We document a novel support mechanism by banks through coordinating the investments of their clients in their affiliated mutual funds that experience excessive withdrawals. New inflows from bank clients limit the adverse effects of financial distress on fund performance and further mitigate strategic complementarities in investor redemption decisions. Thus, banks serve as a coordination device for the investments of their clients and enable them to earn a premium from participating in this support mechanism. Overall, our results demonstrate the existence of a mutual support system within financial institutions and highlight the potential benefits of bank-affiliation for fund investors.
