Oil jumps, Fed hawkish, Jobs data - What’s moving markets
August 31, 2026
Oil prices surged while U.S. stock futures slipped on Monday as renewed U.S.-Iran military tensions in the Strait of Hormuz collided with a more hawkish Federal Reserve outlook and a crucial week of U.S. economic data.
Markets are facing several major catalysts at once, including rising crude oil prices, renewed geopolitical risks, changing Federal Reserve interest-rate expectations and upcoming U.S. employment figures.
The combination has increased uncertainty across global financial markets as investors assess the outlook for inflation, interest rates, stocks, bonds and energy prices.
Oil Prices Rise as Strait of Hormuz Risk Returns
Crude oil prices moved sharply higher after the United States launched fresh strikes against Iran and Iran responded with attacks on two U.S. bases in Jordan.
Brent crude oil climbed strongly toward the $90-per-barrel area, while WTI crude oil also advanced. The renewed conflict has raised concerns about potential disruptions to global energy supplies because the latest strikes occurred on Larak Island near the strategically important Strait of Hormuz.
The Strait of Hormuz is one of the world's most important oil-shipping routes. Any disruption to transportation through the waterway could create significant volatility in global crude oil markets.
Higher oil prices are particularly important for investors because rising energy costs can increase transportation and production expenses. If the increase in oil prices persists, it could also add to inflationary pressures and complicate the Federal Reserve's interest-rate decisions.
U.S. Stock Futures Slip as Geopolitical Risks Increase
U.S. stock futures edged lower at the start of Monday's trading session as investors reacted to renewed U.S.-Iran fighting.
S&P 500 futures and Dow futures moved lower, while Nasdaq 100 futures were broadly stable.
The renewed military escalation adds another layer of uncertainty for Wall Street. Investors are closely watching whether higher oil prices and geopolitical tensions could affect corporate earnings, consumer spending and inflation expectations.
Technology and growth stocks could remain particularly sensitive to changes in interest-rate expectations because higher borrowing costs can reduce the attractiveness of high-valuation assets.
Fed Hawkishness Boosts September Rate-Hike Bets
Another major market driver is the Federal Reserve's increasingly hawkish policy outlook following Fed Chair Kevin Warsh's remarks at the Jackson Hole symposium.
Federal funds futures are now indicating roughly a 60% probability of a 25-basis-point interest-rate increase at the September 16 meeting, compared with around 35% before Warsh's speech.
Warsh emphasized that the Federal Reserve still has substantial work to do to bring inflation under control. His comments have strengthened expectations that U.S. interest rates could remain elevated for longer or potentially rise if inflation continues to prove persistent.
A higher-rate environment could support Treasury yields and the U.S. dollar while creating additional pressure on equities, particularly technology and other growth-oriented stocks.
U.S. Jobs Data Becomes the Next Major Market Catalyst
Investors now turn their attention to a busy U.S. economic calendar that could determine the Federal Reserve's next policy move.
Key economic releases scheduled for the week include:
JOLTS job openings report
ADP private payrolls
ISM manufacturing data
U.S. nonfarm payrolls
Additional comments from Federal Reserve officials
Friday's U.S. nonfarm payrolls report will be especially important because it could provide fresh evidence about the strength of the American labor market.
A stronger-than-expected jobs report could reinforce expectations for tighter monetary policy and potentially increase September rate-hike bets. Conversely, weaker employment data could encourage the Fed to adopt a more cautious approach.
Iran Sanctions Add Pressure to Global Markets
The United States is also increasing financial pressure on Iran through additional sanctions.
U.S. Treasury Secretary Scott Bessent has warned that Washington could announce new secondary sanctions on a regular basis, initially focusing on banks and financial institutions linked to Iran.
The latest measures add another source of uncertainty for investors and could affect energy markets, regional trade and financial flows.
Washington has also imposed sanctions on UAE branches of Egypt's Banque Misr over alleged financial connections to Iran.
What Markets Are Watching Now
The market outlook is increasingly being shaped by three major themes: oil prices, Federal Reserve policy and U.S. economic data.
If geopolitical tensions intensify and crude oil prices continue climbing, inflation expectations could rise. At the same time, stronger U.S. employment data could give the Federal Reserve more justification to maintain a restrictive monetary policy.
For Wall Street, the key question is whether economic data will support the Fed's hawkish stance or provide evidence that the U.S. economy is losing momentum.
Market Outlook
Investors should closely monitor Brent crude oil, WTI crude oil, the U.S. dollar, Treasury yields, S&P 500 futures, Nasdaq futures, gold prices and Federal Reserve rate expectations as the week develops.
The combination of U.S.-Iran tensions, Strait of Hormuz risks, higher oil prices, Fed interest-rate uncertainty and U.S. jobs data could create significant volatility across financial markets.
