LIBOR and the seeds of the recession
October 6, 2008
The British Bankers’ association’s London Interbank Offered Rate (LIBOR), the rate at which banks loan money to each other, is a good indication of how risky is the world is seen to leading banks. In the case of the US dollar rate, there sixteen banks on the panel that determines the LIBOR (see here for a great description of how LIBOR is determined)
The LIBOR is the beating heart of the interbank system, and reacts instantly to new information. However, it also shows how risk perceptions, and following these, a potential recession, come about.
The LIBOR rates for the first 29 days of September show this vividly. The line marked O/N (you can disregard the S/N as the graph is for USD) is the overnight rate at which banks are ready to loan money to each other – the shortest period of loan. The jump on 16th of September to the 18th indicates the flight to look at the jittery. The longer periods follow suit (1 week, 2 week, etc), as can be seen, but more moderately. The jump is dramatic, of course, but more ominous is the longer-term change that the graph reveals. First, LIBOR rates have moved up from about 2.5% to almost 4%. This indicates the higher degree of risk assigned to loans. This on its own is important, but even more telling is the spread of rates across the different periods. While on 1st of September, the range between the lowest and the highest rate was 0.8%, (not taking into account the very volatile overnight rate), the range on 29th of September is only 0.09%! This shows that not only that banks see their environment as riskier than before, but they also distinguish less between more and less risky loans. In fact, they tend to see all loans, regardless of the period for which they were taken, as risky. Such, diminished distinction is a sure sign of flight to liquidity – institutional risk avoidance, but it is also a reflection, if it continues, of a slowdown in macroeconomic activity. If all loans are seen as high risk, less loans are going to be granted.
