American Express filed the monthly servicer certificate for its credit-card trust on 15 July, and the line most people look at reads 52.2926 per cent. That is the share of the trust’s opening principal balance repaid during June, and it is the highest figure in the trust’s filings going back to 2000, when the same measure read 9.49 per cent. Against June 2009, at 24.1790 per cent, it is 2.16 times higher.
The other big trusts point the same way. Chase does not print a payment rate at all, but its June servicer certificate gives $6.207 billion of principal collections against an opening balance of $11.975 billion, which is 51.83 per cent — the highest of its Junes since at least 2021. Capital One’s master trust prints 48.41 per cent against 16.23 in June 2009. Citi is at 41.93 per cent against 17.55. Bank of America, whose book is a different shape, prints 27.97 against 12.50. Synchrony, a retail-card issuer, is at 25.06.
Read as a statement about American households, that would be remarkable. It is not one, and the reason is in the same filings.
In June 2009 the five largest of these trusts held $327.2 billion of principal receivables between them. In June 2026 they hold $94.5 billion, a fall of 71.1 per cent. Over roughly the same period, the credit-card book of the large bank holding companies the Federal Reserve collects loan-level data from grew 66.1 per cent, from $571.0 billion in the third quarter of 2012 to $948.67 billion in the first quarter of 2026. The trusts have gone from being a serviceable proxy for the market to holding under a tenth of it.
They also do not hold a random tenth. Which accounts an issuer designates into a securitisation trust is the issuer’s choice, and the AmEx trust in particular has been reshaped: 25.99 million accounts at the start of June 2009 against 12.32 million now, a fall of 53 per cent. Monthly charges per account went from $293.68 to $1,060.05, principal repaid per account from $324.65 to $1,079.35, and the balance carried per account from $1,342.71 to $2,064.06. A pool of higher-spending accounts that clear more of their balance each month will produce a higher payment rate whether or not anyone’s habits changed.
The Federal Reserve’s supervisory data, which covers the banks rather than the trusts, gives the wider picture and it is far less dramatic. The share of large-bank card balances that revolve fell from 72.20 per cent in the third quarter of 2012 to 70.16 per cent in the first quarter of 2026 — two points over fourteen years. The share of accounts paying the full balance rose more meaningfully, from 26.37 to 36.93 per cent, a factor of 1.4. That is a real shift toward transactors, and it is a fraction of the doubling the trust series implies.
Two mechanical points belong with the numbers. American Express normalises its payment rate to a 30-day period, a convention visible in its filings as far back as 2000; the June 2009 and June 2026 periods were both 30 days, so no adjustment separates them. And the AmEx trust is charge-card-heavy by construction, which is part of why its rate has always sat above the others rather than a sign of anything that changed this year.
What the series can be read for is the trusts themselves. Their payment rate is the speed at which the collateral behind their notes turns over, and at above 50 per cent a month the pools are replacing themselves twice a quarter. That is a fact about a shrinking corner of the funding market, not about the country’s balance sheet.
