Apyx’s apxUSD stablecoin dipped to 93 cents on Wednesday as Bitcoin tumbled below $63,000, but the protocol insists the depeg is working exactly as designed.
The drop spooked some holders who expected a tighter dollar peg, and social media chatter quickly turned to concerns about cascading liquidations across decentralized lending markets. Apyx responded with a lengthy post on X arguing that volatility is an inherent trade-off in a stablecoin backed by preferred equity rather than plain cash. “This is not a bug,” the protocol wrote. “It is the expected behavior of a stablecoin backed by preferred equity rather than cash deposits.”
That framing will strike some observers as convenient spin and others as refreshing transparency. Either way, the episode highlights a structural tension in the new wave of yield-bearing stablecoins: the same asset classes that generate attractive returns also introduce volatility that traditional cash-backed tokens avoid.
How Apyx’s Two-Token System Works
ApxUSD sits at the base of Apyx’s stack. It is the stablecoin that is supposed to trade at $1 and does not pay yield on its own. Users who deposit apxUSD into the protocol receive apyUSD, a savings token that accrues returns from dividends flowing in from the underlying collateral.
The collateral itself is unusual. Instead of holding only dollars or short-term Treasuries, Apyx buys preferred equity shares issued by digital asset treasury companies. The flagship holding is Strategy’s STRC, which carries a $100 par value and pays dividends that Apyx passes through to apyUSD holders. Short-term U.S. Treasuries and cash equivalents round out the reserve, providing some liquidity and diversification.
Because preferred equity makes up the majority of the backing, apxUSD’s market value is sensitive to swings in those shares. When STRC trades below par, the mark-to-market value of Apyx’s reserves declines, and arbitrageurs reprice apxUSD accordingly in secondary markets.
STRC’s Par-Value Swings and Mean-Reversion History
Strategy’s STRC has traded below its $100 par value four times since August 2025, according to Apyx. Each episode eventually resolved with prices bouncing back to par. The protocol points to that history as evidence of mean-reversion rather than permanent impairment.
Preferred shares carry structural features that help stabilize their prices over time. Issuers can raise dividend rates to attract demand, pulling the share price back toward par. Strategy has used that lever historically, Apyx noted. The implication is that patient holders who understand the asset class should treat these deviations as temporary.
Whether that logic holds in a prolonged bear market is another question. Mean-reversion works until it doesn’t, and crypto participants have watched plenty of instruments “always recover” until the day they don’t. Still, the four-for-four rebound record gives Apyx some ammunition when defending its design.
The Overcollateralization Buffer
Apyx maintains collateral in excess of apxUSD’s circulating supply. That buffer is supposed to absorb mark-to-market drawdowns before they meaningfully impact the peg. Users can monitor the collateral position against supply in real time through the protocol’s app dashboard.
Overcollateralization is a familiar concept in DeFi lending. Protocols like Aave and Compound require borrowers to post collateral worth more than their loans, creating a cushion that liquidators can seize if values fall. Apyx applies a similar idea to its stablecoin reserves: even if STRC drops, the excess collateral keeps the backing ratio above 100% for longer.
The exact size of that buffer matters. A 5% overcollateralization cushion absorbs a 5% drawdown in reserve value; a 20% cushion absorbs more. Apyx’s public statements did not disclose a specific ratio, though the protocol says the data is available on its dashboard. Observers tracking the depeg noted that apxUSD’s 7% deviation suggests the cushion was either thinner than expected or that the market simply overshot on the way down.
Morpho Liquidation Concerns Miss the Mark
Some traders worried that apxUSD’s slide could trigger cascading liquidations across Morpho lending markets, where apyUSD is used as collateral. Apyx pushed back on that narrative, explaining that its main apyUSD/apxUSD Morpho market uses an oracle tied to dividend accrual, not STRC’s spot price.
The distinction matters. If the oracle priced apyUSD based on STRC’s real-time market value, a sharp drop in the underlying could push loan-to-value ratios past liquidation thresholds, forcing automated sell-offs that compound the price decline. Because the oracle instead tracks dividend accrual, STRC volatility does not directly trigger those liquidations.
That design choice insulates the protocol from the worst reflexive spirals, but it also means the oracle price can diverge from what holders would actually receive if they tried to redeem or sell. Whether that trade-off is wise depends on your view of what a stablecoin should be. If you prioritize redemption-at-par over liquidation resistance, Apyx’s setup might feel uncomfortable.
Stablecoin Depegs in Bear Markets: A Recurring Pattern
Apyx is hardly the first stablecoin to slip during a broader market selloff. The 2022 bear market produced the spectacular collapse of TerraUSD, an algorithmic stablecoin that lost its peg entirely and wiped out tens of billions of dollars. More recently, smaller depegs have hit various yield-bearing and collateral-backed tokens whenever Bitcoin or Ethereum tanks hard enough to stress reserve values.
The difference with apxUSD is that Apyx telegraphed the volatility from the start. The protocol’s documentation and public statements describe the stablecoin as “influenced by the volatility in the underlying shares.” That’s not a post-hoc excuse; it’s the stated design. Whether users actually read and understood those disclosures before buying is a separate question.
Stablecoin regulation is evolving, and the distinction between cash-backed tokens and collateralized alternatives could become legally significant. The Bank of England has already signaled openness to revising sterling stablecoin limits, and U.S. lawmakers continue debating how to classify and supervise stablecoin reserves. Apyx’s preferred-equity model sits in a gray area that regulators may eventually scrutinize more closely.
What Happens if STRC Stays Below Par
The bulls’ case rests on mean-reversion: STRC has always recovered to $100, so it will again. But four recoveries over roughly ten months is a thin data set, and the environment matters. If Bitcoin enters a prolonged drawdown, Strategy’s treasury position weakens, and STRC could spend an extended period below par.
In that scenario, apxUSD would likely trade persistently below $1, and the yield on apyUSD might not compensate holders for the capital loss. The overcollateralization buffer would erode over time unless Apyx injected fresh capital or sold reserves to rebalance.
Apyx has not disclosed contingency plans for a protracted bear market. The protocol’s defense of the depeg focuses on historical precedent and structural features that encourage mean-reversion, not on what happens if those features fail. That’s a reasonable editorial choice for a crisis-communications thread, but it leaves the harder questions unanswered.
For now, apxUSD has recovered some ground as Bitcoin bounced to roughly $64,000. The stablecoin is no longer at 93 cents, though it remains slightly below $1. Traders watching the next leg of the selloff, if one comes, will have a live test of whether Apyx’s “feature, not bug” framing holds up under sustained pressure.
