Middle East Conflict Sends Shockwaves Through Australian Bond Yields

By John Baxter, Fixed Income Advisor, LWP Capital

Australian fixed income markets have spent much of the first quarter of 2026 grappling with a source of volatility that has little to do with domestic economic data: the escalation of conflict in the Middle East and the closure of the Strait of Hormuz, which together have upended what had been a relatively settled outlook for interest rates and bond yields.

An External Shock With Domestic Consequences

The closure of the Strait of Hormuz, a critical corridor for global oil shipments, sent crude prices sharply higher through February and March, reversing a period of relative energy price stability. That shock arrived just as the Australian economy was already dealing with capacity pressures and inflation running above target, and the combination proved potent.

Higher fuel prices flowed through directly to headline inflation, which hit 3.8% in the year to January, and the RBA has explicitly flagged concern that the energy-driven price impulse could bleed into broader pricing decisions across the economy, entrenching inflation expectations at an uncomfortable level.

Bond Markets Under Pressure

Australian government bond yields have moved sharply in response, with the benchmark 10-year yield pushing up toward and briefly above the 5% mark during the most acute phases of the conflict — a level that would have seemed unlikely just twelve months earlier. Global bond markets more broadly came under pressure through late March, with Asian and offshore markets both experiencing bouts of heavy selling as risk sentiment soured.

“What we’re witnessing is a genuine repricing of geopolitical risk within fixed income, not just equities,” says John Baxter, fixed income advisor at LWP Capital. “Historically, oil shocks of this scale have forced central banks into a difficult trade-off between supporting growth and containing inflation, and bond markets are having to price both scenarios simultaneously.”

The RBA’s Response

The RBA has responded by continuing its tightening cycle, lifting the cash rate twice in early 2026 to reach 4.10% in March, judging that containing the inflationary impulse from the conflict takes priority even amid signs of softening consumer confidence and weaker household spending. RBA Assistant Governor commentary through this period has acknowledged the hit to sentiment from the oil shock while stressing the Bank’s continued focus on returning inflation to target.

Safe-Haven Dynamics and Foreign Demand

Somewhat counterintuitively, the volatility hasn’t deterred international demand for Australian bonds — if anything, it has reinforced it. “Australia’s AAA credit rating and relatively contained fiscal position have made it an attractive destination for global capital precisely because so much of the developed world is dealing with the same inflationary pressures without the same balance sheet strength,” John Baxter observes. “We’ve seen foreign investors remain active participants in new issuance even through the most volatile weeks of the conflict.”

What Investors Should Watch

For Australian fixed income investors, the conflict-driven volatility highlights several considerations for portfolio construction:

• Energy-linked inflation risk cuts differently to demand-driven inflation. It tends to be more sensitive to the resolution of the underlying geopolitical situation than to domestic monetary policy alone, which complicates the usual central bank playbook.
• Duration remains a double-edged sword. Long bonds have underperformed as yields rose, but they also stand to benefit disproportionately if the conflict resolves and growth concerns come to dominate the narrative instead.
• Diversification across the curve has proven valuable, with short and floating rate exposure providing ballast against the volatility experienced further out.

“At LWP Capital, our approach through this period has been to avoid making large directional bets on how the conflict resolves, since that’s genuinely unknowable, and instead focus on portfolio construction that can perform reasonably well across a range of outcomes,” John Baxter says.

Looking Ahead

With the situation in the Middle East still evolving, Australian bond markets are likely to remain sensitive to developments there for some time yet. Investors should expect continued volatility until there is greater clarity on both the conflict’s trajectory and its ultimate impact on global energy markets.
