President Donald Trump's immigration crackdown, combined with a wave of baby boomer retirements, is poised to upend longstanding assumptions about what constitutes a healthy labor market.

Immigration has been one of the most important engines of U.S. labor force growth in recent years, particularly as the native-born working-age population has plateaued. When fewer workers enter the labor pool through reduced immigration, the economy needs fewer net new jobs to keep the unemployment rate from rising.

For decades, Americans have been conditioned to expect that strong monthly payroll gains from the Labor Department would push unemployment lower, while weak or negative hiring would drive the jobless rate higher. Monthly job growth of roughly 125,000 to 150,000 was long viewed as the threshold needed to absorb new workforce entrants and keep unemployment stable.

However, with the labor pool now contracting, that calculus is shifting dramatically.

Breakeven Rate Turns Negative

A report from Dallas Fed economists earlier this year found that the breakeven rate of employment growth — the number of net new jobs required each month to hold the unemployment rate steady — actually turned slightly negative during the summer and fall of 2025. In other words, payrolls could stagnate or even shrink without pushing unemployment higher.

On Thursday, Oxford Economics estimated that the breakeven rate currently sits at approximately 50,000 new jobs per month, a sharp decline from more than 200,000 during 2022 and 2023, when immigration was surging.

Economists Matthew Martin and Bernard Yaros project the breakeven rate will fall to zero next year and turn slightly negative by 2028. Their forecast assumes that Trump's restrictive immigration policies remain in effect throughout the remainder of his term and that the baby boomer retirement "tsunami" — expected to peak between 2026 and 2029 — continues to compress the labor force. With roughly 10,000 Americans reaching retirement age each day, the demographic wave is accelerating the supply-side shift already underway.

"Today, the labor market's speed limit is much lower than just a few years ago, setting the stage for a jobless expansion," Martin and Yaros wrote in a note.

No Layoff Wave Expected

A negative breakeven rate does not necessarily mean widespread layoffs are imminent. Oxford Economics anticipates job growth will remain slightly positive, supported by sectors such as healthcare that are relatively insulated from the business cycle. Martin and Yaros predicted "gentle downward pressure" on unemployment over the next couple of years.

The implication for monetary policy is significant. The Federal Reserve operates under a congressional dual mandate to pursue both stable prices and maximum employment, meaning it scrutinizes jobless data closely when setting interest rates. Even anemic payroll reports are unlikely to trigger a Fed response, provided the jobless rate remains essentially unchanged.

"Slowing or falling employment would have to be accompanied by a large move higher in unemployment and other signs of weakness for the Fed to step back from considering rate hikes and pivot back to cuts," they added.

Labor Hoarding and Tight Supply

The shrinking labor supply has fostered a low-hire, low-fire environment, although recent months have shown a pickup in job growth. Despite Trump's tariffs, the conflict with Iran, and related price spikes, initial jobless claims have remained low.

Employers may be reluctant to shed workers partly out of concern that the labor market will tighten further, BNP Paribas economists Britney Jackson and James Egelhof said in a Friday report. They pointed to the Supreme Court's ruling allowing the White House to end temporary protected status for certain noncitizen workers, a decision that could reduce the documented labor force by several hundred thousand people. Temporary Protected Status, or TPS, grants work authorization to individuals from countries designated as experiencing conditions such as armed conflict or natural disaster.

"This could translate into further downside pressure on the unemployment rate, due to both a declining documented workforce and possibly increased 'labor hoarding' by firms, a phenomenon last observed during the pandemic," Jackson and Egelhof wrote.
