On February 28, 2026, the United States and Israel launched a coordinated military campaign against Iran — Operation Epic Fury — targeting nuclear facilities, military infrastructure, and regime leadership. Within 24 hours, oil markets woke up to a reality that economists had been modeling as a nightmare scenario for years: the Strait of Hormuz, the narrow channel through which one-fifth of the world's oil passes daily, was effectively shut down.
In less than two weeks, Brent crude surged from roughly $70 a barrel to a peak of nearly $120 — levels not seen since 2022. Prices have since pulled back to around $91-92 as of March 11, partly on Trump’s signals of a “short-term excursion” and the IEA’s announcement of a record 400 million barrel emergency reserve release, the largest in history. But the pullback does not mean the threat has passed. Gas prices are still up 20% nationally. Recession odds on prediction markets have doubled. The Dow swung 1,200 points in a single session. And the Federal Reserve, which had been inching toward interest rate cuts after two years of inflation-fighting, suddenly found itself cornered.
This is not a foreign policy story. This is a personal finance story. And if you haven't felt it yet, you will.
Here's what's actually happening — and what it means for your wallet, your portfolio, and your financial plan.
The Strait of Hormuz: The World's Most Expensive Chokepoint
To understand why this conflict hits Americans so directly, you need to understand one piece of geography: a 21-mile-wide shipping lane between Iran and Oman called the Strait of Hormuz.
Through that strait flows roughly 21 million barrels of oil per day — about 20% of global petroleum consumption and more than a quarter of all seaborne oil trade. Qatar, one of the world's largest exporters of liquefied natural gas (LNG), also ships the majority of its product through the same corridor. When the strait goes dark, the global energy market doesn't just slow down. It stops.
Since Operation Epic Fury began, that is effectively what has happened. Tanker traffic through the strait has been suspended. Iran retaliated with missile and drone strikes on US military bases in Qatar, Bahrain, and the UAE — the same Gulf states that host the infrastructure and refinery capacity the US and its allies depend on. By March 10, Kuwait, Iraq, Saudi Arabia, and the UAE had collectively lost a reported 6.7 million barrels per day of output due to damage, disruption, or operational shutdowns.¹
Qatar, which supplies roughly 40% of the world's helium — a critical input for semiconductor manufacturing — has halted gas production entirely after Iranian drones struck its export facilities. The ripple effects of that single disruption alone will be felt from Silicon Valley to Seoul.²
"For a long time, the nightmare scenario that deterred the US from considering an attack on Iran was that the Iranians would close the Strait of Hormuz," Maurice Obstfeld, former chief economist at the IMF, told Euronews. "Now we're in the nightmare scenario."³
Gas Prices: The Shock You're Already Feeling
Let's start with the most immediate hit: the pump.
Before the conflict began, the national average for a gallon of regular gasoline sat at roughly $2.98. As of March 11, 2026, that average has climbed to $3.58 per gallon — a roughly 20% increase in under two weeks, according to AAA data cited by CBS News and PBS NewsHour.⁴
California, as usual, is getting it worse. Drivers in the state are now paying $5.34 per gallon on average, up more than 12% from a week ago — partly because several California refineries have closed in recent years, leaving the state increasingly dependent on refined product imports from Asia, a supply chain that has been dramatically disrupted.⁵
But the gas price number you see at the pump is just the opening act.
Gasoline, diesel, and jet fuel are all derived from crude oil. When crude surges — as it did, spiking from roughly $67 to a peak of $120 per barrel — every fuel-derived product follows. Diesel powers the trucks that move your food. Jet fuel prices have doubled since the war began, and airlines are already implementing fuel surcharges that will reshape travel costs through summer.⁶
A one-way flight from Newark to Quebec City nearly tripled to $1,499. Flights from Los Angeles to Lima on LATAM Airlines rose from $499 to over $2,100, according to Center for American Progress analysis of Google Flights data.⁷
If you're planning summer travel, this is the signal to book or lock in now — not later.
Your Grocery Bill Is Next
The grocery aisle is the slow-moving target in this story. It hasn't been hit yet — but it will be.
"Food gets to the grocery store on diesel, whether it's on a truck or on a boat," said David Ortega, a professor of food economics and policy at Michigan State University, in an interview with PBS NewsHour. If oil prices stay elevated for a month or more, he added, "we're in different territory."⁸
Here's how the transmission works. Higher oil prices raise costs at every link of the food supply chain:
Fuel for farm equipment, processing plants, and refrigerated long-haul trucks all increase. Fertilizer — which is primarily derived from natural gas, much of it flowing through Hormuz — spikes in price. Nitrogen fertilizer costs are particularly sensitive to natural gas prices, and with Qatar's gas exports halted, that relationship is now under acute stress. The British Food Policy Institute has already warned of long-term increases in global food prices as a result of fertilizer market disruption.⁹
Up to 30% of the world's fertilizer exports — including urea, ammonia, phosphates, and sulfur — normally transit the Strait of Hormuz, according to the International Food Policy Research Institute. The blockade of the strait has already cut off fertilizer shipments, raising costs for farmers that will eventually pass to consumers.¹⁰
Early retail analyst projections estimate grocery prices could see increases of 2-4% if current fuel price trends persist through planting season. For a household already spending $800-$1,000 per month on food, that's another $16-$40 per month — not catastrophic in isolation, but compounding on top of everything else.¹¹
Imported goods — coffee, tropical produce, off-season fruits and vegetables — are especially exposed, given that global shipping is almost entirely reliant on fossil fuels. Domestic packaged goods will follow within 30-60 days, according to retail logistics analysts.¹²
The Inflation Trap: The Fed's Worst Nightmare
Here's where this gets genuinely complicated — and where the stakes for your financial life extend well beyond gas and groceries.
Going into March, the US economy was actually making progress on inflation. The Consumer Price Index rose 2.4% year-over-year in February — right in line with expectations, and down from its 3% peak in September 2025. Core inflation was sitting at 2.5%, and the Federal Reserve had started signaling openness to rate cuts by mid-2026.¹³
That window is now effectively closed.
JPMorgan economists estimate that the ~42% surge in US oil prices since the conflict began could push overall inflation from 2.4% to 3% or higher in the coming months. Gregory Daco, chief economist at EY-Parthenon, went further — projecting that the bump in gas prices alone could push monthly inflation as high as 1% in March, which would be the highest single-month increase in four years.¹⁴
"The path towards disinflation has become murkier," Deutsche Bank analysts wrote in a March 10 research note, warning that elevated energy prices could lead to higher headline inflation through spring.¹⁵
This matters because the Federal Reserve is now facing what economists call a stagflationary trap: rising inflation on one side, and a weakening labor market on the other. The March jobs report showed the US shed more jobs than it created last month, just as energy prices were surging. The combination of weak economic growth and hot inflation is the one scenario where the Fed has no clean policy tool — raising rates to fight inflation risks accelerating a recession; cutting rates to support growth risks letting inflation re-anchor higher.¹⁶
"The combination of a weak economy and high inflation is a worst-case scenario for investors because the Federal Reserve has no good tool to fix both problems at the same time," NPR noted in its March 9 market coverage.¹⁷
Former Fed Chair Janet Yellen has publicly warned that depending on the conflict's duration, economic growth will suffer and the Fed's ability to contain inflation will be severely constrained.¹⁸
Your Portfolio: What the Markets Are Telling You
Markets have been remarkably volatile — but they haven't broken. Understanding why requires a nuance most financial media is skipping over.
In the opening days of the conflict, the Dow fell over 1,200 points intraday before closing down just 400. The S&P 500 and Nasdaq actually turned positive by end of day, as investors digested the likelihood of a short conflict. By March 9, as oil briefly touched $120 and the jobs report came in weak, the Dow plunged a further 945 points intraday before closing down 453. Japan's Nikkei fell more than 5%. Europe's Stoxx 600 dropped nearly 5% over the same week.¹⁹
Recession odds on the prediction market Kalshi hit 33% on March 9 — up from 22% just one week earlier. Polymarket's recession probability briefly touched 43% before settling back to 30%.²⁰
Gold, the canonical fear trade, is testing record highs above $5,400 per ounce. The US dollar strengthened sharply, with the dollar index erasing all of its year-to-date losses in a single session. Morgan Stanley and other major banks are flagging defense, aerospace, domestic energy, and gold as the tactical overweights in this environment.²¹
For long-term investors, history offers some reassurance — but not a free pass. Strategists at Carson Group analyzed 40 major geopolitical events over 85 years and found that the S&P 500 loses an average of 0.9% in the first month after a crisis, then gains 3.4% over the following six months. After Russia invaded Ukraine in 2022, the S&P actually gained 3.27% in the first week — then fell 6% over the next year as inflation entrenched.²²
The key variable, as always: duration. A short conflict likely means temporary market disruption and recoverable oil prices. A prolonged one risks a structural shift in inflation, Fed policy, and global growth — with real estate, growth stocks, and consumer discretionary stocks as the biggest losers.
The Hidden Costs Most People Aren't Talking About
Beyond gas, groceries, and markets, there are several second-order effects that deserve attention:
Semiconductors and Tech Supply Chains
Qatar produces roughly 40% of the world's helium — a critical input for semiconductor chip fabrication. With Qatari gas facilities halted and helium exports effectively suspended, chipmakers from Intel to TSMC face upstream supply pressure. This is the kind of disruption that doesn't show up in next month's CPI — it shows up in device prices and chip lead times six to twelve months from now.²³
Mortgage Rates and the Housing Market
If the Fed holds rates steady — or is forced to raise them in response to resurgent inflation — mortgage rates will follow. The 10-year Treasury yield, which directly influences 30-year fixed mortgage rates, initially dipped to 3.96% at the conflict's start (a flight to safety), then reversed course and rose back above 4% as inflation fears overwhelmed the safe-haven bid.²⁴ Buyers hoping for relief in the housing market may be waiting longer than expected.
Defense Spending and the Federal Deficit
Operation Epic Fury is not cheap. US military operations using precision-guided munitions, stealth aircraft, and carrier groups run into the tens of billions of dollars per month of sustained operations. The EU defense commissioner has already flagged that US military costs have strained key missile stockpiles. The arms industry quadrupled weapons production three months ago in anticipation of sustained operations — costs that will ultimately register in the federal deficit and, over time, in interest rates on government debt.²⁵
Consumer Sentiment — Already at Record Lows
Consumer sentiment had already tumbled near record lows heading into this conflict, according to the University of Michigan's closely followed consumer surveys. Businesses are simultaneously facing higher transportation costs, elevated wages, and now energy shocks — while consumers are increasingly constrained by affordability. As Gregory Daco of EY-Parthenon put it: businesses are "really struggling in terms of your ability to find a relief valve on the pricing side."²⁶
What To Actually Do With This Information
A financial advisor's job in moments like this is not to forecast the end of the conflict. Nobody knows when this ends. Our job is to help you think clearly about what you can control — and what you can't.
At the pump and utility bill: Reduce discretionary driving where realistic. If you have variable-rate utility contracts, now is the time to inquire about locking in a fixed rate before natural gas prices transmit further downstream.
On groceries: Stock up modestly on non-perishables you already consume regularly. This is not panic-buying — it's sensible anticipatory purchasing at current prices before a likely 2-4% increase hits packaged goods shelves in the next 30-60 days.
On your portfolio: Do not panic-sell equities. History is clear on this. If you're feeling unusually anxious, that's a signal to review your risk tolerance — not a signal to act on it by selling. A small tactical shift from 80/20 equity/bond to 75/25 may be appropriate depending on your timeline, but wholesale moves to cash introduce inflation risk, opportunity cost, and tax events you may regret.
Sectors to watch: Domestic US energy producers (not dependent on Hormuz), defense and aerospace companies, gold and precious metals, and utilities are the conventional conflict-era hedges. They're already up. Talk to your advisor about whether increasing exposure makes sense for your situation.
On emergency cash: Financial advisors broadly recommend six to twelve months of expenses in cash or near-cash equivalents right now. High-yield savings accounts currently yield around 4.09%, and short-term T-bills are yielding roughly 3.6% while being exempt from state and local taxes. Both are reasonable options for your liquid reserves in a volatile rate environment.²⁷
On timing: If you were planning to refinance a mortgage, take out a home equity loan, or make a large credit purchase, those decisions deserve a second look in the current environment. Rates may not fall when you expected.
The Bottom Line
The US-Iran conflict is not a blip. Whether it ends in two weeks or drags on for months, the economic disruption it has already set in motion will take time to work through the system. Gas prices are up. Inflation expectations are rising. The Fed is cornered. Markets are volatile. And grocery and airline prices are following on a delayed fuse.
The American household enters this moment financially stretched — consumer sentiment already weak, affordability constraints already biting. Adding a global energy shock on top of that is not a minor inconvenience. It is a genuine financial planning event.
What gives some room for optimism: the US economy has absorbed geopolitical shocks before — Ukraine, COVID supply chains, tariff wars. It has shown genuine resilience. And if this conflict resolves within a few weeks without permanent infrastructure damage, many of the price spikes we're seeing will prove temporary.
But "hope it's short" is not a financial plan.
Know what you own. Know your timeline. And know that the best financial decisions in moments like this are almost always the ones you'd made calmly, before the crisis started — not the ones you make while checking oil prices at midnight.
