Oil at $89, Rate-Hike Bets Return: The August 12 Market Shocks Explained

The EIA raised its 2026 price forecasts. In its August Short-Term Energy Outlook released Tuesday, the EIA lifted its 2026 Brent crude forecast to $87 a barrel, up from $82 in its July forecast, and raised its U.S. retail gasoline estimate to $3.78 per gallon. The agency assumed Strait of Hormuz constraints would persist through August, with only about eight vessels crossing per day versus roughly 120 before the crisis . The EIA also estimated shut-in production at 5.5 million barrels per day for July .

Deutsche Bank warned of revived inflation fears. DB strategists noted that Brent had broken above $85 and closed near $88. They flagged higher 6-month futures and rising Euro inflation swaps as feeding renewed speculation of more hawkish central bank action .

Rates & Monetary Policy: A Hawkish Repricing

The 10-year Treasury yield surged 6.2 basis points. The benchmark U.S. 10-year yield climbed back above 4.70%, matching levels last seen in January 2025. Cleveland Fed President Beth Hammack's hawkish push on tighter policy contributed to the move .

September Fed rate hike odds returned above 50%. After July's weak jobs report had trimmed September hike probabilities toward 44%, the oil-driven inflation scare pushed pricing back above 50% . Three Fed officials dissented at the previous meeting in favor of an immediate hike, and markets had priced roughly a 63% chance of a September hike earlier in the month before the jobs data .

The one-year Euro inflation swap rose to 2.39%. Rising energy costs pushed eurozone inflation expectations higher, consistent with Deutsche Bank's observation that Euro inflation swaps were moving up in tandem with Brent's rally .

Equities & FX: Markets on Hold

U.S. equities were subdued ahead of Wednesday's CPI report. With Brent pushing toward $90, a hawkish Fed repricing under way, and the July CPI release due the next day, equity markets traded cautiously. The dollar traded sideways in Asian hours, shrugging off renewed Middle East attacks as FX markets waited for the inflation data .

A broader hawkish backdrop was in place. The Reserve Bank of Australia delivered a hawkish hold on policy rates on Tuesday, while traders increasingly bet the Bank of Japan could tighten again as soon as next month .

Geopolitics: Diplomacy at a Critical Point

Beyond the immediate market moves, the diplomatic landscape remained precarious. Qatar described the Iran-Oman talks on the strait's future as being at a "critical point." While this specific characterization was not independently verified in the available sources, the broader context — with U.S.-Iran deal hopes fading and fresh attacks on shipping vessels ongoing — matched the deteriorating outlook that markets were pricing . The Strait of Hormuz crisis, including ongoing Iran-Oman mediation efforts, remains the central driver of all the above market moves.

Bottom line: August 12 was dominated by a Strait-of-Hormuz-driven energy shock that ricocheted through rate markets, inflation expectations, and central bank policy bets, with everything left hanging on Wednesday's U.S. CPI print.
