikes on Iran sent oil prices higher, increasing risk aversion and pressuring commodity-linked currencies, officials said.

Kiwi inflation report in focus

The kiwi is headed into a key domestic inflation release that traders expect will influence the Reserve Bank of New Zealand's near-term tightening path, officials said. The wire noted the report could help decide another near-term rate hike, and market participants are parsing whether price pressures remain broad-based or concentrated in specific categories.

Oil's jump amplified the move in FX by raising concerns over a growth–inflation trade-off for commodity importers and exporters, officials said. AUD typically tracks energy and metals prices through commodity channels; a sustained oil rise can tighten Australian trade balances and nudge rates expectations. NZD sensitivity to the upcoming inflation print adds a domestic layer to the external shock.

Volatility in Asian FX and higher oil risk premiums could widen cross-asset risk aversion into local rates and equities, officials said. Portfolio flows into safe-haven currencies may amplify moves if additional strikes occur.

Investors will focus on the New Zealand inflation release due on July 22, 2026, and any follow-up geopolitical developments over the next 48 hours for cues on currency and rate-market positioning.
