There were reports of public outrage and confusion after the announcement of the measure, which requires North Koreans to swap existing won notes for new ones at an exchange rate of one to 100 — effectively knocking two zeroes off their value. Because of a cap of 100,000 won per family (£475 at the official exchange rate), anyone with significant holdings of cash will have their savings wiped out.
The move is seen as an effort to quash small businesses and private enterprises which have proliferated in the unofficial economy. As many as 30,000 vendors are believed to operate in a market outside the capital, Pyongyang, and many of them had accumulated substantial cash reserves. This move effectively confiscates that cash.
Analysts do not foresee any direct economic repercussions outside the country, but it does serve as a reminder that many other world currencies are, like the North Korean won, "fiat money"

The difficulty is in the cap. If you were told that you could only convert £1000 of savings into the new units and had to abandon the rest I reckon you'd be a bit miffed, too.
You would be basically right, except for the caveat "cap of 100,000 won per family (£475 at the official exchange rate)."
In other words, anyone who has more than £475 worth of cash (in N Korean currency) will lose 99% of the value of that extra cash. Instantly. If they jad held their wealth in goods or foreign currency, they'd be fine. Unfortunately now that this has been announced, it is too late to do that. I'm sure if we could see the finances of some government officials, we'd find at least a few trades on currency and commodity markets in the recent past, though.
I think that only 5% of the population of North Korea at most is even capable of investing outside of their country. Little gets in, and little gets out. Anyone living there that is trying to leave the country without government permission is shot, but if they manage to get out they are considered treasonous, and their family is sent to a concentration camp. These people are screwed.
