Strong inflows into U.S. spot bitcoin exchange-traded funds have not translated into a comparable move in bitcoin’s price, a dynamic analysts say is largely due to how ETFs operate behind the scenes.
Analysts at Bitfinex say investors have poured roughly $1.4 billion into spot bitcoin ETFs over the past five days, yet the cryptocurrency’s price has remained relatively stagnant. The reason, they argue, is that ETF inflows are often mistaken for immediate buying pressure in the spot market.
In remarks shared with CoinDesk, the analysts explained that the structure of ETFs can create a delay between the moment investors allocate capital and the point at which actual bitcoin purchases occur. As a result, the bullish impact of inflows may not appear in the price right away.
An ETF functions as a pooled investment vehicle that holds an underlying asset—such as bitcoin—while issuing shares that trade on stock exchanges like ordinary equities. Each share reflects a portion of the fund’s holdings. Since the debut of 11 spot bitcoin ETFs in the U.S. in January 2024, the products have collectively attracted more than $55 billion in inflows.
The mechanism that keeps ETF prices aligned with their underlying value depends on authorized participants (APs), typically large banks, broker-dealers, or market makers. When demand pushes an ETF’s trading price above its net asset value, APs can create new shares and sell them into the market to close the gap.
However, these participants often sell ETF shares before they acquire the underlying bitcoin. This practice effectively allows them to short the ETF shares first and then purchase the corresponding bitcoin later. Unlike most investors, who must borrow shares before short selling, APs are permitted under ETF rules to short shares quickly and complete the corresponding asset purchases hours later or even on the next business day.
Because of this timing gap, inflows into ETFs can increase even when immediate buying in the spot bitcoin market has not yet occurred. By the time those purchases are made, other selling pressure elsewhere in the market may offset the impact, limiting the upward effect on bitcoin’s price.
According to analysts at Bitfinex, this lag likely explains why ETF inflows have surged while bitcoin’s price has remained relatively range-bound.
“The result is that the ETF grows, but the actual BTC price doesn’t rise because there has been no buying in the spot market,” the analysts said, adding that the situation can make the asset appear temporarily “stuck.”
They noted that such mismatches typically have little long-term effect. However, during periods of market stress or unusual volatility, the gap between ETF demand and actual spot buying can briefly lead to pricing distortions in the market.
