US equity funds recorded outflows for a fourth consecutive week in the week to September 18, as rising crude oil prices heightened inflation concerns and expectations of a Federal Reserve rate hike added to investor caution ahead of its policy decision. US equity funds recorded net redemptions of $31.44 billion during the week, largely matching the $32 billion withdrawn a week earlier, LSEG Lipper data showed. Crude oil prices rose to four-month highs during the week, fueling inflation concerns and lifting Treasury yields, which weighed on growth-oriented funds.
