Only two years later, on September 5, 1987, the government demonetized the 25-, 35-, and 75-kyat notes without warning or compensation, rendering some 75% of the country's currency worthless. The resulting economic disturbances led to serious riots (see 8888 Uprising) and eventually a coup d'état in 1988 by General Saw Maung. On September 22, 1987, banknotes for 45 and 90 kyat were introduced, both of which incorporated Ne Win's favorite number, nine.
