Regulators released long-awaited rules on Thursday morning that aim to restrict how big financial institutions can pay their top executives.

The new limits on banker bonuses would make the highest-paid employees at the biggest banks wait at least four years to receive parts of their annual pay. If the proposals are completed in the coming months, banks would also have to reclaim bonuses from bankers who take risks that lead to big financial losses.

The regulators are responding to an uproar of criticism over Wall Street’s pay practices after the biggest American banks had to take government bailout money during the 2008 financial crisis. That public anger has been rekindled during the 2016 presidential campaign season, putting pressure on regulators to tighten their oversight of Wall Street.

The new rules on executive pay grew out of the 2010 Dodd-Frank financial overhaul, but it has taken years to put them into practice, even though President Obama has pushed regulators to complete them. The administration is running out of time to get rules approved before a new president is elected.
