Strategy's $1.45 billion preferred-share buyback program accounted for more than 20% of weekly trading volume in its variable-rate preferred stock (STRC) throughout September, raising questions about market liquidity as the issuer approaches the limit of its $2 billion buyback authorization.
Heavy Issuer Support Drives STRC Volume
According to a research report by digital asset firm Keyrock, Strategy's repurchases reached approximately 28% of STRC's weekly volume during the week of Sept. 8 before settling just below 20% in early October. The company, founded by Michael Saylor, had used roughly $1.45 billion of its $2 billion repurchase limit as of Oct. 4, leaving $547.2 million available. The program helped STRC recover from mid-$70s lows in June to $99.50, nearing its $100 reference price.
STRC ranks among the most active preferred securities in the market, averaging $150 million (and up to $152 million) in daily turnover. Keyrock noted that STRC absorbs about $28 million in trading volume before its price moves 10 basis points (0.1%). In contrast, Strive's SATA and Strategy's fixed-rate preferred instruments hold less than $3 million in market depth. Under standard conditions, liquidating a $50 million STRC position at a 20% daily volume execution rate takes less than two trading days, compared to five days for SATA and six to eight weeks for Strategy's fixed-rate preferred shares.
- Issuer Volume Contribution: Strategy buybacks represented 20% to 28% of weekly STRC trading volume during September.
- Cap Approaching Limit: Only $547.2 million remains of the firm's $2 billion buyback allocation as of Oct. 4.
- Liquidity Sensitivity: STRC market depth drops up to 8x when trading discounts widen beyond 6% from its $100 par value.
- Treasury Capital Shift: Strategy spent $176.3 million repurchasing STRC between Sept. 28 and Oct. 4, while spending $28.7 million to acquire 334 Bitcoin.
Price Parity Deterioration and Capital Allocation Tension
Keyrock found that STRC liquidity deteriorates sharply when prices stray from the $100 reference level. On the worst 10% of trading days, estimated market depth within a 10-basis-point move drops from $28 million to $6.5 million. Liquidity is four times lower when trading 1% to 3% away from par, and eight times lower when the deviation exceeds 6%. The correlation between distance from par and market illiquidity measured 0.43, compared to 0.10 for the magnitude of Bitcoin's daily price moves.
Capital allocation data shows Strategy deployed $176.3 million to repurchase STRC between Sept. 28 and Oct. 4 ($102.6 million in late September and $73.7 million in early October), drawing $154.1 million from cash reserves. During the same period, Strategy bought 334 Bitcoin for $28.7 million, using $13 million in cash. As market participants track institutional treasury strategies alongside updates like Citi raising its Bitcoin target to $113,000, the disparity highlights how heavily Strategy prioritizes preferred market support.
Why It Matters
Strategy's reliance on self-funded buybacks highlights a vulnerability in its market infrastructure for preferred stock. If the company exhausts its remaining $547.2 million repurchase authorization without expanding the cap, high-frequency traders and arbitrageurs supporting liquidity at $100 may pull back. This could leave STRC prone to severe price discounts and lower liquidity, potentially forcing Strategy to choose between supporting its financing instruments or maintaining direct Bitcoin acquisition.
