BTC fell to $76,828, while ETH dropped below $2,500 as investors positioned themselves ahead of the key Senate vote on the CLARITY Act and the Federal Reserve decision on Wednesday.

Bitcoin ETFs ended their outflow streak
Institutional demand returned at the start of the week. U.S. spot Bitcoin exchange-traded funds recorded $159.9 million in net inflows on September 14, ending four consecutive trading sessions of outflows.
According to data from FarSide Investors, the largest contribution came from BlackRock’s IBIT with $134.3 million, followed by Fidelity’s FBTC with $53.3 million. Morgan Stanley attracted $9.7 million, while Franklin Templeton’s EZBC added $4.6 million. ARKB was the only major fund with a negative flow, at $42 million.
The reversal comes after a significantly weaker previous week. Between September 8 and 11, Bitcoin ETFs lost a total of around $462.7 million, ending three consecutive weeks of net inflows.
This makes Monday’s inflow more significant as a signal of a shift in short-term positioning, but it is still not enough to offset last week’s outflows.
Ethereum continues to attract capital
For ETH, the picture remained more resilient. Spot Ethereum ETFs recorded $121.1 million in net inflows on Monday after ending the previous week with around $197 million in inflows.
BlackRock was again the leading buyer. ETHA attracted $80.5 million, while ETHB added $14.4 million, Fidelity’s FETH $8.9 million, TETH $6.5 million, and Grayscale ETH $16.2 million. The only negative flow was $5.4 million at QETH.
The difference between the two largest crypto assets in recent sessions remains telling. While Bitcoin funds experienced significant outflows, Ethereum continued to attract capital and recorded a fourth consecutive week of net inflows.
Solana and XRP also start the week with inflows
Smaller spot ETF markets also posted a positive session.
Solana funds attracted a total of $11 million, with $7.1 million flowing into Bitwise’s BSOL and another $3.9 million into Grayscale’s GSOL. This comes after a relatively weak previous week, when Solana ETFs recorded around $10.3 million in net inflows.
For XRP, inflows reached $11.26 million, entirely into Bitwise’s fund, according to the data provided. XRP was also one of the few major tokens in positive territory over the past 24 hours, rising 0.24% to around $1.39.
Hyperliquid ETFs recorded no capital movement on September 14 after $8.2 million in outflows during the final session of the previous week.
Thus, the start of the week shows relatively broad institutional demand rather than concentration solely in Bitcoin.
Two political tests could determine the next move
The divergence between ETF flows and prices comes just ahead of two potential market catalysts.
The Senate is scheduled to hold a procedural vote on the CLARITY Act on September 15, with 60 votes required to proceed to debate. A day later, the Federal Reserve will announce its interest-rate decision, while markets are already pricing in a high probability of a 25-basis-point hike.
This combination helps explain why the recovery in ETF demand has so far not translated into a rise in BTC. Institutional funds are buying again, but the short-term market is reducing risk ahead of two events that could simultaneously change regulatory and macroeconomic expectations.
If positive ETF flows persist after the decisions in Washington, the current divergence may prove temporary. However, if Monday’s inflow remains a one-session event, the four-day outflow streak preceding it will continue to weigh more heavily on the assessment of institutional demand.
