Active bond mutual funds record first outflows in months, and $12B in ETF inflows masks the shift
As seen on the 24/7 Wall St. homepage on September 28, 2026.
The $12 billion that went into bond ETFs is masking the first active mutual fund outflow in months, and if redemptions accelerate those managers turn into forced sellers into a market already thin on liquidity.
Active bond mutual funds saw outflows for first time in a while in week ending 9/18 (so this doesn't count last week i'm sure its equal or worse). Conversely, bond ETFs took in $12b so more than offsets for now. But these MFs will be forced sellers of bonds if outflows pick up https://t.co/v95kgPuDkK

For the week ending September 18, active bond mutual funds posted outflows for the first time in an extended stretch, a threshold that Bloomberg Intelligence's Eric Balchunas flagged as a meaningful break in trend. Balchunas noted that the data does not yet capture the following week, which he expects to be equal or worse.
Bond ETFs absorbed $12 billion in that same period, more than offsetting what left the mutual fund side for now. That cushion, though, is doing the work of masking a structural shift in where fixed-income investors are choosing to park capital.
The more consequential risk sits inside the mutual funds themselves. If redemptions accelerate, those managers become forced sellers of bonds, pushing supply into a market at a moment when that pressure is hardest to absorb.
The week of September 18 looks like the early signal rather than the event itself. Balchunas said he is confident the subsequent week's numbers are at least as bad, meaning the trend investors need to monitor is still developing rather than resolved.
