Investment banks are struggling in a high-interest-rate world

Shareholders like profits: a steady stream of income they can count on, quarter after quarter. The earnings America’s biggest banks make, however, are often pushed around by the volatility of the economy they serve. If the economy accelerates, demand for loans takes off; if it slows, bankers must set aside provisions for bad loans. Investment banks’ trading businesses tend to do well in times of volatility and uncertainty, but their advisory services sell best when markets are healthy and stable. Bank bosses must try to balance their exposure to these forces.
