Home Equity Lines of Credit Are Becoming a Hidden Time Bomb as Property Values Fall

Published: March 15, 2026 | By Mariusz Kurylo

American homeowners collectively withdrew an estimated $390 billion from home equity lines of credit (HELOCs) during the 2020–2023 period, extracting value from the dramatic appreciation of their homes to fund home improvements, debt consolidation, education costs, and consumption. The Federal Reserve's consumer finance data, compiled by Bloomberg, showed that outstanding HELOC balances reached their highest level since 2010 by the end of 2025, as both new originations and existing lines being fully drawn contributed to growth in this category of consumer debt.

What had seemed like prudent use of home equity in 2021 — when home values were rising, rates were low, and the equity cushion was expanding faster than any borrowing against it — was beginning to look more fraught in early 2026. Home prices in the markets where HELOC usage had been most intensive (coastal California, metro New York, Sun Belt boomtowns) were declining. The HELOC rate itself, tied to the prime rate (which moves directly with the Federal Reserve's policy rate), was sitting at approximately 9.25% — making HELOC debt among the most expensive forms of secured borrowing available to homeowners. And the repayment dynamics of HELOC structure created a payment cliff that many borrowers were approaching without adequate financial preparation.

Federal Reserve data and the Office of the Comptroller of the Currency both flagged rising HELOC delinquency rates in their regular banking system reports, with the 30-day delinquency rate for HELOCs reaching approximately 2.8% nationally by late 2025 — up from approximately 1.1% in 2021, according to Bloomberg's compilation of regulatory data. While 2.8% might appear modest in absolute terms, the direction of change and its coincidence with falling home values was the key concern for bank risk managers and housing economists.

How HELOCs Work — and Where the Risk Lives

A home equity line of credit is a revolving credit facility secured by the borrower's home equity — the difference between the home's value and the outstanding first mortgage balance. During the "draw period" (typically 10 years), the borrower can access the line up to its credit limit, paying interest only on the drawn amount. At the end of the draw period comes the "repayment period" (typically 10–20 years), during which the borrower must pay down the outstanding balance through both principal and interest payments.

The draw period to repayment period transition is the payment cliff: a borrower who spent 10 years paying interest only on a $150,000 drawn balance at a variable rate suddenly faces amortized principal-plus-interest payments that can be two to three times the prior interest-only cost. Wall Street Journal analysis of HELOC origination data showed that a large cohort of HELOCs originated in 2013–2015 — when the prior housing recovery generated new equity and low rates made HELOCs attractive — were entering their repayment periods in 2023–2025, creating a payment shock wave on top of the already-stressed affordability environment.

For the post-2020 cohort of HELOCs, the draw period wouldn't end until 2030–2033 in most cases, so the repayment cliff risk was more distant. But the current risk was more immediate: rising rates had already increased the interest cost on drawn HELOC balances substantially (from prime-minus-something when rates were low, to prime-plus-a-spread in the current environment), and declining home values were threatening the equity cushion that secured the lender and gave the borrower refinancing options.

The "Frozen Equity" Problem

A critical mechanism connecting falling home prices to HELOC stress was what housing finance researchers called the "frozen equity" problem. When a home's value declines to the point where the combined balance of the first mortgage and the HELOC approaches or exceeds the property's market value, the homeowner faces several disabling constraints: they cannot refinance the first mortgage without also retiring or subordinating the HELOC; they cannot sell the home without bringing cash to closing; and lenders have the contractual right to freeze or reduce the HELOC if the property's value falls below specified thresholds.

Bloomberg reported multiple cases of banks exercising their right to freeze HELOC lines — notifying borrowers that they could not draw further on the line because a new automated property value estimate suggested the collateral coverage had deteriorated. For homeowners who relied on the HELOC as an emergency liquidity reserve or were actively drawing to fund ongoing home renovation projects, a sudden freeze was a significant financial disruption.

Reuters documented class action lawsuits filed against several banks that had frozen HELOC lines in the 2022–2023 rate rise period, with borrowers arguing that the automated value estimates used to justify freezes were inaccurate or applied without adequate notice. Banks generally prevailed in these disputes given the clear contractual language authorizing freezes, but the litigation highlighted the human cost of the HELOC freeze mechanism.

The most vulnerable borrowers were those who had drawn their HELOC to maximum capacity — essentially having consumed their home equity in liquid form — and were now facing both the interest burden of the full drawn balance at elevated rates and the diminished collateral supporting the line. For these borrowers, a loss of income or an unexpected major expense could create a cascade: inability to service the HELOC leading to default, lender foreclosure on the HELOC (which as a second lien required paying off the first mortgage balance first from any proceeds), and ultimate loss of the property.

Which Banks Have the Most HELOC Exposure

HELOC lending is concentrated among large retail banks with substantial consumer banking franchises. Wells Fargo, Bank of America, and JPMorgan Chase collectively hold the largest HELOC portfolios nationally, with aggregate balances in the tens of billions at each institution, according to FDIC Call Report data analyzed by Bloomberg. Regional banks with heavy retail banking presences in markets with high homeownership rates — particularly in the Midwest and Northeast — also carried significant HELOC books.

Unlike commercial real estate loans (concentrated in regional banks), HELOC risk was somewhat more evenly distributed between large national banks and regionals, reflecting the retail banking penetration that was a prerequisite for originating HELOC volume. For the largest banks, HELOC stress would manifest as consumer credit losses that, while individually small, could be meaningful in aggregate across millions of accounts.

CNBC reported that bank stress tests conducted by the Federal Reserve in 2025 included a severe adverse scenario with significant home price declines and rising HELOC delinquency — and that several large banks' HELOC portfolios showed meaningful but manageable losses under that scenario. The stress tests suggested that HELOC losses were unlikely to be systemically dangerous for the largest institutions, but could be materially negative for earnings and could constrain the equity that banks needed to maintain lending standards.

For homeowners with HELOCs, the practical takeaway from rising delinquency rates and tightening lender behavior was straightforward: the home equity line that had seemed like an infinitely patient source of low-cost liquidity was now a two-way door, and the direction it opened in depended substantially on where home prices went next.
