MPC Morning Call — 2nd September 2026: US Strikes on Iran Send Oil Surging as Bond Yields Hit Multi-Decade Highs
2 September 2026
Wall Street sold off to close out August as fresh US airstrikes on Iran and tanker attacks in the Strait of Hormuz sent WTI crude surging 5.9% to $90.82 a barrel. The S&P 500 fell 0.71% to 7,631.47 while the Nasdaq dropped 1.03% to 26,099.77, dragged by a 2.1% slide in semiconductor stocks. Bond yields spiked across the globe, with the US 10-year hitting 4.79% and Japan’s 10-year breaching 3% for the first time since 1996. ASX 200 futures point to a weaker open, down 79 points.
Summary
Geopolitics and inflation fears collided overnight. The US launched fresh strikes on Iranian targets while separate tanker attacks at the entrance to the Strait of Hormuz sent oil prices sharply higher. Brent crude surged 7.9% to $95.36 and WTI jumped 5.9% to $90.82, pushing crude back towards triple digits. The S&P 500 dropped 0.71% to 7,631.47, the Nasdaq fell 1.03% to 26,099.77, and the Dow shed 0.79% to 52,766.93. The SOX semiconductor index lost 2.1% with every constituent in the red. Gold fell 2.4% to $4,330 as surging bond yields pulled capital toward Treasuries. The US 10-year yield climbed to 4.79%, its highest since January 2025, while Japan’s 10-year breached 3% for the first time since 1996. Fed rate hike expectations jumped to around 68% for September, up from 39.6% a week ago. JOLTS job openings came in at 7.271 million, slightly below the 7.33 million consensus. Dell surged 9% after hours on a strong AI server outlook.

Equities: Semis Sink and Energy Rallies as August Closes on a Stumble
Wall Street limped into September. The S&P 500 dropped 0.71%, the Nasdaq fell 1.03%, and the Dow shed 0.79%. Not catastrophic, but a clear signal the geopolitical risk premium is back.
Semiconductors bore the brunt. The SOX index fell 2.1% with every single constituent finishing lower. Energy was the obvious winner, rallying hard on the oil spike, but outside of that pocket it was red across the board. Eight of eleven S&P 500 sectors finished lower.
After hours, Dell jumped 9% on an AI server outlook that beat expectations. Server order backlog grew for the fifth consecutive quarter. We think the market is overweighting the geopolitical noise and underweighting the capex cycle right now.

Oil ripped higher. WTI surged 5.9% to $90.82 and Brent jumped 7.9% to $95.36 after fresh US airstrikes on Iranian targets and separate tanker attacks at the entrance to the Strait of Hormuz. The pattern keeps repeating: escalation, oil spike, brief calm, then another escalation.
Russia added to the supply-side pressure by cutting its 2026 production forecast to the lowest since 2009. When both OPEC+ discipline and Middle Eastern supply disruption are tightening at the same time, the floor under oil prices gets very difficult to break.
For Australian investors, this matters more than most realise. Higher oil feeds directly into transport costs, which feeds into CPI, which feeds into the RBA’s rate calculus. With Q2 GDP data dropping today at 11:30am, we’re about to get a read on how the domestic economy is holding up under that pressure.
| Commodity | Daily | 5-Day |
|---|---|---|
| WTI Crude | +5.04% | +10.76% |
| Gold | -2.71% | -5.73% |
| Silver | -3.79% | -4.76% |
| Copper | -2.31% | -0.87% |
| Iron Ore | +0.69% | +1.02% |
| Coal | +2.84% | — |
| Uranium (URA) | -3.45% | -8.55% |
| Bitcoin | -1.98% | -1.16% |

Bonds & Rates: Yields Hit Levels Not Seen in Decades
The US 10-year yield climbed to 4.79%, its highest since January 2025. But the bigger story is Japan, where the 10-year breached 3% for the first time since 1996. Thirty years.
The US 30-year average yield is now at 4.96%, closing in on 2004’s 5.03% level. Fed rate hike expectations have moved sharply. September hike odds jumped to roughly 68% from 39.6% a week ago. The oil shock is the accelerant. Higher crude pushes up headline inflation expectations, making it very difficult for the Fed to stand pat even if the underlying economy is softening.
JOLTS job openings came in at 7.271 million, a touch below the 7.33 million consensus, suggesting the labour market is cooling modestly. But with oil doing what it’s doing, the Fed is watching CPI, not JOLTS.

ASX 200 futures are pointing to a weaker open, down 79 points or 0.9% to around 8,988. Energy names should see a bid given the oil move, but the broader market will be dealing with higher yields, geopolitical uncertainty, and a Fed that looks increasingly likely to hike.
The big domestic event is Q2 GDP at 11:30am AEST. Given the oil-driven inflation squeeze and the RBA’s hawkish lean, this number matters a lot. A soft print might give the RBA cover to hold, but a strong one could tip the balance towards another hike.
| Event | Time (AEST) | What to Watch |
|---|---|---|
| Australian Q2 GDP | 11:30am | Consumer spending resilience, govt spending contribution |
| US ISM Manufacturing | Overnight | Below 50 = contraction; prices-paid subindex key given oil |
| US Earnings: Palo Alto, Dell, MongoDB, GitLab | After hours | Dell already beat; Palo Alto for cybersecurity read |
| VIX | 16.31 | Creeping higher but below 20; orderly sell-off for now |
| BTC / AUD | $77,239 / 0.7142 | Both reflecting risk-off tone but no panic |
