The banking industry worldwide must aim for a faster, rather than slower, build up in capital, Glenn Stevens, governor of the Reserve Bank of Australia, will tell a US banking symposium this morning.In a talk at the Federal Reserve Bank of San Francisco's Symposium on Asian Banking and Finance, Stevens will stress the need to build capital before the post GFC recovery gives way to some form of recession."One would hope that by 2019 major financial institutions would not only have reached new international minima for capital, but would have risen above them," his planned speech says.2019 is the target date set by the Financial Stability Board for Basel III rules to be in force.Steven's speech describes Australia as "highly supportive of the way the chair of the FSB has structured the efforts around four key themes [including] increasing the resilience of financial institutions, which in the main means implementation of the Basel III standards for banks.""One would hope that balance sheets by that time would be at their strongest position for the cycle. "This is a reason to go faster, rather than slower, in accumulating capital to higher minima, while one can. This point is of some relevance to the discussion in my own country at present."
