Stablecoin apxUSD Depegs: DeFi Faces Preferred-Share Collateral Risk

Apyx's apxUSD fell below its $1 reference on June 4, briefly touching $0.93 during the selloff, according to a Bitget report. The 24-hour range hit $0.9094 to $0.9984, with apxUSD trading around $0.9176 and volume surging to roughly $74.6 million. Bitcoin dropped 5.77% in the same period, but the depeg revealed something more structural: a synthetic dollar backed primarily by Strategy's STRC preferred stock, a publicly traded equity instrument.

Unlike traditional stablecoins such as USDC, which hold reserves in cash and Treasuries, apxUSD uses STRC as its core collateral. Apyx describes it as a "synthetic dollar" backed by a basket of Digital Asset Treasury preferred shares, with cash and Treasuries as a liquidity buffer. However, the protocol's own risk section warns that apxUSD may trade above or below $1, making the June 4 move a design feature, not a bug.

apxUSD is not a typical stablecoin: its peg depends on the behavior of a preferred equity instrument under market stress.
