Strategy's $1.45 billion buyback spree now drives most STRC trades, leaving the market exposed if company support dries up or slows.
Trading in STRC variable-rate preferreds has turned into a one-sided affair. Strategy's buyback program now props up the market, but the setup leaves a glaring question: what happens if the company steps back?
Keyrock's latest research lays out the numbers. Throughout September, Strategy's own repurchases made up over 20% of weekly STRC trading, peaking at 28% in the week of September 8. Even after dipping below 20% in early October, the company's hand still shaped the order book. By October 4, $1.45 billion had already been spent from a $2 billion buyback authorization, leaving just $547.2 million in capacity. At the current clip, that pool could dry up in three weeks. The company has raised the limit before, but there's no guarantee it will again. SEC filings show that between September 28 and October 4, Strategy bought back about 1.77 million STRC shares for $176.3 million-$102.6 million in the last days of September and $73.7 million in early October.
During the same period, Strategy spent over six times more on STRC buybacks than on Bitcoin purchases, acquiring 334 BTC for $28.7 million while its total Bitcoin holdings reached 848,000 BTC.
STRC's price has clawed back from the mid-$70s in June to nearly $99.50, closing in on its $100 reference. But that rebound rests on buybacks that Strategy can pause or end at will. The company's support isn't bottomless, and the market's dependence on issuer activity is now impossible to ignore. The buyback program doubled from $1 billion to $2 billion on September 8, but after the latest round, only $547.2 million remains, according to regulatory filings.
STRC averages $150 million in daily trading, putting it at the top of the preferreds market for activity. Keyrock's analysis found the instrument can handle $28 million in trades before moving 10 basis points-far deeper than Strive's SATA or Strategy's own fixed-rate preferreds, which each absorb less than $3 million before a similar price shift. For big investors, a $50 million STRC position can be unwound in under two days at current volumes. SATA would take five days, and Strategy's fixed-rate preferreds could stretch to eight weeks.
But those numbers shrink fast if Strategy steps away. Without the company's buying, trading capacity drops to about 80% of reported volume, and it takes longer to exit large stakes. The report flags that trading near the $100 mark often comes from arbitrage and high-frequency desks reacting to issuer moves. If buybacks slow, these players may vanish, leaving the market to long-term holders and opportunists.
Strategy's STRC buybacks were funded with $154.1 million from dollar reserves and $22.2 million in interest income, while only $13 million from reserves was allocated to Bitcoin purchases during the same period. This highlights the company's prioritization of supporting its preferred securities over direct crypto accumulation.
STRC's liquidity swings hard with its price. On the worst 10% of trading days, depth within a 10-basis-point move collapses from $28 million to $6.5 million. When STRC trades 1% to 3% away from $100, it becomes four times less liquid. Beyond a 6% gap, liquidity drops by a factor of eight. Investors trying to exit during price dips can face steep losses, with capital hits quickly outpacing expected dividends. Keyrock calculated that a typical drop from par wipes out about seven months of dividends. The June plunge to the mid-$70s erased nearly two years' worth of coupon payments.
The report doesn't pin this pattern on Strategy's buybacks alone. Similar liquidity swings showed up before the program started, and STRC still outpaces its peers for tradability. Whether that edge holds without ongoing company support is another matter.
Strategy is now considering tweaks to its preferred-stock setup to draw more outside buyers. Shareholders will vote October 28 on changes that would bring daily dividends to U.S.-listed preferreds. If approved, STRC starts daily payouts November 2. The company claims more frequent distributions could steady prices and smooth out trading around dividend dates. Keyrock's research, though, points out that similar setups-like Strive's SATA-haven't automatically deepened liquidity.
During the week ending October 4, Strategy spent $176.3 million on STRC buybacks and $28.7 million on 334 Bitcoin. Of the buybacks, $154.1 million came from cash reserves. The company faces a choice: keep supporting the securities that fund its Bitcoin stash, or shift capital toward more Bitcoin, dividends, or debt. If buybacks keep running at this pace, the remaining authorization could run out fast.
The next few weeks will show whether independent demand for STRC can fill the gap as company buying fades. If not, the market risks a liquidity vacuum as buybacks wind down. This risk echoes warnings in recent analysis about how structural dependencies can magnify risk in crypto-linked products.
Keyrock's data makes one thing clear: STRC's liquidity edge is real but fragile. The market's depth and trading capacity depend on Strategy's willingness and ability to keep buying. As the buyback limit nears and structural changes loom, investors face the risk that liquidity could vanish quickly if company support fades. The next round of disclosures and the October 28 vote will show whether STRC can stand alone or stays tied to Strategy's balance sheet.
Keyrock reports STRC's average daily trading volume at $150 million, putting it among the most liquid preferreds. The instrument's ability to absorb $28 million in trades before a 0.1% price move stands out against similar products, which rarely offer more than $3 million in depth. These figures reflect trading in September and early October 2026.
Preferreds like STRC give companies recurring funding and investors regular income. Unlike bonds, they often have no set maturity and may let issuers defer dividends. Liquidity isn't a given, especially when trading is concentrated or issuer-driven. For investors, knowing how buybacks, dividend schedules, and market depth work is key to managing risk-especially when large positions can be tough to exit without moving the price.
