In the course of the first quarter 2001, however, it became clear that price pressures were beginning to subside. This was due to the economic downturn in Switzerland and abroad as well as the faster-than-expected decline in oil prices. On 22 March, the National Bank reacted to this development by lowering the target range for the three-month Libor rate by 0.25 percentage points to 2.75%–3.75%. This was the first adjustment of the target range since mid-2000.
