Oil Hits $100: Three Market Signals Investors Should Watch

Brent crude oil prices topped $100 per barrel on Thursday morning, extending gains for a fifth consecutive session as escalating tensions in the Middle East fueled fears of supply disruptions.

The move has already triggered noticeable reactions across financial markets, from energy stocks to Treasury yields and foreign exchange, suggesting investors are beginning to position for a potentially more inflationary backdrop.

Why Oil Is Rising Oil prices – as closely tracked by the United States Oil Fund (NYSE: USO ) – accelerated after geopolitical risks intensified in the Middle East.

The latest catalyst came after Iran-backed Houthi militants attacked two Saudi oil tankers in the Red Sea, marking the first direct strikes against tankers in the strategic waterway.

The attacks added to concerns over potential disruptions to a critical export route for Saudi crude.

The escalation follows the collapse of diplomatic efforts between the United States and Iran and comes as military activity in the region continues to intensify, raising fears that oil supply risks could spread beyond the Strait of Hormuz.

While crude itself is back in focus, the more interesting story may be how other markets are already responding.

1.

Energy Stocks Are Leaving The Broader Market Behind The first signal is coming from equities.

The Energy Select Sector SPDR Fund (NYSE: XLE ) has gained over 12% month-to-date, dramatically outperforming the SPDR S&P 500 ETF Trust (NYSE: SPY ), which has been essentially flat over the same period.

The divergence suggests investors are rotating toward companies that stand to benefit from higher crude prices, including integrated oil producers and refiners, as expectations for stronger earnings improve.

Since the start of the month, shares of Marathon Petroleum Corp. (NYSE: MPC ) have rallied by 23%.

Peers Phillips 66 (NYSE: PSX ) and HF Sinclair Corp. (NYSE: DINO ) soared by 25% and 30%, respectively.

Bond Markets Are Pricing A More Hawkish Fed The second signal comes from the Treasury market.

The yield on the 2-year U.S.

Treasury note climbed to approximately 4.35%, its highest level since February 2025.

Unlike longer-dated bonds, the two-year Treasury is highly sensitive to expectations for Federal Reserve policy.

Higher energy prices risk feeding through into headline inflation, potentially complicating the Fed’s path toward easier monetary policy.

Fed funds futures now imply roughly two additional rate hikes over the next 12 months.

According to the CME FedWatch Tool, which converts futures prices into implied probabilities for each Fed meeting, traders now assign a 35.8% chance of a rate hike at the July 29 meeting, from the current 3.50%–3.75% target range.

By the January 2027 meeting the market puts a 96.8% probability on rates sitting at 4.00%–4.25%.

3.

The Dollar Is Hammering Low-Yielding Currencies Like Yen The third major signal is emerging in foreign exchange markets.

The U.S. dollar climbed above 163 Japanese yen, reaching its strongest level since 1986.

The move reflects widening interest-rate differentials as investors anticipate U.S. rates remaining higher for longer.

Japan faces an additional headwind.

As one of the world’s largest net importers of crude oil, higher energy prices worsen the country’s import bill, adding further pressure on the yen alongside the Bank of Japan’s accomodative monetary policy.
