Mitsubishi UFJ: The recent rise in the New Taiwan Dollar can be considered a "19 standard deviation event".

Mitsubishi UFJ Financial Group describes the recent surge of the New Taiwan Dollar as a "19 standard deviation event." For those familiar with statistics, a "19 standard deviation event" means something that is almost impossible to happen. The surprising result is that it actually happened. The New Taiwan Dollar recorded its largest daily increase since 1983 on May 2, possibly even reaching a historical high, with a total appreciation of 5.5% for the week.
