LIBOR - The London Interbank Offered Rate

The London Interbank Offered Rate, also known as the LIBOR for short, is a daily reference rate at which banks offer to lend unsecured funds to other banks - specifically on London's money market. The LIBOR, however, is used all over the world as the basis for many securities that return a variable rate of return. Why is all this important or interesting? Well, the way it is calculated has come under attack in recent years and that model may very well be changing as a result.

The non-governmental British Bankers Association (BBA) that sets the LIBOR does so by first collecting reports from its member banks. These banks report what their costs of borrowing are to the association which are then figured into an average for use by all banks as their reference rate - the basis on which they offer funds to business and individuals for anything from mortgages to company lines of credit. In recent years, however, there has been mounting speculation that the member banks reporting their borrowing costs have been fibbing - under-reporting so as to keep their own borrowing costs lower.

With the slowing world economy and continued concerns over credit availability for many financial institutions - not exclusively those in the United States - interest rates are expected to begin to rise. Just as this means our own cost of borrowing on car and school loans will begin to tick upward, the big banks are concerned that their own costs will rise. Having issued much of their recent loans at the presiding low rates and many still saddled with quickly depreciating assets, this does not paint a rosy picture for banks as an industry. Of course, it's hard to see how this is any justification for manipulating the system for their own benefit.

As with CDOs, default swaps and mortgage-back securities, it's important for any investor to understand exactly what it is that they're buying when they invest their savings. The LIBOR is one of those elements that many of us likely take for granted, but this too should be a factor in our investment decisions. Understanding that the LIBOR is a manufactured entity should spur our own questioning of its validity and interest in alternatives - and there are many. The Fed Funds Rate, the Treasury Bills rate (for the relevant maturity, of course) or even your own banks prime rate. Consider the alternatives; talk with your bank managers and choose a reference rate with which you feel comfortable will provide you with an accurate representation of the cost paid by banks - the cost that they will the pass along to you.
