[ by Melanie Gretchen ] The Financial Stability Board may extend the definition of 'too-big-to-fail' to include domestic lenders, clearing houses, and insurers, forcing them to abide by capital rules designed for the world’s biggest banks. Board chairman Mark Carney said following a meeting yesterday in Switzerland, that the FSB may introduce tougher rules for "shadow banks," when it assesses its work no later than March.  These include money-market mutual funds, special investment vehicles, credit hedge funds, securities lenders, and government-sponsored enterprises like Fannie Mae and Freddie Mac - whose failure could harm the global financial system. With regard to clearing houses, global regulators should be able to take decisions by June on the “appropriate form” of central clearers dealing with derivatives, the FSB said.  It will also create a group to examine cross-border disputes over rules governing banker pay. Currently, 29 banks around the world are subject to capital surcharges drawn up by the FSB in November for globally systemic financial institutions, including Deutsche Bank, BNP, and Goldman Sachs.  According to the financial regulator, there are many more institutions that may not be systemic on a global level - but are on a national level.  Mr. Carney expects the framework for these should be in place by the end of the year.
