SPX: S&P 500 Futures Slide as Traders Almost Fully Price In a Rate Hike This Week. What to Watch.

Fresh attacks on Saudi infrastructure sent oil higher and global equities lower. Ahead is a week packed with central-bank decisions, including potential rate increases from both the Fed and Bank of Japan.

🌏 Selling starts from Asia

• S&P 500 futures fell roughly 0.5% early Monday, while Nasdaq 100 futures dropped around 1.1%. The retreat followed a difficult week in which the S&P 500 lost 0.8%, the Nasdaq fell 0.7% and the Dow suffered its sharpest weekly decline since March.
• Asian markets provided the first look at this week’s risk appetite. Japan’s Nikkei 225 dropped 1%, while South Korea’s Kospi lost 2.1% as technology and AI-linked shares retreated.
• Higher oil prices are particularly uncomfortable for energy-importing economies because they raise costs while draining money from consumers and businesses.

🛢️ Oil reconnects with inflation

• Brent crude climbed more than 2% to around $107.50 a barrel, while WTI rose above $102. The immediate catalyst was the shutdown of Saudi Arabia’s East-West pipeline after a drone attack, potentially disrupting exports equivalent to as much as 4% of global oil supply.
• Oil affects the S&P 500 well beyond its energy sector. Producers may benefit, but airlines, logistics companies, chemical manufacturers and retailers face higher costs.
• More expensive fuel can also lift consumer inflation, leaving households with less money for everything that does not arrive through a pipeline.

🏦 Two central banks enter the ring

• Last week’s big news: US consumer prices rose 0.4% in August and 3.4% from a year earlier. Core inflation, which excludes volatile food and energy prices, increased 0.3% — slightly above forecasts.
• Markets now assign an 86% to 87% probability to a quarter-point Fed rate increase this week. Goldman Sachs abandoned its previous call for no change and now expects the Fed to raise rates.
• The bank’s reasoning partly reflects market pricing: once traders become overwhelmingly positioned for a hike, holding steady can itself produce volatility. Expectations sometimes help write the decision they are anticipating. Reflexivity, anyone?
• The Bank of Japan may also lift rates to 1.25%, while the European Central Bank tightened policy last week. The yen has gained about 4% this month, potentially pressuring Japanese exporters and carry trades — strategies that borrow cheaply in yen to buy higher-return assets elsewhere.

📊 The cross-market checklist

• Treasury yields remain central to the equity outlook. The 10-year yield is near 5%, while the 30-year recently climbed above 5.3%. Higher yields raise borrowing costs and reduce the present value of future earnings, making richly valued technology shares particularly sensitive.
• The dollar was edging higher this morning, but the yen remained near a seven-month peak. Gold faces competing forces: geopolitical tension supports demand for safety, while rising yields increase the opportunity cost of holding an asset that pays no interest. Bitcoin faces a similar test.
• Next up: A hawkish Fed plus prolonged pipeline disruption would leave equities facing higher rates and weaker margins together — a considerably tougher setup than the usual debate over whether one technology stock had a good quarter.
