US regulators 'find evidence' of banks fixing derivative rates.

The Commodity Futures Trading Commission (CFTC) is probing 15 banks over allegations that they instructed brokers to carry out trades that would move ISDAfix, the leading benchmark rate for interest rate swaps.

Pension funds and companies who invest in interest rate derivatives often deal with banks to insure against big movements in the ISDAfix rate or to speculate on changes to interest rate swaps

ISDAfix is published each morning after banks submit bids for swaps via Icap, the inter-dealer broker, in a number of currencies. The CFTC has been investigating suggestions that the banks deliberately moved the rate in order to profit on these deals.
