Morgan Stanley’s MSBT added $61.67 million, while Bitwise’s BITB recorded $21.56 million.
Meanwhile, Grayscale’s GBTC and its newer Bitcoin fund posted smaller inflows of $3.34 million and $3.06 million, respectively.
Capital remains concentrated among the largest funds. IBIT held about $68.29 billion in net assets, compared with $15.51 billion for FBTC and $11.01 billion for GBTC.
The surge followed a volatile period for the funds as spot Bitcoin ETFs recorded $450.33 million in outflows on Sept. 15 and another $295.98 million on Sept. 16 before demand returned with $159.45 million in inflows on Sept. 17 and $433.03 million on Sept. 18.
September’s cumulative ETF inflows have now reached $1.31 billion, which follows $3.52 billion of inflows in August and a mixed performance earlier in the year.
January recorded $1.61 billion in outflows, while February saw withdrawals of $206.52 million.
March and April posted inflows of $1.32 billion and $1.97 billion, respectively, before outflows accelerated to $2.43 billion in May and $4.51 billion in June. July recorded $172.43 million of inflows.
Bitcoin hits its highest level since January as an $844m short squeeze boosts BTC
The rally was also supported by heavy short liquidations, with more than $844.20 million in crypto short positions liquidated over 24 hours, compared with $212.92 million in long liquidations.
Notably, Bitcoin accounted for more than $535.28 million of the short liquidations, which led it to briefly reach $87,374 on Sept. 21, its highest level since January.
When short positions are forcibly closed, traders must buy back the asset, adding upward pressure to the market. The resulting buying can trigger further liquidations, creating a short squeeze that amplifies an already strong move.
Also, large buyers are accumulating more bitcoin as Strategy announced the purchase of another 950 BTC, bringing its reported holdings to 846,000 BTC.
Crude oil prices fell sharply after signals from Qatar and U.S. President Donald Trump suggested diplomatic talks with Iran could resume.
WTI dropped toward $91.59 a barrel, easing concerns that prolonged Middle East disruptions could push energy prices higher and fuel inflation.
Broader market sentiment also improved on signs that the U.S. and China could extend their trade truce. The prospect of reduced pressure on global trade has added to the risk-on environment supporting Bitcoin and other major cryptocurrencies.
The total crypto market cap stood at just below $3 trillion at the time of writing, up about 4.3% over the previous day.
However, rising futures open interest shows leverage is building alongside the recovery.
CryptoQuant’s Julio Moreno said Monday that Bitcoin had moved above its 365-day moving average, which he described as the final signal needed to confirm a new bull market.
The next test is whether Bitcoin can hold above $85,000 and challenge resistance near $88,761.
A sustained move above that level could strengthen the recovery, while rising leverage and an RSI near 70 leave the market vulnerable to sharper pullbacks if buying momentum fades.
