WASHINGTON — Several regulators have dropped pursuit of a long-running plan to restrict bonuses on Wall Street, as part of a wider effort to stop working on unfinished rules put in place after the financial crisis.

Government agencies, including the Securities and Exchange Commission and several banking regulators, were directed under the 2010 Dodd-Frank law to develop compensation rules intended to curb excessive risk taking. Former President Barack Obama, during his last year in office, personally urged regulators to finish the rules before his term ended.
