In global ETF markets, 2024 data indicate that funds with OER reductions captured larger net inflows. Analysts see this as evidence that investors are increasingly fee-sensitive during volatile macroeconomic conditions. "Feels like today’s print was pre-traded with yesterday’s PPI," said analysts at JPMorgan, in a note, "and with the disinflation story intact, tomorrow’s retail sales [number] is necessary to assuage (or confirm) growth concerns."

It’s a key metric for evaluating funds or companies, especially in the ETF market. For example, S&P 500 ETFs with an OER below 0.15% are projected to outperform by 2-3% annually compared to peers with higher ratios, according to recent Morningstar data.
