Stablecoin Supply Contracts $6.7 Billion in a Week, the Steepest Drop of 2026

The aggregate supply of dollar-pegged stablecoins fell $6.66 billion over the seven days ending 7 November, settling at $292.31 billion — the steepest weekly contraction of 2026 and the deepest since the week Terra's UST collapsed in May 2022, according to DefiLlama's daily stablecoin series. Tether and Circle together accounted for $4.40 billion of the decline, or 66% of the total. Stablecoins are blockchain tokens built to track the dollar: issuers create new tokens when dollars arrive and retire them when holders redeem, so the aggregate count doubles as a running gauge of how much dollar liquidity sits inside crypto.

Neither token broke its peg. $USDT traded at $0.99892 and $USDC at $0.99945 on CoinGecko at 01:03 UTC on 8 November, meaning the dollars exited through redemptions rather than at a discount.

The decline is not confined to a single week. The series has now fallen for ten consecutive days, a run that began on 29 October, and the rolling seven-day change has been negative for 29 straight days. Over the past 30 days, supply is down $15.03 billion from $307.33 billion on 8 October. Friday's reading of $292.31 billion is the lowest since 24 September 2025, when the total stood at $291.68 billion. Measured from the 17 May peak of $315.54 billion, the market has shed $23.23 billion, or 7.36%, over 174 days.

For scale, $6.66 billion amounts to 2.28% of the outstanding stablecoin base, 0.44% of bitcoin's $1.52 trillion market value at the same moment, and 8.2% of the $81.07 billion in deposits DefiLlama counts across its 421 supported chains. A contraction of this size does not empty lending markets; it removes a layer of the dollar liquidity on which those markets sit.

Ten Straight Down Days and the Steepest Week of the Year

The daily series makes the run easy to trace. Supply stood at $303.25 billion on 23 October and held above $300 billion through 29 October, when the reading was $300.11 billion. It crossed below the following day at $299.70 billion, then slid to $298.96 billion, $298.36 billion, $297.62 billion, $296.01 billion, $295.13 billion, $294.55 billion, $293.73 billion and finally $292.31 billion. The three largest single-day drops came on 29 October (−$1.49 billion), 3 November (−$1.60 billion) and 7 November (−$1.42 billion).

Among the 311 rolling seven-day readings recorded in 2026, the figure for 7 November is the most negative of the year, and the seven worst readings of 2026 all fall inside the current run. Before this stretch, the sharpest weeks were 1 February at −$4.08 billion and 7 June at −$3.81 billion.

In percentage terms, the comparison with 2022 is less alarming than the headline implies. In the week to 15 May 2022, supply fell $27.4 billion against a $158.01 billion base, a 17.36% contraction. Last week's $6.66 billion equals 2.28% of the base — 7.6 times smaller in percentage terms. The 2022 episode was a run on issuers whose collateral was in question; the current one is a steady withdrawal from the two largest issuers, both of which are still redeeming at par.

Two Issuers Account for Two-Thirds of the Drop

$USDT's decline of $3.10 billion is 46.5% of the total, and $USDC's fall of $1.31 billion is 19.6%. Sky's USDS lost $864 million, World Liberty's $USD1 shed $357 million, BlackRock's BUIDL dropped $249 million and Global Dollar fell $217 million. Eight of the ten largest stablecoins shrank over the week; exactly two grew.

The concentration shapes how the contraction transmits. Tether and Circle are the two largest issuers, and their tokens are the default quote asset on most spot and derivative venues. When their supply falls, the effect lands on the shared order-book base rather than on a single platform losing deposits.

Tether's Own Attestation Points the Same Way

Tether's third-quarter attestation, prepared by BDO and dated 30 September, described USD₮ issuance as "broadly steady at $184 billion" across the first three quarters. An attestation of this kind is a point-in-time review of reserves by an outside accounting firm rather than a full audit. DefiLlama's series for the same date shows $183.84 billion — a $160 million gap that sits inside the normal difference between issuer reporting and on-chain aggregation. Against Friday's $176.997 billion, USD₮ is down $6.84 billion, or 3.87%, in the 38 days since that report.

The issuer's own numbers explain why the redemptions have not produced a discount. The attestation put the reserve buffer at $7.95 billion, up from $4.1 billion at the end of the second quarter, with total reserve assets of $191.5 billion and $132.4 billion in direct and indirect Treasury bill holdings. Against the $6.84 billion five-week drawdown, the buffer covers 1.16 times; against the $176.997 billion of USD₮ outstanding, reserves cover 108.2%.

Paolo Ardoino, Tether's chief executive, framed the buffer as a redemption tool rather than a profit line in the attestation release. "Our responsibility is to make sure USD₮ remains dependable when people need it most, including when markets and financial systems come under pressure," he said. "Generating $1.5 billion in net operating profit while maintaining nearly $8.0 billion in excess reserves gives us a strong foundation for that work." Tether reported $4.5 billion in net operating profit across the first three quarters, $1.5 billion of it in the third.

Circle's Steeper Slope on a Smaller Base

Circle's quarter shows a sharper decline on a smaller base. $USDC stood at $74.58 billion on 30 September and $70.60 billion on 7 November, a drop of $3.99 billion, or 5.35%, in five weeks. The company's third-quarter results reported revenue up 17% to $865 million, while reserve income fell 8%. Chief executive Jeremy Allaire pointed to distribution rather than balances in the company's release: "In Q3, we saw continued proof that institutions are building and expanding on $USDC." The same release disclosed a $100 million equity investment from Binance alongside a renewed partnership, and the Arc mainnet launch on 16 September.

Neither quarter reads as a distress signal — which is the point. The two largest issuers lost $4.40 billion of tokens in a week, and neither reported a reserve shortfall. Supply can fall because holders redeem, and that is a different event from supply falling because holders cannot.

The Long Tail Grew While the Leaders Shrank

$USDe's gain of $404 million and $RLUSD's gain of $270 million together offset 10.1% of the total contraction. Both differ structurally from the tokens that shrank: $USDe is a synthetic dollar backed by hedged derivative positions rather than bank deposits, while $RLUSD is issued by a company that also operates a payments network and settles on XRP Ledger as well as Ethereum.

Two tokens gaining is not proof of a rotation. Total supply still fell, which means most of the dollars that left the two largest issuers did not reappear elsewhere in the same quantity. What the split does show is where marginal demand went: toward instruments that pay a yield on the dollar rather than a token whose only promise is a peg.

What a $6.7 Billion Hole Does to Onchain Credit

A stablecoin is the unit in which onchain credit is denominated. Lending markets quote borrow rates in $USDT and $USDC, perpetual futures — derivative contracts with no expiry whose leveraged positions are held open through funding payments — settle in them, and treasuries hold them as the cash leg. When the supply of those tokens falls 2.28% in a week, three things follow mechanically, without any change in borrower behaviour.

First, USD-denominated TVL falls at the same rate. A protocol holding $1 billion of $USDC shows $977 million after a 2.28% contraction even if no contract changed hands. Second, the lendable float shrinks, so utilization rises for a given level of borrowing, and variable borrow rates follow utilization. Third, the same dollars are asked to do more work across venues, which is why a 2.28% supply move can register as a larger move in funding rates than its size suggests.

The run began on 29 October, the same day as the Binance breach that the exchange later said it had 98% replenished. The timing is worth naming and not overreading: a theft does not shrink stablecoin supply unless the stolen tokens are redeemed or burned, and neither issuer has linked the two events. The daily series also shows the decline accelerating after 4 November, with drops of $580 million, $822 million and $1.42 billion on consecutive days.

What the record supports is a demand story. Supply has fallen in every rolling seven-day window for 29 days, with bitcoin at $75,709 and ether at $2,233.87 on CoinGecko at the time of writing. Stablecoins are the cash leg of crypto positions; when the cash leg shrinks, gross exposure is usually shrinking too.

The Levels That Break or Confirm the Trend

Two readings matter for the coming week, and both come from the same daily series rather than from a chart pattern. A close back above $300 billion, the level the total held on 29 October, would be the first sign that the run has stalled. A print below $291.68 billion, the 24 September 2025 reading, would be a new 2026 low and the weakest level since at least September 2025, extending the drawdown past the range that has held all year.

Pace matters more than the level. Five consecutive seven-day readings have landed between −$3.5 billion and −$6.7 billion. A week that closes with a decline under $1 billion would be the first deceleration since 29 October, and would mean new issuance is absorbing redemptions. The data does not yet support a stronger claim than that.

For DeFi, the number to watch is the ratio between stablecoin supply and total value locked. At $292.31 billion of stablecoins against $81.07 billion of TVL, that ratio is 3.6 to 1. Watching it separates a dollar exit from a risk exit: if TVL stabilises while supply keeps falling, the money is leaving crypto entirely; if supply stabilises first, the withdrawal was a rotation out of risk within crypto.
