The death spiral of the digital asset treasury

The product that defined crypto capital markets across 2024 and 2025 was not the ETF. It was the digital asset treasury. Public companies, led by Strategy, ran a single reflexive loop: issue stock at a premium to net asset value, buy crypto with the proceeds, let the story widen the premium, then repeat. In 2025 alone that loop raised roughly $86B for token purchases.

The only fuel this engine ever burned was one thing. The stock had to trade above the value of the crypto it held, mNAV above 1.0.

In the first half of 2026 the fuel ran out. Strategy's mNAV fell from about 2.0 at the middle of 2025 to roughly 1.5 in June and to about 0.62 by 13 July. The Ethereum treasuries BitMine and SharpLink now sit 91% and 96% below their highs. Most decisively, on 18 and 19 June, bitcoin backed "digital credit" preferred shares, Strategy's STRC and Strive's SATA, broke below par and failed the structure's first real stress test.

Calling today's discount a passing valuation adjustment understates it. Calling it a finished death spiral overstates it. What can be said plainly is this: the flywheel has begun to turn in reverse. The moment the premium disappears, the DAT loses its growth engine, and in a discount regime the rational move becomes selling crypto to buy back stock, which carries the pressure straight into the token. In NYDIG's phrasing, it is this same cycle running again, only backwards.

1  Why Now

The fragility of the DAT is an old argument. What changed in the last few weeks is that it moved from theory to observed fact.

Digital credit broke first. On 18 and 19 June, Strategy's variable rate perpetual preferred STRC traded as low as about $82.50 and Strive's SATA slipped into the low 90s against a $100 par. Strive's chief executive named the cause not as credit impairment but as leverage liquidation: positions borrowed against the preferreds turned into forced sellers on a small decline. The first stress in this roughly $10B market taught the market that these instruments are hybrids with no par redemption mechanism and no collateral behind them.

The sell side made it official. On 3 July, JPMorgan warned that retail holders of STRC faced deepening losses. An institutional desk had put a name to the risk in the DAT credit stack.

The "never sell" story collapsed. To meet debt and dividend obligations, Strategy began selling BTC, breaking the single promise that anchored its narrative. The company now reads less like a compounding machine and more like a static, levered BTC position carrying roughly $1.5B a year in cost. The treasury company Empery Digital sold 1,400 BTC to fund a pivot into AI. The turn from buyer to seller is now visible at the level of individual firms.

mNAV fell through 1.0 across the board. Strategy at 0.62 on 13 July, BitMine and SharpLink already at a discount. NYDIG called Strategy well collateralized but flywheel dependent on market access, and in its second quarter review judged that leverage, not spot demand, is holding the bitcoin price up. Behind all of it: the worst month on record for spot bitcoin ETFs, near $4.5B of net outflows in June.

2  Is This A Death Spiral

The question is whether today's discount is an ordinary valuation adjustment in a weak market, or a structural death spiral in which forced selling drives the token down, which deepens the discount, which forces more selling.

The answer is both, but the structure tilts toward the spiral. Three reasons.

First, the DAT's growth engine depends on the premium and nothing else. A treasury can raise crypto per share in only three ways: issue stock above NAV, add leverage, or trade the book actively. The overwhelming majority relied on the first. Below 1.0, issuing stock destroys existing holders rather than growing them, so the loss of the premium is not a price move, it is the business model switching off.

Second, the premium comes from story rather than fundamentals, and story tracks price. Strategy itself traded at no premium or a steep discount through 2022 and 2023. If the premium is tied to price, then a price correction takes the premium with it, which cuts issuing power, which pushes price down again. It is the 2021 GBTC arbitrage reversal in a new shell.

Third, in a discount regime selling crypto is the rational choice. When the stock is cheaper than NAV, selling tokens to repurchase shares is the only way to lift crypto per share. If management will not do it, activists will force it. Strategy's BTC sales and Empery's disposal show the logic already at work. The channel that carries selling from stock into token is open.

The reason not to call it settled is just as clear. Strategy's collateral remains sound, with BTC holdings well above its debt. June's break was a leverage liquidation, not a credit failure. Preferred dividends are still being paid, and new entrants kept coming into the credit market after the shock. The trigger has been pulled. A pulled trigger does not guarantee the gun fires. What decides it is price.

3  The DAT Life Cycle

To turn scattered headlines into one model, read the DAT as a four stage life cycle with mNAV as the master variable.

The master variable is mNAV alone, market capitalization divided by the value of the crypto held. 1.0 is the line between life and death, and because the ratio tracks price, the whole model is reflexive.

Three triggers set the collapse in motion:

• Price correction. The premium is tied to price, so a token decline pulls the premium down with it.
• Traditional demand drying up. A DAT works only while its investors are making money. When new inflows stop, the premium has nothing to stand on.
• Leverage liquidation. Positions borrowed against preferred and credit instruments turn into forced sellers on a small decline, as June showed.

The key insight is that leverage is not the main risk. Even NYDIG reads Strategy's debt coverage as sound. The real risk is that the market simply stops paying two dollars of stock for one dollar of crypto. The debt is a red herring. mNAV is the body.

4  What We Are Watching

• Whether digital credit reclaims par. Do STRC and SATA hold $100, or keep slipping. New issuance in the $10B credit market is the first gauge of system stress.
• Treasury companies turning net seller. Further BTC sales from Strategy, and whether cases like Empery multiply from single events into a sector wide shift. That aggregation is the confirmation of a reverse flywheel.
• Activist campaigns aimed at firms that cannot reclaim mNAV 1.0.
• The Ethereum treasuries, BitMine and SharpLink. ETH around the $2,000 line and how far their treasury buffers erode. More volatile than the bitcoin DATs, and a leading indicator.
• The premium on new DAT listings. How often a fresh listing trades below par on debut.
• ETF flows. Whether capital returns to the spot ETF, the DAT's substitute. Renewed ETF inflows would add further downward pressure on DAT premiums, not relieve them.

5  Close

The DAT was the largest piece of financial alchemy of the cycle. Not regulation, not technology. Wall Street and public companies worked out how to turn a dollar of crypto into two dollars of stock, and the only catalyst was a premium the story manufactured. In the first half of 2026 the catalyst evaporated.

Whether this becomes a death spiral that pulls the whole sector down is not settled. Collateral is still sound, dividends are still paid, and June's break was a leverage liquidation rather than a credit failure. But the flywheel has started to turn in reverse, and the channel that carries selling from stock into token is now open. Next quarter the market learns whether 0.62 was the floor or a waypoint. The variable that decides it is, as always, price.
