# Oil's 5% Jump Lifts the Ten-Year Treasury Yield to 4.70% Before Wednesday's US Inflation Report

With the Strait of Hormuz still closed, the market-implied probability of a Federal Reserve rate increase has returned to about 50%, and bitcoin failed to hold $65,000 for a fourth straight day.

Crude oil rose about 5% on Monday after Iran and the United States hardened their positions on reopening the Strait of Hormuz, and the increase quickly pushed up US Treasury yields. Brent crude traded [above $86 a barrel](https://www.aljazeera.com/economy/2026/8/10/oil-prices-climb-as-iranian-demands-cloud-outlook-for-strait-of-hormuz), a fourth consecutive session of gains, while US crude rose 4.9% to about $82. The ten-year Treasury yield [climbed to 4.70%](https://www.thestreet.com/stock-market-today/stock-market-today-dow-jones-sp-500-nasdaq-updates-aug-10-2026), and the three main US equity indices closed slightly lower, with the S&P 500 at 7,751.86 and the Dow Jones Industrial Average at 53,869.37.

The Israeli financial daily Globes reported in its Tuesday morning market update that the [probability of a US interest-rate increase had moved back to 50%](https://www.globes.co.il/news/article.aspx?did=1001551846#utm_source=RSS), that oil prices were steady in Asian trading after the previous day's jump, and that gains in Samsung Electronics shares pushed the Seoul market up by more than 1% while Tokyo was closed for a public holiday.

The trigger was diplomatic. Iran's negotiators asked Washington for compensation for damage from five months of fighting and demanded that the United States lift its naval blockade before the waterway reopens. President Donald Trump [responded by demanding payment from Iran](https://www.thehindu.com/news/international/iran-us-war-live-updates-august-11-2026-hormuz-strait-reopen-us-iran-talks/article71330825.ece) for what he described as 50 years of damages, and said the US Navy has cleared the strait of mines and now controls it fully. Neither side has produced a written agreement.

Wednesday's July Consumer Price Index (CPI) report matters more than usual because of this. An energy shock raises measured prices without any change in the money supply, and an analysis grounded in Austrian economics, which separates supply-driven price effects from monetary causes, keeps the two apart: the strait is a supply constraint, while the question of whether US monetary policy is still too loose rests on the credit expansion of prior years, not on this month's oil price. The Federal Reserve has no tool that reopens a waterway. It has a tool that suppresses demand for everything else, by raising interest rates. Gold and silver reflected the same tension between a supply shock and a policy response. Gold [traded near $4,375 an ounce](https://finance.yahoo.com/personal-finance/investing/article/gold-prices-today-monday-august-10-2026-highest-opening-price-since-early-june-123242269.html) on Monday, with silver in the mid-$60s, while bitcoin [failed to hold $65,000 for a fourth day](https://www.coindesk.com/markets/2026/08/11/xrp-ether-lead-crypto-losses-as-traders-eye-usd70-000-bitcoin-next) as the oil rally renewed inflation concerns.

## What this means

A closed strait raises headline inflation through higher fuel and freight costs, and the Federal Reserve can only respond by raising short-term interest rates (the front end of the yield curve). Borrowers exposed to those rates, emerging-market governments that borrow in dollars, and growth stocks whose value rests on future earnings (long-duration equities) all lose ground if the July inflation report pushes up the odds of a September rate increase. Energy producers and holders of physical gold and silver gain from the same dynamic, because a supply-driven price increase combined with tighter policy reduces the value of assets priced on future cash flows while leaving scarce physical assets unaffected.

## What to watch

- Wednesday's July US consumer price report and Thursday's producer price report: if the effect of higher energy costs shows up in core services rather than just fuel, the case for a September rate increase strengthens considerably.
- Whether Iran and Oman convert their draft agreement into a signed reopening arrangement, since any credible schedule for tanker traffic would remove much of the premium currently built into Brent crude prices.
- The ten-year Treasury yield relative to the price of gold: both rising together would indicate that investors are pricing in inflation risk rather than economic growth, a different market dynamic than a simple reaction to expected rate increases.
