Oil Tops $100 as Fed Hike Odds Surge Past 90 Percent

Crude oil prices extended gains above $100 per barrel on Tuesday, driving broad declines across Asian equity markets. Investors are pricing in a high probability of a Federal Reserve interest rate increase this week, fueled by persistent inflation risks from the energy sector.

Crude oil contracts climbed more than 1 percent on Tuesday. This move pushed prices above the $100 per barrel mark. The increase followed a sharp spike earlier this month driven by geopolitical instability. Houthi rebels in Yemen have seized control of the Bab al-Mandab Strait. This blockade has become critical as the Strait of Hormuz faces restrictions due to US-Iran tensions. Saudi Arabia also closed its East-West pipeline after drone attacks. These supply disruptions have directly increased global inflation pressures.

Market participants are reacting to rising energy costs by adjusting expectations for monetary policy. US diesel prices topped $6 per gallon on Friday. The 10-year US Treasury yield sat just below 5 percent. This level marks the highest point since October 2023. Traders are now assigning a greater than 90 percent probability to a Federal Reserve rate hike. The European Central Bank already raised rates last week. The focus has shifted entirely to the upcoming Fed decision this week.

Asian equities fall on rate fears

Most major Asian stock indices declined on Tuesday. Investors pulled back from risk assets ahead of the US monetary policy decision. Hong Kong, Shanghai, Sydney, Singapore, Wellington, and Taipei all recorded losses. Only Tokyo, Seoul, and Manila finished higher. The broad retreat reflects cautious positioning as traders weigh the impact of higher borrowing costs on regional growth.

Tech sector shows limited recovery

Technology stocks provided modest support to the Japanese and Korean markets. Shares in Samsung and SK hynix edged upward in Seoul. Kioxia and SoftBank posted gains in Tokyo. However, these firms did not fully recover from Monday’s losses. The recent volatility stems from concerns over the pace of AI development. Industry leaders, including Anthropic CEO Dario Amodei, have called for a coordinated slowdown. This debate has forced traders to reassess valuations that rose sharply in August after July’s selloff.

Geopolitical risks drive inflation outlook

The conflict in the Middle East remains the primary driver of market stress. Yemen’s Houthi rebels are fighting the Saudi-backed government. Their control of the Red Sea coast disrupts vital shipping routes. US President Donald Trump stated that Iran wants a deal quickly. He noted that the US is open to engaging in talks. Despite these diplomatic signals, the physical supply constraints have already locked in higher energy costs. Analysts cited by GN markets/policy (en-US) indicate that these costs are forcing central banks to act decisively against inflation. The combination of supply shocks and policy tightening creates a challenging environment for global equities.
