Strategy USD Reserve Hits $1.4B as It Buys 520 BTC

Alongside the reserve increase, Strategy bought 520 BTC for $34.9 million during the week of June 15 to 21. That lifted total holdings to 847,363 BTC, according to the company’s 8-K filing covering the period.

Inside the $300 Million Reserve Increase

The figures come straight from the 8-K and a post from Strategy on X. The reserve now sits at $1.4 billion as of June 21.

Notably, the company said it plans to keep topping the buffer up. In its own words, Strategy “plans to continue replenishing the USD Reserve over time based on market conditions to support the credit quality of its Digital Credit securities.”

The exact breakdown of the $300 million increase is not public yet. Strategy has not detailed which share sales settled into the reserve, so the precise mechanics remain unclear for now.

Why the Strategy USD Reserve Exists

The reserve is not a Bitcoin fund. Strategy set it up on December 1, 2025, as a pool of cash earmarked for one job.

According to the filing, the USD Reserve is “a management designated portion of Strategy’s liquidity intended to support the payment of dividends on Strategy’s preferred stock and interest on its outstanding indebtedness.” In plain terms, it pays the bills that demand dollars.

That matters because Strategy’s preferred shares pay cash dividends, not Bitcoin. A visible cash backstop means the company can meet those payments without selling BTC at a bad moment. As a result, a bigger reserve directly props up the credit quality of its preferred stock.

A Smaller Buy, Funded by Share Sales

The Bitcoin purchase itself was small by Strategy’s standards. The 520 BTC came in at an average price of $67,068. The company used proceeds from at-the-market share sales to fund it.

By comparison, total holdings now carry a cost basis near $64.10 billion, or roughly $75,651 per coin. With Bitcoin trading around $64,699 on June 22, that average sits above spot. So the firm is buying less and guarding liquidity more.

For context, BitcoinTreasuries.net had logged 846,842 BTC as of June 15. On-chain trackers such as Arkham Intelligence map the bulk of the stash across custody addresses. A large share sits at Fidelity.

STRC, Digital Credit, and the Dilution Debate

The reserve exists mainly to serve Strategy’s Digital Credit program. That program is a suite of perpetual preferred stocks, led by $STRC, plus $STRD, $STRK, and $STRF.

$STRC carries a $100 stated value and a variable dividend, currently 11.50% a year in semi-monthly cash. The rate adjusts monthly to nudge the stock toward par, as the company explains on its STRC learn page. Lower prices automatically push the effective yield higher.

Recently, $STRC has traded below par, near $89, lifting its effective yield toward 13%. Michael Saylor, the executive chairman, has said he wants to make STRC “the best credit instrument in the world.”

Still, skeptics push back hard. Critics on X argue that repeated share sales dilute common holders. The mNAV premium is thin, at about 1.12. They also question whether dividend coverage holds if Bitcoin corrects sharply. None of this is financial advice, and both readings deserve weight.

What the Strategy USD Reserve Move Signals Next

For now, the company’s dashboard points to roughly 9.8 months of dollar coverage for its dividend and interest obligations. That cushion, plus the pledge to keep refilling it, frames a clear shift in posture.

In short, Strategy looks less like a pure accumulator this week. It looks more like a credit issuer protecting its payouts. Whether the firm leans on more share sales, or ever trims BTC to fund dividends, stays an open question. The next filings may answer it. Readers tracking the Strategy USD Reserve should watch the weekly 8-Ks and the company’s purchase history for the next move.
