How the July 2026 Strait of Hormuz Crisis Drove Oil to Six-Week Highs and Reshaped Markets

Inflation fears reignited

The oil spike directly revived inflation anxieties that had briefly eased during a truce window. BlackRock estimated the conflict would add roughly 0.8 percentage points to global headline inflation . Goldman Sachs warned in a mid-July note that Brent staying near $78/bbl — well above its pre-war level of ~$70 — had a "knock-on effect for inflation expectations," feeding into broader price pressures beyond just energy . By late July, the New York Times reported that a potential Houthi blockade in the Red Sea was "heightening apprehensions" about energy supply chains, keeping inflation fears elevated .

Fed rate hike expectations strengthened significantly

Higher oil and inflation directly repriced interest rate probabilities.

• Early July: The renewed strikes initially boosted bets on a hawkish Fed. On July 9, CNBC reported that the oil spike "boosted expectations the Federal Reserve could soon raise interest rates" . Minutes from the Fed's June meeting had already shown policymakers concerned about war-driven inflation .
• Mid-July crosscurrent: Softer-than-expected June CPI data on July 14 temporarily reduced the odds of a July hike to just ~10% . However, the oil-driven inflation narrative persisted.
• Late July surge: By July 22–23, as Brent pushed toward $100, CME FedWatch data showed the probability of a rate hike at the September 2026 meeting had surged to 82% . Money markets were also pricing in a meaningful chance that the Fed would need to raise rates again later in the year if oil kept inflation under pressure .

Currency markets — dollar strengthened then pivoted

The dollar initially rallied on the geopolitical shock. On July 8–9, the greenback stood tall as Gulf tensions fueled oil gains and Fed hike bets, with the dollar index backing off multi-week highs but remaining supported . However, by July 14–16, softer U.S. inflation data (core CPI cooling more than expected) overrode the geopolitical bid, pushing the dollar to a one-month low as markets priced out a July rate hike . The net effect was a tug-of-war: war-driven inflation and rate-hike expectations supported the dollar, but cooling domestic inflation data limited its upside.

Gold prices fell — a safe-haven "paradox"

Gold, normally a geopolitical safe haven, sold off sharply. This counterintuitive move occurred because the oil spike raised inflation and Fed rate hike expectations, which increased the opportunity cost of holding non-yielding bullion.

• July 8: Spot gold fell 0.1% to $4,100/oz as U.S. strikes boosted the dollar and rate-hike bets .
• July 13: Gold dropped ~1.5% to $4,060/oz as Strait of Hormuz closure fears sent oil surging .
• July 14: Gold fell another 2.6% to ~$4,017/oz, its lowest since July 1, as analysts noted the "safe-haven paradox" — geopolitical tension was bearish for gold because it raised inflation and Fed rate expectations .
• July 16–17: Gold headed for a weekly fall as Hormuz strikes kept feeding Fed hike bets .

Key takeaway: The July 2026 escalation created a clear transmission chain — Hormuz disruption → oil at six-week highs → higher inflation expectations → stronger Fed rate-hike odds (82% by late July) → dollar supported initially → gold sold off as rate expectations outweighed safe-haven demand.
