The proposal, however, could conflict with U.S. regulators, who want a switch from survey-based lending rates to transaction-linked indices to calculate the interest payable on corporate debt and underpin the global market in financial derivatives.

The top U.S. regulator told a conference in London last month alternatives based on market transactions should be used and a fixed date set for scrapping the existing Libor and Euribor benchmarks that are currently based on quotes from banks.
More than a dozen banks are under investigation by authorities in Europe, Japan and the United States over suspected Libor rate rigging between 2007 and 2010 and officials, including incoming Bank of England Governor Mark Carney, are weighing up reforms to safeguard its integrity.
