Completing the so-called "Basel III" reforms "represents a major milestone that will make the capital framework more robust and improve confidence in banking systems," European Central Bank president Mario Draghi said after the meeting, which brought together regulators and central banks from major advanced economies like the United States and the European Union as well as emerging nations such as China, India and Brazil.
They include compromises on how regulators treat the risks banks run from their lending business, from financial market activities and from "operational risks" ranging from human error to acts of God.
In particular, the deal puts an end to EU-US wrangling over how should be calculated the amount of capital banks should keep on hand to weather financial shocks.
And the supervisors and central bankers also pushed back deadlines, giving lawmakers time to implement the new global rules and banks time to prepare for their application.
Most of the changes are expected to only take effect from 2022.
