Caution over midterms and AI cash burn drives surge in US money market fund inflows

Nov 6 (Reuters) – US money market funds posted their largest weekly inflow in six months in the week to November 4, as caution ahead ​of the US midterm elections and concerns ‌about rising AI spending and cash burn at major technology hyperscalers boosted demand for safe-haven assets.

Investors added a net $117.97 billion to US money market funds during the week, marking the largest weekly ‌net ​investment since May 6, according to ⁠LSEG Lipper data.

US equity ⁠funds attracted $14.81 billion in net inflows, reversing the previous week’s $6.54 billion net outflow, as declining energy prices and a fall in Treasury yields from their ​October highs supported sentiment.

Democrats won control of both the Senate and the House in Tuesday’s US midterm ⁠elections, raising concerns that increased ⁠regulatory scrutiny could curb the AI sector’s ​rapid expansion.

Those worries weighed on markets on Thursday, when the ​Nasdaq, S&P 500, and Dow Jones Industrial Average ‌fell 5.52%, 4.36%, and 3.44%, respectively.

Investors bought a net $10.35 billion of US large-cap funds in the week, $1.64 billion of multi-cap funds, and $422.77 million of small-cap funds, while ⁠selling a net $1.07 billion of mid-cap funds.

Among US sector funds, technology, industrials, and communication services recorded outflows of $160.23 million, $624.67 million, ⁠and $965.68 million, respectively. ‌In contrast, financials and healthcare attracted ⁠inflows of $1.3 billion and $1.09 billion, respectively.

US bond ​funds ‌secured inflows worth a net $7.31 billion, the ​highest in ⁠four weeks.

General domestic taxable fixed-income funds and longer-maturity government and Treasury funds recorded significant inflows of $2.72 billion and $2.66 billion, respectively. Investors also bought $794.32 million worth of short- to intermediate-term government and Treasury funds.
