Institutional investors’ appetite for cryptocurrencies has set a milestone so far in 2026. As of the week ending September 25, spot Bitcoin ETFs recorded a weekly net positive inflow of $2.18B ($2,180 million), the highest figure seen this year and the largest cumulative volume since the week of October 12, 2025. This massive momentum occurred with bitcoin trading at $84,500, operating slightly above the ETF cost basis (or average entry price) of $84,250. The market reading is clear: Wall Street is buying every dip with conviction.
The Fed tightens credit, but Wall Street doesn’t slow crypto
The record in Bitcoin ETFs stands out especially when considering the macroeconomic backdrop of the previous week. The U.S. Federal Reserve raised its benchmark interest rate by 25 basis points. Under normal circumstances, tighter monetary policy strengthens the dollar and puts downward pressure on risk assets.
However, bitcoin responded with a direct rally that pushed the price to a high of $87,400 following the announcement. Certainty explains this price action: the Fed’s decision aligned completely with market expectations, reinforcing confidence in the monetary system and eliminating short-term uncertainty.
Geopolitics and Bonds at Highs: The Investor Risk Map
Despite record capital inflows, fund managers remain cautious due to two high-tension macroeconomic factors:
10-Year Treasury Yields: Trading above 5.20%, reaching peak levels not seen since 2007. Such high yields on sovereign debt present direct competition for any risk asset.
Oil Crisis in the Strait of Hormuz: Crude oil trades at $96 per barrel. Following a brief period of calm driven by Chinese requests to Iran to prevent Yemeni intervention (which had forced Saudi Arabia to suspend shipments to China), tensions escalated again. The United States formally rejected the Iranian proposal for a complete opening of the strait, increasing economic pressure on an Iran hit by inflation, unemployment, and the collapse of its crude exports.
Altcoins Rally: Ethereum, Solana, XRP, and HYPE Join the Party
The institutional green wave did not stop at bitcoin. Demand extended to major altcoins through their respective exchange-traded products:
Ethereum (ETH): Led altcoin inflows with a weekly net positive inflow of $690M.
Solana (SOL): Attracted a net positive inflow of $188M.
XRP: Consolidated institutional interest with net inflows of $76M.
Hyperliquid (HYPE): Captured $9.3M in weekly net inflows.
Together, global crypto ETF performance across all cryptocurrencies reached an impressive cumulative inflow of $4.26B over the past month, according to consolidated data from Coinglass.
Market Impact and Outlook
In the short to medium term, bitcoin’s ability to hold above the ETF cost basis ($84,250) determines the health of the bull market. Capital absorption amid high interest rates confirms that institutional investors view crypto assets as a store of value and a strategic hedge against global geopolitical turmoil.
