On March 11, the U.S. spot Bitcoin ETF recorded a net inflow of $115 million, marking the third consecutive trading day of positive inflows and bringing the total rebound for March to approximately $1.56 billion. This trend coincides with Bitcoin's resilience amid the Iran conflict, a shift in its correlation with gold, and structural discussions on why significant capital inflows have not yet substantially boosted coin prices.
Three Days of Inflows Signal ETF March Reversal
Bloomberg ETF analyst Eric Balchunas noted that nearly all Bitcoin ETFs have turned to net positive flows year-to-date, which is a noteworthy data point considering the asset is down 22% year-over-year.

The correlation calculations are changing in real-time. Bitcoin's correlation with gold shifted from -0.49 to +0.16 within a week, indicating that the market may be starting to view these two assets as beneficiaries of a weak dollar rather than opposing risk trades. BlackRock's IBIT rose 3.75% over five days, while the iShares Expanded Tech-Software ETF (IGV) fell 2.45% during the same period.
Structural Gap Between ETF Inflows and Spot Prices
A puzzle remains: despite $1.56 billion flowing into the spot Bitcoin ETF this month, prices have only seen a slight increase. As of the time of writing, Bitcoin's trading price was $69,830, still 44.6% below its all-time high of $126,080 set in October 2025.
Analysts wrote: “The ETF has grown, but the actual BTC price hasn’t risen because there’s no buying pressure in the spot market.” “This could make BTC prices feel ‘stagnant’ or suppressed.” This mechanism typically has minimal impact on the market but can cause temporary price dislocations during periods of significant capital movement, which is the pattern visible in March's data.
Three Signals of Institutional Shift
The ETF reversal is not occurring in isolation. Three parallel developments help gauge whether this capital rotation may signal future trends in the coming months.
First, the nature of this capital is different from previous cycles. Exchange balances remain relatively stable, while ETF custodians are accumulating. This is patient capital, not fervent capital. The institutional portfolio rebalancing in early March, combined with Bitcoin's technical consolidation in the $65,000 to $70,000 range, created an entry window that systematic allocators seem to have taken advantage of.
What to Watch Next
The sustainability of March's ETF reversal depends on whether IBIT can maintain its daily inflow pace. This fund has been the only consistent net buyer across the entire ETF space; historically, days when IBIT turns negative often drag the entire industry into outflows.
The shift in BTC's correlation with gold is also worth monitoring. If Bitcoin continues to trade in sync with gold during the conflict-driven dollar weakness, it will strengthen the argument for “digital value storage,” especially as institutional allocators are actively reassessing their risk frameworks.
