Fresh capital flowed back into U.S. spot Bitcoin ETFs at the start of the week, with Monday delivering the strongest single-day inflow in over a month and a half.

Data from SoSoValue showed that the group of funds pulled in $471.3 million in net inflows, spread across six issuers. 

BlackRock’s IBIT led the day with $181.9 million, followed by Fidelity’s FBTC, which brought in $147.3 million. Meanwhile, ARK Invest and 21Shares’ ARKB added another $118.7 million. Additional inflows were also recorded across products tied to Grayscale, Bitwise, and VanEck.

Monday’s figure stands as the highest daily intake since Feb. 25, when net inflows reached $506 million. The rebound effectively erased the $173.7 million in net outflows recorded on April 1, signaling a quick turnaround in investor positioning.

Beyond Bitcoin, spot Ethereum products also recorded $120.2 million in net inflows, which marked the highest daily total since the middle of March.

According to market pundits, these inflows could continue to offer structural support for Bitcoin and help it move beyond its current range. However, the ongoing macro uncertainty could pressure price action and limit any sustained upside.

Tensions between the United States and Iran have stretched into a second month, with no clear path toward de-escalation. Donald Trump has set an April 7 deadline for Iran to reopen the Strait of Hormuz, a critical route that has remained shut for weeks and contributed to rising global oil prices.

Trump warned of a “complete demolition” of Iran’s power plants and bridges if the demand is not met, a statement that has added to concerns around further escalation.

For now, Bitcoin is expected to remain sensitive to macro conditions. If tensions in the Middle East cool, it could help spur a return of risk-on sentiment.
