Investors continue to pile into money-market funds, driving the assets in those funds to a record amid tariff-related declines in the stock market. Assets in money-market funds hit $7.03 trillion for the week ended Wednesday, April 2, up from $7.01 trillion the previous week, according to the Investment Company Institute, an asset-management trade group. Money-market funds have been drawing in investor dollars because of their high yields and because they are seen as a kind of safe haven during periods of market volatility.
