Your Borrowers Just Got a Pay Cut. They Don’t Know It Yet.

For nearly three years, American workers had been winning a quiet battle against inflation. Since March 2023, when post-pandemic price pressures finally began cooling, wage gains had been outpacing price increases by roughly one percentage point. Workers were earning more in real terms. Disposable income was slowly rebuilding. Consumer credit was holding up.

The Iran war ended that in a single month.

When adjusted for inflation, average hourly earnings grew at an annual rate of just 0.3% in March — down from 1.3% in February. Nominal wages are rising at 3.5% annually. Inflation just printed at 3.3%. The gap between them has collapsed to near zero. For the median American worker, the Iran war energy shock has effectively eliminated three years of real income gains in about six weeks.

The math that will drive your Q3 delinquencies

Non-supervisory workers — roughly four in every five non-farm employees — are seeing wage gains of 3.4% annually, the slowest pace since 2021. Gasoline alone is up 21% in March. The national average at the pump is now $4.09, up more than $1 per gallon from a month ago. Diesel has broken $5.50 per gallon, compared to $3.89 a month ago.

For a borrower commuting 15,000 miles per year in a vehicle averaging 25 miles per gallon, the March gas price increase alone adds approximately $600 annually in fuel costs — roughly $50 per month. That is $50 per month that was not in their budget when they applied for their loan, took on a new credit card balance, or enrolled in an installment plan. It is $50 per month that now competes directly with their minimum payment.

This is before the secondary price increases hit. Amazon has already announced a 3.5% fuel and logistics surcharge on sellers beginning April 17. Airlines are raising bag fees. The International Air Transport Association reports jet fuel is up 104% over the past month. Transportation costs flow into virtually everything a consumer buys — groceries, retail, delivery services, healthcare supply chains. The full inflationary impact of the March energy shock will not be visible in consumer budgets until May and June, and it will not show up in loan delinquency data until July and August.

The labor market freeze compounds the problem

Workers cannot solve a real wage squeeze by switching to higher-paying jobs — because the labor market has effectively frozen. Stanford economist Nicholas Bloom described it precisely: the job market is in a “low-hire, low-fire” state that the Iran war is likely to freeze further. Employers are hiring at their lowest rates since 2013, outside of the pandemic onset. Workers are clinging to their jobs rather than quitting for better pay, because quit rates are at their lowest sustained level in a decade.

This matters for consumer lenders in a specific way. In prior periods when inflation squeezed household budgets — 2021, 2022 — workers had a release valve: they could change jobs for a pay raise. Quit rates were at record highs, wage competition was fierce, and workers regularly captured 10–15% pay bumps by switching employers. That release valve is gone. A borrower whose real wages just went negative cannot solve the problem by job-hopping. They are, as Bloom put it, “trapped.” Their only adjustments are to cut spending, draw down savings, or fall behind on debt service.

Goldman Sachs estimates the Iran war is already costing the US labor market 10,000 jobs per month, with leisure, hospitality, and retail absorbing the sharpest losses. These are the same sectors whose workers spend the highest share of income on gasoline and carry the least savings buffer. The hit is concentrated exactly where financial resilience is lowest.

Who is most exposed in your portfolio

Near-prime and subprime borrowers with service sector jobs. Healthcare aides, restaurant workers, retail employees, delivery drivers — these borrowers commute more, spend more of their income on fuel, and have the least discretionary income to absorb a shock. They are also the borrowers who cannot refinance their way out of stress, cannot cut housing costs, and cannot defer essential spending. This is the segment where delinquency pressure builds first and fastest.

Borrowers with high debt-service ratios. A borrower who applied with a 45% debt-to-income ratio in 2025, when real wages were growing, is now effectively at a higher effective DTI in 2026 — because their real disposable income has fallen while their fixed obligations have not. Point-in-time underwriting metrics from origination do not capture this deterioration. Income-adjusted stress testing does.

Gen Z borrowers specifically. Bank of America Institute data shows Gen Z carries the highest ratio of gasoline spending to discretionary spending of any generation. After nearly two years of finally catching a financial break — with rent growth slowing and wages rising around 9% year-over-year — BofA economists warned in late March that this recovery “could be snuffed out before it fully takes hold.” The March data confirms that concern. Gen Z’s real wage position deteriorated sharply in a single month.

The timeline consumer lenders need to internalize

Navy Federal Credit Union chief economist Heather Long put the forward guidance plainly: “It’s going to get a lot worse before there’s any relief. Even if the war on Iran ends in two weeks, and there’s magically an agreement, inflation will continue to rise for months to come.”

The transmission lag is 60 to 90 days from price shock to loan performance. March’s energy spike will show up in April and May budgets. Missed payments from April and May budgets will appear in June and July loan performance data. If you are adjusting underwriting or loss reserve assumptions in response to Q2 delinquency readings, you are already three months behind the signal. The signal is available today: real wages just went to near-zero growth while inflation ran at 3.3%. That is the underwriting environment for every loan originated in Q2 2026.
