Oil Prices Rise as Attacks Spark Strait of Hormuz Safety Fears

Oil prices rise this week as United States Oil Fund (AMEX:USO) shares climbed 4.38% to 108.92 dollars, a sharp bounce for a fund that has spent months sliding toward the bottom of its 52 week range of 102.42 to 154.08 dollars. The jump followed reports that tankers moving through the Strait of Hormuz had come under attack, reviving fears that a critical oil chokepoint could see disrupted shipping.

What Triggered the Jump in Crude

The United Kingdom's Maritime Trade Operations center said it had logged two separate attacks on vessels crossing the Strait of Hormuz. One ship was hit by an uncrewed aerial vehicle, the agency reported, while another sustained damage from an unidentified projectile. A third vessel off the coast of Oman caught fire after a separate strike. A United States official told NBC News that Iran's Islamic Revolutionary Guard Corps had fired missiles at two of the ships and struck a third with at least one drone, and that the American military intercepted additional drones launched by Iran.

Reuters also reported that one of the vessels, identified as the liquefied natural gas tanker Al Rekayyat, was at risk of exploding because of an engine room fire, though that account had not been independently verified. The Strait of Hormuz carries a large share of the world's seaborne oil, so any hint of military activity there tends to push traders toward pricing in supply risk immediately rather than waiting for confirmation.

Why Oil Prices Rise When Shipping Lanes Are Threatened

Crude markets react fast to Hormuz because there is no easy substitute route for the volume that passes through it daily. Even unconfirmed reports of drone or missile strikes are enough to add a risk premium to prices, since buyers cannot be sure whether tanker traffic will be delayed, rerouted, or insured at higher cost. That dynamic explains why USO jumped over 4% in a single session even though no formal blockade or extended outage has been declared.

Treasury Yields and Equities React

Government bond yields moved in tandem with oil, with the 20 year and 30 year Treasury yields (tracked by TLT on the downside as prices fell) breaking above 5%. The 10 year yield, which carries more weight for consumer borrowing costs, rose to its highest point since early June. Higher energy prices tend to feed inflation expectations, and bond investors demanded more yield to compensate.

Equities wobbled on the news before partially recovering. The S&P 500 (SPY) fell nearly 1% at the worst of the session before trimming losses to about 0.3% by early afternoon. The Nasdaq 100 (QQQ) took a harder hit, dropping as much as 2%, though that decline had more to do with a separate story unfolding in the chip sector than with oil itself.

Chip Stocks Add to Market Jitters

Samsung shares plunged 7% overnight after the company posted stronger than expected earnings that nonetheless fell short of the biggest bullish estimates. Deutsche Bank's Jim Reid noted the results beat forecasts by
