Emerging markets such as Brazil and Turkey swooned over the Federal Reserve’s plans to cut back bond purchases. Banks say regulators are balkanizing finance by requiring each local affiliate to have the capital to stand on its own.

Leaks about surveillance by the U.S. National Security Agency have caused hard feelings among allies and rivals alike, with the spying scandal hurting U.S. suppliers of cloud computing as countries opt to keep data based at home.
