Preoccupation with inflation was natural enough, after the steep rise of 1989 and the months immediately preceding the change of government. The monthly rate of inflation ranged between 25 percent and 32 percent in the second half of 1989, exceeded 40 percent in June 1990, and amounted to 78 percent by July.

The new government had to act quickly, and did.
