The $18 Trillion Piggy Bank: American Homeowners Have Never Had This Much Equity

American homeowners now hold a record $18 trillion in mortgage equity, but that wealth remains tied to their properties until they sell or borrow against it. Home equity can provide financial flexibility, but borrowing against a home comes with real risks – Shutterstock

American homeowners are sitting on a record $18 trillion in mortgage equity, and that enormous number makes the nation’s housing market look a little like the world’s largest piggy bank. The Intercontinental Exchange reported in August 2026 that mortgage holder equity reached $18 trillion in the second quarter, setting a new record as home prices continued to rise in many markets.

But there’s a catch hiding inside that eye-popping number: home equity does not sit in a checking account waiting for someone to spend it. It represents the portion of a home’s value that belongs to the homeowner rather than the mortgage lender, and accessing that money usually means borrowing against the house, selling it, or waiting until the home eventually changes hands.
