BlackRock’s head of digital assets says the macroeconomic case for Bitcoin is becoming stronger after the firm’s spot BTC ETF, IBIT, recorded exceptional trading activity during a strong week for the cryptocurrency.
Robbie Mitchnick, BlackRock’s digital-assets chief, said Bitcoin’s broader economic appeal is gaining momentum as investors increasingly focus on fiscal risks and the outlook for traditional markets.
IBIT posted its highest trading volume ever during a positive week since launching in January 2024. TradingView data showed the ETF’s performance closely followed Bitcoin’s roughly 23% weekly increase.
Mitchnick told CNBC that growing U.S. debt and budget deficits remain significant concerns for investors. He argued that renewed focus on fiscal problems could increase demand for scarce assets such as Bitcoin and gold.
He also highlighted Bitcoin’s recent strength compared with traditional markets. Equities have lagged Bitcoin and gold, while fixed-income markets have remained volatile, reinforcing the argument that BTC is developing a distinct role as a store of value.
That view is increasingly shared by market analysts who have raised concerns over the long-term path of U.S. government debt. Persistent fiscal pressure could encourage financial repression, potentially directing more investment toward hard and limited-supply assets.
BlackRock is directly involved in this trend through IBIT, the world’s largest spot Bitcoin ETF. The fund has attracted roughly $63 billion in capital since its launch.
During the latest week, approximately 439.5 million IBIT shares changed hands as Bitcoin rallied and investors continued adding money to the ETF. The fund’s overall volume record remains above 700 million shares, set in the week ending Feb. 6 when Bitcoin dropped toward $60,000.
The combination of heavy volume and strong inflows during a rising market suggests that institutional investors were actively increasing exposure rather than the activity being driven mainly by short-term speculation or retail traders.
IBIT gained 22.59% to $43.68 over the week, its strongest weekly performance since February 2024. The ETF also attracted approximately $1.33 billion in net inflows.
SoSoValue data shows IBIT has collected around $2.64 billion in net inflows so far this month, its strongest monthly total since October 2025.
