The British Bankers’ Association (BBA) publishes the LIBOR everyday while Thomson Reuter calculates it. This official interest rate is an average of the inter-bank deposit rates of designated contributor banks for maturities that range from overnight to a year. LIBOR rates are benchmark rates rather than tradable rates. The actual rate, however, varies throughout the day.
The sterling three-month LIBOR rate affects the rates lenders establish on loans to consumers and businesses. This rate also affects the amount they lend. Since the LIBOR rate is linked to a lender’s costs, mortgage deals are increasingly linked to LIBOR rates rather than bank rates. The countries that rely on LIBOR rates as reference include Canada, the US, Switzerland and the UK.
The Eurodollar of Chicago Mercantile Exchange contracts rely on three-month US dollar LIBOR rates. These contracts extend up to ten years and they are the most heavily-traded short term interest rate futures contracts in the world. Shorter maturities are traded on the Singapore exchange in Asian time.
LIBOR mortgages are adjustable rate mortgages on which interest rates are based on a specified LIBOR index. Once the rate is fixed during the initial period, it is adjusted to be equal to the most recent value of the official interest rate or the LIBOR index. Then the margin is added subject to adjustment caps, if any.
LIBOR adjustable rate mortgages are developed to meet the requirements of foreign investors who are looking to reduce risks associated with dollar-dominated investments. A foreign bank that purchases the six-month official interest rate or LIBOR adjustable rate mortgages can borrow required funds in the inter-bank market for six months.
