Global equity funds just recorded their strongest weekly inflow since early July. The strange part: investors did it while long-term U.S. borrowing costs were sitting near multi-decade highs.
Money came back to stocks this week. Not because borrowing got cheaper. It didn’t.
Global equity funds attracted a net $44.1 billion in the week to September 25, their biggest weekly inflow since early July, according to LSEG Lipper data reported by Reuters.
At the same time, long-term U.S. government yields stayed near levels markets have not seen in decades. The 30-year Treasury yield reached 5.5016% on Thursday, while the 10-year yield traded around 5.17% on Friday after touching roughly 5.22%.
IN 30 SECONDS
Investors are paying up for risk even though the risk-free alternative has become much more attractive.
That tension matters. When government bonds offer yields above 5%, stocks, property, private credit and other risk assets have to work harder to justify their price.
Yet money still flowed back into equities — and AI was one of the main reasons.
THE NUMBER THAT MATTERS
$44.1 billion.
That was the net amount investors put into global equity funds during the week. U.S. equity funds alone attracted $37.6 billion, their strongest weekly inflow in three months.
Technology funds received another $5.29 billion, the largest weekly inflow since late July.

This is not a clean “risk-on” story.
It is a market choosing between two expensive ideas at the same time.
Idea one: lock in unusually high yields from government debt.
Idea two: keep paying for future growth, especially where AI is still driving earnings expectations.
Reuters reported that Goldman Sachs strategists estimate AI investment is contributing almost half of S&P 500 earnings-per-share growth this year.
That helps explain why stocks can keep attracting money even while bond yields are sending a very different message about the cost of capital.
WHAT DOES THIS CHANGE?
For investors, the hurdle rate is higher.
A stock does not compete only with another stock. It also competes with a Treasury yielding around 5%.
For companies, expensive long-term borrowing can pressure valuations, financing decisions and expansion plans.
For households, the same rate environment can show up in mortgages, loans and other credit products.
None of those effects are automatic or identical. But the higher the risk-free return stays, the more every risky asset has to prove its case.
WHAT TO WATCH NEXT
- U.S. payrolls and inflation: both can reset expectations for the next Federal Reserve move.
- Treasury yields: whether the 10-year settles back below 5% or holds above it.
- AI earnings: whether revenue and profit growth keep validating the capital being committed.
- Fund flows: whether this week marks a lasting return to equities or just a short burst of optimism.
