Crude oil is holding near its highest sustained level in years, with Brent settling at $100.53 a barrel and U.S. benchmark West Texas Intermediate at $89.79 on October 6, according to market data reported by Databoks. Brent had briefly traded above $102 a barrel days earlier, part of a roughly $100-to-$108 range that has held through early October as shipping through the Strait of Hormuz remains disrupted by months of tanker attacks tied to the broader U.S.-Iran confrontation.
The price run has been underway since mid-year and shows no sign of breaking. A year ago Brent traded in the mid-$60s; it is now up by roughly half, a move that has rippled well beyond energy trading desks and into the bond market, bank earnings and the Federal Reserve's own policy calculus heading into this week's run of corporate results.
A chokepoint under strain
Iran's Revolutionary Guard has repeatedly claimed to have closed the strait since the summer, while U.S. Central Command has just as often disputed that ships have stopped moving. What is not in dispute is that attacks on tankers and cargo vessels near the waterway have recurred for months, rattling insurers and shippers even when individual incidents cause limited damage. HSBC has gone as far as to call the strait "structurally impaired" in raising its own full-year Brent forecast, while analysts at DBS Bank have told clients they do not expect the standoff to resolve within three to six months.
Goldman Sachs has sketched out the downside: the bank says Brent could hold above $100 through the rest of 2026 if the closure drags on even one more month, a scenario that would keep pressure on fuel costs, shipping rates and headline inflation readings well into next year. Shippers have responded by rerouting some cargoes around the Cape of Good Hope and leaning more heavily on alternate Gulf export terminals, adding weeks to transit times and extra cost that eventually shows up in freight rates and, from there, in the price of imported goods.
Spilling into bonds and the Fed
The clearest sign the oil shock has become a macro story, not just an energy story, is in the bond market. The 10-year Treasury yield touched its highest level since 2002 earlier this month, briefly trading above 5.3%, while the 30-year yield has pushed toward 5.7% — moves that reflect both persistent inflation worries and a Federal Reserve that is no longer cutting. On September 16, the Fed raised its target range by a quarter point to 3.75%–4.00%, its first increase since 2023, citing elevated inflation and resilient growth even as it acknowledged uncertainty tied to geopolitical developments.
Inflation is too high and has been for too long.

That combination — a hawkish Fed and an energy shock that won't fade — is an unfamiliar one for markets that spent much of the past two years pricing in rate cuts. The relationship hasn't been purely calm: in early October, Dow futures fell nearly 500 points in a single session as oil jumped more than 5% following a fresh attack on shipping, a reminder of how quickly sentiment can turn when the Hormuz story flares. Even so, equities have mostly recovered on a weekly basis; the S&P 500 closed at a fresh high on October 9. But higher long-term yields raise funding costs across the economy, from mortgages to corporate borrowing, just as the biggest U.S. banks prepare to report third-quarter results this week.
Monday's session offered a preview of how thin conditions can get when the oil story resurfaces: with the bond market shut for Columbus Day and Japan and Canada also on holiday, traders flagged light liquidity and continued Iran-related risk as factors to watch into Tuesday's open. For now, the strait remains only partially open, the Fed has signaled it could hike again before year-end, and oil traders are left guessing how long a chokepoint crisis can keep reshaping both energy and interest-rate markets at once.
