Governor of the Bank of England and former Governor of the Bank of Canada Mark Carney has described two approaches to global financial reform: shielding financial institutions from cyclic economic effects by strengthening banks individually, and defending economic cycles from banks by improving systemic resiliency. Strengthening financial institutions necessitates stronger capital requirements and liquidity provisions, as well as better measurement and management of risks. The G-20 agreed to new standards presented by the Basel Committee on Banking Supervision at its 2009 summit in Pittsburgh, Pennsylvania. The standards included leverage ratio targets to supplement other capital adequacy requirements established by Basel II. Improving the resiliency of the global financial system requires protections that enable the system to withstand singular institutional and market failures. Carney has argued that policymakers have converged on the view that institutions must bear the burden of financial losses during future financial crises, and such occurrences should be well-defined and pre-planned. He suggested other national regulators follow Canada in establishing staged intervention procedures and require banks to commit to what he termed "living wills" which would detail plans for an orderly institutional failure.
