Regulators told the world's derivatives market that it must find a common approach for dealing with a sudden death of Libor, the interest rate benchmark used for pricing contracts worth more than $300 trillion globally. Libor became discredited after big investment banks were fined billions of dollars for trying to rig Libor. The London Interbank Offered Rate (Libor) is slowly being replaced with rates compiled by central banks, including Federal Reserve, the European Central Bank and the Bank of England. Britain's Financial Conduct Authority (FCA) has said that Libor is expected to cease after the end of 2021. In preparation for the change, the Financial Stability Board (FSB) said that a "pre-cessation trigger" should be inserted into terms for new derivatives contracts.
