Stablecoin supply falls $6.66 billion as USDT supply contracts

By Elena Vasquez

DefiLlama reported a $7 billion downturn in market liquidity as total stablecoin supply fell $6.66 billion in the week ending Nov. 7, 2026; USDT supply dropped a record $3.1 billion that week. The reported figures marked the contraction as the steepest weekly decline for both the broader stablecoin market and USDT in 2026.

How large was the contraction?

The contraction extended beyond that week. Total stablecoin supply fell about $15 billion over the preceding 30 days by early November, while the overall stablecoin market cap stood roughly $21 billion below its May 2026 peak.

USDT supply declined by $6.6 billion across the prior two months. The headline compares that 60-day drop with the post-FTX contraction and says it was larger, although the report provides neither the earlier decline’s size nor a calculation for that comparison.

The report also cited Tether’s own attestation data as support for the broader slide. It does not specify which balance-sheet measure establishes that link, so the claim cannot be tested from the figures provided.

The decline is measurable and broad, but the report does not establish where the withdrawn liquidity went.

Did the dollar peg fail?

On Nov. 8, USDT traded at roughly $0.9989, while USDC traded near $0.99945. Neither token broke its dollar peg during the reported redemptions.

The redemptions settled at stable value, with no sign of panic selling in the observed data. That pattern supports an interpretation of controlled withdrawals rather than a crisis-driven scramble for dollar tokens.

Operationally, fewer stablecoins remained outstanding after the redemptions, reducing the dollar-denominated float available in the market. The report does not identify the venues, counterparties, or uses involved, so it does not show where the withdrawn liquidity went.

The evidence supports liquidity pressure rather than a dollar-peg failure.

What do Tether’s reserves show?

Tether’s attestation for Q3 2026, dated Sept. 30, listed $191.5 billion in assets against $183.5 billion in liabilities. It reported:

• Assets: $191.5 billion.
• Liabilities: $183.5 billion.
• Reserve buffer: $7.95 billion.
• Treasury bills, described as a large share of backing: $132.4 billion.

The $7.95 billion buffer was larger than the $6.6 billion reduction in USDT supply over the previous two months. On that dated snapshot, reported reserve coverage exceeded the full two-month contraction.

However, Sept. 30 predates the late-October and early-November redemptions. An attestation cannot establish what remained afterward unless the later asset and liability changes are disclosed. The report provides no subsequent balance sheet, detailed liquidity schedule, or asset breakdown beyond the stated Treasury bill holdings.

The September snapshot suggests capacity to absorb redemptions, but it cannot verify the position after the withdrawals.

What should the market watch next?

Weekly supply figures remain the first checkpoint because both the $3.1 billion USDT reduction and the $6.66 billion market-wide decline set 2026 records. Continued contraction would reduce the stablecoin float available across the market, although the report does not identify where that liquidity had been deployed.

The dollar peg remains the second. As long as USDT trades close to $1 and redemptions settle near parity, the available evidence describes liquidity rather than Tether solvency. The report gives no publication deadline for the next attestation, which will be the clearest test of post-redemption reserves and liabilities.

The next weekly supply reading is the first market-structure checkpoint, while no deadline has been set for the next attestation.
