Barclays held 3.94 million shares of BlackRock’s iShares Bitcoin Trust ETF, worth about $187 million at Sept. 30, according to a third-quarter 13F filing. The position rose 48% from 2.66 million shares valued at approximately $88.5 million at the end of June. IBIT’s 41% price gain during the third quarter contributed to the increase in dollar value. Citigroup disclosed a new position of roughly $119 million in Fidelity’s Wise Origin Bitcoin Fund and increased its IBIT holdings by about 50% to 521,000 shares. Among early third-quarter filers, banks held $258 million of spot Bitcoin ETFs, up from $107 million in the previous quarter, raising their share of reported institutional holdings to 4.9% from 3.2%. Total institutional holdings rose to $5.25 billion from $3.35 billion, while investment advisers accounted for $3.5 billion, or 66.6%. The figures remain preliminary because remaining filings were due by Nov. 17, and the reports capture positions as of Sept. 30 rather than later price movements. The filings also do not show whether bank positions reflected proprietary strategies, client activity or other business needs.
