Jet Fuel Prices Near Wartime Highs, Stirring Cost Worries for Airlines and Travelers

Published Sep 18, 2026
Share:
Summary:
  • Gulf Coast jet fuel was $4.55 a gallon Thursday, with New York at $4.75.
  • Output slipped last week to the weakest level since early March, while inventories remain elevated but are moving back toward typical seasonal ranges.
  • A global fuel crunch centered on diesel is lifting jet prices too, since both are closely linked middle distillates.

Prices and production right now

Jet fuel costs have jumped back toward the peaks reached after the US and Israel began strikes on Iran in late February. On Thursday, the Gulf Coast benchmark printed $4.55 a gallon, a little more than 20 cents below those wartime highs, while New York was at $4.75. Refiners cut back, with last week's jet output the lowest since early March. Storage remains above average, but levels are sliding toward normal for this time of year, leaving room for further price firming.

Why supplies are strained

A broad fuel supply shock is rattling global energy markets, and diesel is bearing the brunt. Because diesel and jet are both middle distillates, their prices move together, and squeezing more diesel out of a refinery can mean less jet fuel, and vice versa.

Who felt the hit and how the summer unfolded

In the months right after the late-February strikes on Iran, jet fuel was viewed as the tightest refined product worldwide, as flows from the Middle East and Asia fell and limited storage for jet compounded the stress. Severe warnings surfaced in Europe about shortages, while New York, Los Angeles, and the Gulf Coast saw prices push to around or beyond $5 a gallon. The crunch lifted airfares and put airlines under heavy strain; it was cited as a proximate factor in Spirit Airlines' permanent shutdown in the US.

As summer progressed, US refiners pushed throughput to sustained highs, with jet fuel production exceeding 2 million barrels per day for 21 consecutive weeks - an intensity seen only rarely prior to the war. For long stretches, US tanks held far more jet than typical for the season, and exports surged.

When energy costs fluctuate, steady investment habits help protect your long term goals. Join Briefs Finance CEO Jaspreet Singh on September 29th for a FREE live investor workshop, How to Profit From A Dollar That's Losing its Value, where he shows how we're spotting investment opportunities as the dollar falls. Save your spot.

What this means for your portfolio

Jet and diesel tend to move together, and refiners juggle one at the expense of the other. With production dipping and inventories normalizing, fuel costs could stay jumpy, which can filter into airfare and travel budgets even if you are not flying often.

Keeping a calm, diversified approach lets you focus on growing and preserving wealth. Our CEO Jaspreet Singh is hosting a FREE live investor workshop, How to Profit From A Dollar That's Losing its Value, on September 29th. Sign up free to join him live.

Why America Bailed Out the Yen: The Japan Carry Trade, the Dollar and Your Mortgage Rate
  • In July 2026 the US sent money to steady the yen because Japan is the largest foreign owner of US debt, and Washington needs Japan to keep lending.
  • For decades the Japan carry trade let Wall Street borrow yen at essentially 0% and pour it into US stocks, real estate and Treasuries, and rising Japanese rates are shutting that off.
  • A weaker yen means fewer buyers for the dollar and for US debt, which pushes Treasury rates up and drags mortgage, car loan and credit card rates up with them.

Treasury Yields Are Spiking Because Lenders Are Backing Away From U.S. Debt
  • The U.S. is paying its highest 30-year borrowing rate in about two decades because its biggest lenders, the Fed, foreign governments, and banks, are all pulling back from Treasuries.
  • Every mortgage, car loan, credit card, and business loan is priced off the 10-year Treasury yield, so when Washington pays more to borrow, so do you.
  • With about $40 trillion of debt against a $32 trillion economy, the country either outgrows its debt or slides into a doom loop, and investors need a plan for both.

Fiat Currency Runs on Trust, and the World Just Stopped Trusting the Dollar
  • Gold has overtaken US treasuries as the world's top reserve asset, and central banks are now buying less US debt and more gold.
  • The US dollar is a fiat currency, meaning it's backed by a promise rather than gold, so it loses value when fewer countries want to hold it.
  • Whether the US economy or its national debt grows faster from here decides which assets stand to benefit next.

Why RAM Prices Are Soaring - and Where the Money Is Moving
  • Memory chips - the RAM inside phones, laptops, fridges, and trucks - are in a shortage Tim Cook called a 100-year flood, and some memory prices have climbed about 90% in a single quarter.
  • Four forces hit at once: AI demand, a production shutdown in 2023, build times that push any fix to 2028 at the earliest, and a bombed helium plant in Qatar.
  • The last two supply shocks ended in aggressive Fed rate hikes and market drops of around 45% and 20%, and this time Washington is spending heavily to bring memory production home.

How Is the Economy Doing? Washington Says It's Fixed, but the Numbers Don't Agree
  • Treasury Secretary Scott Bessent says the economy is fixed because lower earners' incomes are now rising faster than top earners'.
  • The Atlanta Fed and Bank of America show different numbers, and Hilton, Marriott, and McDonald's can't agree on what they're seeing either.
  • Whichever side is right, the economy is built to make investors rich, and inflation is how it does it.

US National Debt Hits $40 Trillion: Why the Economy Hasn't Collapsed Yet
  • The US national debt crossed $40 trillion in 2026 and is growing faster than the economy. The debt to GDP ratio now sits at 125%, the highest outside the pandemic and higher than World War II.
  • On September 9, 2026, Treasury Secretary Scott Bessent rolled out an emergency plan for the government to lend money to itself. Ray Dalio now says the dollar has roughly three years before real pain.
  • Empires rarely default. They debase. Since 1971, median household income grew about 8x while houses grew 17x and the S&P 500 grew 360x, so investors got richer while workers fell behind.

Your 401k Is Fueling the AI Bubble
  • About $10 trillion of 401k money sits in a $77 trillion stock market, mostly through target date funds and S&P 500 funds. Roughly 30% of every S&P 500 dollar lands in five AI-heavy tech stocks.
  • Four bubble signals run hotter today than before the 2000 crash: top-ten concentration, tech's share of the index, the Buffett Indicator, and how much of the market index funds own.
  • You only lock in an AI bubble loss if you sell. The 2022, 2020, 2008, and 2000 crashes were all buying windows for long-term investors, and the US-China AI race means government money could keep flowing in.

What Is Wealth Preservation? How To Protect Your Money From Anything
  • Wealth preservation is an investing strategy built around keeping the money you've already made instead of chasing growth.
  • It leans on assets that hold steady when markets fall - gold, Treasury bonds, and companies that keep earning through wars, crashes, and pandemics.
  • The tradeoff is real: you give up some upside, and the two key numbers to check are maximum drawdown and correlation to the market.

Why Is Everything So Expensive? Why Prices May Never Come Back Down
  • Official inflation is 3.4% and prices are up 32% since 2020, but rent (41%), gas (47%), car insurance (64%) and ground beef (79%) all outran the 28% median wage.
  • The Federal Reserve targets 2% inflation on purpose. Rising prices push extra dollars to investors and shrink the real cost of a $40 trillion national debt.
  • Investors who simply owned the S&P 500 gained about 150% over the same six years, and the Fed's September 16 decision will show whether it protects the dollar or the economy first.

The U.S. Housing Market Just Flipped: Renting a Home Now Beats Buying One
  • The US is in a buyer's market in 41 of the 50 largest metro areas, but prices sit near record highs and mortgage rates are close to 7%.
  • The same median house costs 27% more than it did in 2021 while the monthly payment costs 90% more, and incomes rose a little more than 10%.
  • A 2008-style crash is not showing up in the data, so the pressure is landing on buyers instead of prices.
