Mortgage rates nudged above 6% in the US recently, stirring jitters among homebuyers. While the war in Iran has grabbed headlines, it's the stubborn climb in interest rates that could really hurt wallets worldwide.
War Fuels Inflation Fears, But Rates Are the Real Pressure
The conflict in Iran has shaken global markets, pushing oil prices higher and rattling inflation expectations. Crude shipments through the Strait of Hormuz have slowed, causing a daily shortfall of roughly 20 million barrels. That supply disruption sent US gasoline prices up by 26 cents per gallon within a week—the sharpest jump since 2025.
Higher oil costs typically ripple through the economy, lifting consumer prices and prompting central banks to reLook at their policy stances. Investors have reacted by demanding higher yields on bonds, which in turn pushes mortgage rates upward. In the US, the 10-year Treasury yield climbed from 3.96% to 4.14% in just a few weeks after military operations began near Iran.
So far, the average 30-year fixed mortgage rate has crept up to 6%, a modest rise from 5.98% last week but still below last year’s 6.6%. Experts say these incremental increases might not wreck buyers’ budgets, but the psychological impact could be significant.
After all, when rates cross the 6% threshold, it feels like a big deal.
“Two hundredths of a percentage point isn’t a deal breaker for buying power,” said Kate Wood, a lending analyst at NerdWallet. “But psychologically, it’s huge.”
Lessons from Abroad: Singapore’s Rate Rise Warning
Halfway across the world, Singapore is facing a similar conundrum.
The Middle East war’s shockwaves have pushed Brent crude prices above US$110 a barrel, stirring fears of inflation and higher borrowing costs. The Singapore Overnight Rate Average (SORA), which sets the benchmark for mortgage rates there, has been on a downward trend for three years but recently showed signs of rising.
Government bond yields with a 10-year maturity increased by 18 basis points in a month, signalling growing pressure on longer-term interest rates. This warning signs are clear: if the conflict drags on, central banks may tighten monetary policy to combat inflation, pushing mortgage rates higher and impacting homeowners and potential buyers alike.
Singapore’s experience during the Russia-Ukraine war offers a cautionary tale. The commonly used three-month SIBOR rate spiked from 0.5% to over 4%, forcing mortgage rates up for nearly two years. Inflation hit 7.5%, oil prices surged to US$120 a barrel, and the local currency weakened. The economic impact was felt across the board.
Australia’s Position: Rate Rises Already Underway
Closer to home, the Reserve Bank of Australia (RBA) recently raised its policy rate by 25 basis points amid global uncertainty. While other major central banks held steady, the RBA’s move reflects concerns over inflation and the need to keep price pressures in check. The cautious tone of other central banks, including the US Federal Reserve and European Central Bank, suggests that rates could remain elevated for some time.
Australian borrowers have already felt the pinch from rising interest rates. Mortgage repayments have increased, squeezing household budgets and slowing the housing market. The RBA’s actions, combined with global inflationary pressures, mean that Australian homeowners and prospective buyers are unlikely to see relief soon.
And it’s not just interest rates. The war’s broader economic effects — uncertainty around investment, delayed hiring decisions, and postponed contracts — add a layer of risk for the economy. This hidden costs of conflict often outlast the immediate price hikes at the pump.
What This Means for Homebuyers
Higher mortgage rates translate directly into more expensive home loans. Even small rate bumps can add hundreds of dollars to monthly repayments. For first-time buyers, this may push homeownership further out of reach. For existing borrowers, it means budget tightening and less discretionary spending.
While some may blame the Middle East conflict for rising rates, the reality is more complex. Central banks are balancing inflation risks and economic growth, adjusting rates accordingly. The war adds fuel to inflation fears but isn’t the only factor driving up borrowing costs.
Investors, meanwhile, are flocking to safer assets amid market uncertainty, pushing bond yields higher. The ripple effect hits fixed mortgage rates, which tend to track Treasury or government bond yields plus a margin.
Homeowners should brace for possible further increases. If oil prices stay high or climb, inflation could stick around longer, forcing central banks to keep rates elevated.
