National Gas Prices Rise One Dollar Per Gallon in 30 Days Amid Strait of Hormuz Disruption

The national average price for a gallon of regular gasoline rose from approximately $2.98 to $3.98 over 30 days, a one-dollar increase driven by the U.S.-Iran conflict and disruption to shipping through the Strait of Hormuz.

The Strait of Hormuz handles roughly 20% of global oil shipments. Brent crude rose 36% from late February through March 27, trading above $113 a barrel, up from approximately $70 before the conflict.

Consumer and Economic Indicators

The University of Michigan consumer sentiment index dropped to 53.3 in the final March reading, down from 56.6 in February. The short-term economic outlook fell 14%. Expectations for personal finances over the next year declined 10%. Year-ahead inflation expectations rose to 3.8%, the largest monthly increase since April 2025.

The OECD revised its U.S. inflation forecast from 2.8% to 4.2% for 2026.

Bank of America data shows gasoline spending was up more than 14% year over year in the second week of March. The average American household is projected to spend an additional $740 on gas in 2026 due to the price increase.

Recession Probability Estimates

Goldman Sachs raised its recession probability estimate to 30%, up five percentage points, and cut its GDP growth estimate to 2.1%. The firm projects growth cooling to 1.25% to 1.75% in the second half of 2026.

J.P. Morgan estimates U.S. recession odds at 35%. Moody's Analytics places them at 49%. Wilmington Trust is at 45%. EY Parthenon estimates 40%.

Mark Zandi of Moody's Analytics stated his estimate could cross 50% if oil prices remain elevated.

Federal Reserve Position

The Fed held its benchmark rate at 3.5% to 3.75% at the March meeting. Cutting rates could accelerate inflation, while raising rates could further slow an already weakening economy.

Geopolitical Factor

The price increase stems from a geopolitical event rather than a monetary policy issue. The Fed and Congress have limited tools to address a supply disruption at a physical chokepoint in the global oil supply chain. Resolution depends on military and diplomatic developments.

CNN reported that consumer confidence has declined even among higher-income Americans, a group that was largely insulated from the 2022 inflation period.

The Dow Jones Industrial Average dropped 768 points in a single session after the Fed signaled it would not cut rates in the near term.

Price Outlook

Even if oil prices returned to $70 immediately, gasoline prices would take weeks to decline. Consumer sentiment recovery typically lags price changes. Businesses that have raised prices in response to higher input costs historically do not reduce them quickly.

If oil remains above $100 and inflation reaccelerates past 4%, the Fed faces a decision between addressing inflation and supporting economic growth.

So this is just a bunch of numbers to me. All I know is when I am driving Uber, I feel it. It’s not like Uber is going to start giving me a better split out of the goodness of their hearts. My bill at the pump went up from 35 bucks every two days to $45. Over a month that is an extra $150. I am a Veteran. I don’t like the thought of American soldiers with boots on ground for dumb reasons. But this one is tough, I am of the opinion that Iran absolutely cannot be allowed to have nuclear weapons. Their willingness to openly attack other countries who have supported the United States is irrefutable proof of this.
