Investors poured $60 billion into U.S. fixed-income ETFs in October, signaling renewed demand for bonds even as equity markets grappled with concerns over stretched AI valuations and elevated Treasury yields.

The inflows came during a volatile month for fixed-income markets, with bond yields climbing to multiyear highs in mid-October before retreating as stocks weakened. The 10-year yield had touched 5.37% during the month before settling around 4.93% by Oct. 30. The simultaneous demand for equities and bonds suggests investors are looking to diversify their portfolios rather than abandon risk assets altogether.

U.S. equity ETFs attracted $79 billion in October, while international equity funds gathered $34.5 billion, according to data aggregated by ETF.com. However, the $60 billion flowing into domestic bond ETFs highlights the growing importance of income-generating assets and liquidity amid market uncertainty.

MUB and SGOV Lead October Inflows

The iShares National Muni Bond ETF (MUB) and iShares 0-3 Month Treasury Bond ETF (SGOV) were among the biggest beneficiaries, attracting $6.13 billion and $4.51 billion, respectively.

MUB's October inflows represented approximately 11.3% of its assets, while SGOV continued to benefit from demand for short-term government securities.

The appeal of municipal bonds has strengthened as yields climbed. VanEck reported that AAA-rated municipal bond yields reached 4.58% at the end of September, their highest month-end level since October 2008.

For investors in the 24% federal tax bracket, that translated into a tax-equivalent yield of approximately 6.03%.

Are Investors Rotating Away From Equities?

The broader trend suggests investors are looking to lock in attractive income while managing exposure to volatile equity markets. However, October's $79 billion in U.S. equity ETF inflows indicates that demand for stocks remains strong.

For bond investors, the challenge is balancing attractive starting yields against the possibility of further rate increases. Longer-duration ETFs remain particularly vulnerable to price declines if yields climb again, while ultra-short Treasury funds offer lower interest-rate sensitivity but limited potential for capital appreciation if rates fall.

October's flows suggest investors are increasingly seeking income and diversification, rather than making a wholesale retreat from equities.
