The first money market fund (1971)
Bruce Bent and Henry Brown launched the Reserve Fund, letting small investors earn short-term interest rates on cash that had previously sat in non-interest-bearing accounts. It turned cash into an investable asset with same-day access.
Money market funds grew quickly as a substitute for bank deposits.
Cash management became a discipline of squeezing yield out of balances that still had to be available on demand.
The Uber pilot applies the same tradeoff to the hours when banks and funds are closed. The question is whether yield can continue past the Friday cutoff.
