US ETF inflows shatter 2025 record early

Inflows into US-listed exchange-traded funds have already surpassed the 2025 full-year record of $1.52 trillion, reaching $1.54 trillion by the end of September. This figure, covering only US-listed funds, highlights the accelerating growth in ETF adoption.

Record-Breaking Inflows

Equity funds led the charge, attracting over $1 trillion, while fixed income products followed with more than $469 billion. Reuters reported that State Street Investment Management forecasts a total of $2.3 trillion in inflows by year-end, showing the sustained momentum in ETF investments. Matthew Bartolini, global head of research strategists at State Street, noted that mutual funds continue to face persistent outflows, further emphasizing ETFs’ dominance.

Sector and Geographic Trends

Among equity sectors, technology funds saw the largest inflows, exceeding $59 billion, driven by enthusiasm for AI and strong earnings. In contrast, financials experienced outflows of more than $3.8 billion, reflecting sector-specific investor sentiment. Geographically, funds tracking US stocks dominated with $655 billion, followed by international developed markets at $150.4 billion, showcasing the global appeal of US equities.

The Vanguard S&P 500 ETF, the largest ETF in the world by assets under management, had gained more than 13% so far this year as of Friday morning, according to Reuters. Enthusiasm for AI and strong earnings pushed US stocks to record highs earlier this year, while inflation fears arising from the US-Iran conflict and soaring bond yields spurred volatility last month.

Rebalancing and Regulatory Developments

A Goldman Sachs report estimated that US pension funds would sell $33 billion in stocks to rebalance allocations, with those projections ranking the just-completed third quarter in the 98th percentile of historical estimates in absolute dollar terms since January 2000. Jordan Jackson of JP Morgan Asset Management noted signs of rebalancing, with investors increasingly buying bonds to realign portfolios. He emphasized that the scale of rebalancing this quarter is historically significant due to heightened volatility and deviations from target allocations.

Meanwhile, the US Treasury and IRS issued guidance on Section 351 exchanges, clarifying that conversions to avoid tax “don’t work under existing law”, according to Treasury Secretary Scott Bessent. A Bloomberg analysis found that $22 billion in ETFs had been created for tax deferral, avoiding up to $6.5 billion in capital gains. The IRS and Treasury are requesting comments on the notice by October 28, signaling a crackdown on tax avoidance strategies in the ETF space.
