Stocks slide as oil nears US$95 and bond yields surge — what should investors watch now?
Global markets have started September under pressure as renewed US-Iran attacks push oil towards US$95 a barrel and revive fears of another round of interest-rate increases.
The shift comes after a strong August. The Nasdaq gained 3.9% during the month, the S&P 500 rose 2.6%, and the Dow advanced for a fifth consecutive month. In Australia, the ASX 200 reached a record 9,296.7 in early August before retreating below 9,000 this week.
Investors are now questioning how long those gains can survive a fresh energy shock. Brent crude has rebounded from below US$80 in early August to around US$95, while markets are pricing approximately a 70% probability that the Federal Reserve and Reserve Bank of Australia will both raise rates in September.
The pressure has already spread beyond shares. Gold has retreated from its August highs, Bitcoin has fallen towards US$78,000, and the US dollar has strengthened. Energy stocks are one of the few clear beneficiaries as higher crude prices improve the revenue outlook for producers.
For Australian traders, the next move could be unusually divided. Further conflict may support Woodside, Santos and oil prices while weighing on the Australia 200, Nasdaq 100 and consumer-facing shares. A credible reduction in hostilities could reverse those positions quickly.
A strong August has given way to a difficult September
September has historically been the ASX 200’s weakest month. Since 1980, the index has recorded an average September decline of 0.42%. Total-return data since 2001 show an average fall of 0.65%, with the market finishing higher only 44% of the time.
The month has begun with several immediate pressures that were largely absent during August’s rally: oil near US$95, renewed military escalation and rising expectations for interest-rate increases in both Australia and the United States.
Contracts for Difference (CFDs) allow eligible traders to take a long or short view on selected indices, commodities, cryptocurrencies and shares without owning the underlying asset.
Further escalation could support a long view on oil and a short view on rate-sensitive indices. A credible diplomatic breakthrough could favour the reverse as crude loses part of its war premium and investors return to growth assets.

Oil near US$95 has changed the inflation outlook
Fresh US strikes on Iranian military targets near the Strait of Hormuz have been followed by further retaliation from Tehran, producing the most serious exchange between the two sides since July.
The escalation has pushed Brent to a five-week high near US$95. The move extends a much larger recovery from the US$79.36 reached in early August, when investors briefly expected diplomacy to restore safer shipping through the Strait.
Higher crude prices feed into petrol, freight, aviation and manufacturing costs. Companies must either absorb those expenses through lower margins or pass them on to customers. Neither outcome is particularly supportive for the wider equity market.
A move above US$100 would intensify the pressure. An agreement that restores regular tanker traffic could push crude back towards the mid-US$80s and change the market outlook just as quickly.
Technology shares have the most to defend
Technology companies enter this period after delivering some of the market’s strongest August gains.
The sector still has substantial earnings support. Nvidia reported quarterly revenue of US$96.2 billion, more than double the prior-year figure, and forecast US$108 billion for the current quarter. Its result confirmed that spending on AI data centres, chips and networking remains exceptionally strong.
The difficulty is that good earnings must now compete with worsening macro conditions.
High-growth companies typically carry more demanding valuations because investors expect profits to expand for several years. When interest-rate expectations rise, the market becomes less willing to pay heavily for those future earnings.
That does not mean the AI trade is broken. It means the gap between companies delivering real profit growth and those trading mainly on enthusiasm may become more important.
Gold is being tested as a safe haven
Gold has also struggled to benefit from the renewed fighting.
The metal remains higher over the past month, but it has fallen from its August peak to around US$4,325 an ounce. The stronger US dollar and renewed rate-hike expectations have outweighed some of the demand normally created by geopolitical uncertainty.
Further military escalation could bring safe-haven buyers back, particularly if investors become more concerned about shipping, energy infrastructure or wider regional involvement. But if that escalation primarily drives the US dollar and interest rates higher, gold may remain under pressure.
Australian gold miners face the same conflict. Northern Star, Evolution Mining and Newmont can benefit from a sustained rise in bullion, but their shares can weaken when gold falls even if the original geopolitical risk remains unresolved.
What could deepen or reverse the pressure?
The immediate outlook rests on three connected catalysts.
Shipping and military developments
A further attack on a tanker, port or export facility could push Brent above US$95 and bring US$100 back into focus. Iran’s ability to restrict traffic through Hormuz remains the central risk because the Strait previously handled around one-fifth of global oil and LNG shipments.
A credible agreement would require more than a commitment to hold talks. Markets will look for safer shipping routes, sustained tanker movements and evidence that insurance and freight conditions are returning towards normal.
Federal Reserve and RBA expectations
US employment and inflation data will shape expectations before the Federal Reserve’s September meeting. Stronger figures combined with expensive oil would reinforce the case for another increase, while softer data could reduce the pressure.
Australian inflation, employment and RBA commentary will play a similar role locally. Markets have moved quickly towards expecting a September increase, leaving room for a reversal if domestic data weaken.
Whether equity support levels hold
The ASX 200’s return below 9,000 has erased its August breakout. A sustained recovery above that level would suggest buyers still see value after the pullback. Further weakness would put the earlier 8,500–9,000 trading range back into focus.
US technology shares face a comparable test after their strong August. If the Nasdaq holds most of its monthly gain despite higher oil, earnings may still be providing meaningful support. A broader breakdown would show that the macro pressure is overwhelming company fundamentals.
Trading both sides of the market with CFDs
The current environment can produce gains in one market and losses in another from the same headline.
An escalation around Hormuz may push oil higher while weighing on technology, consumer and travel shares. Negotiations may send crude lower while supporting the Nasdaq 100 and other rate-sensitive markets.
Mitrade gives eligible Australian traders access to selected CFDs across:
Brent and WTI crude oil.
Gold and other commodities.
The Australia 200, Nasdaq 100 and S&P 500.
Selected Australian and US shares.
Bitcoin and other cryptocurrencies.
CFDs allow long positions when a trader expects a market to rise and short positions when they expect it to fall. A trader expecting further escalation could take a long view on oil or a short view on an exposed index. Someone expecting a diplomatic breakthrough could form the opposite view.
Short positions do not require ownership of the underlying instrument, but the risk remains substantial. An unexpected ceasefire, military strike or central-bank statement can reverse prices rapidly, and leverage magnifies losses as well as gains.
Mitrade also provides:
Stop-loss and take-profit orders to define planned exit levels.
Pending orders around selected support, resistance or breakout prices.
Real-time charts and mobile access.
AUD account funding, with margin and profit or loss displayed in Australian dollars.

CFDs are complex instruments and carry a high risk of losing money rapidly due to leverage. Traders should understand how CFDs work and consider whether they can afford the risk of losing money.
Start trading global market volatility in three simple steps
1. Why have global markets come under pressure?
Renewed US-Iran attacks have pushed Brent crude towards US$95 and increased concern that inflation will remain elevated. Markets have also raised the probability of further interest-rate increases in the United States and Australia.
2. Can traders take a view if markets continue falling?
CFDs allow eligible traders to take short positions on selected indices, commodities and shares without owning the underlying instrument. Losses occur if the market rises instead, and leverage can magnify the result.
3. What could help shares recover?
A credible reduction in US-Iran hostilities, safer shipping through the Strait of Hormuz, lower oil prices or economic data that reduces expectations for further interest-rate increases could support a recovery.
