Why did finland expect that to work when >90% of money was in banks? When the article described cutting money in half, my very first thought was wondering what the banks did -- were the bills there also cut on half or were all accounts artificially divided in half? It didn't cross my mind that all money other than physical cash was completely unaffected.

Now clearly I'm not smarter than the top economists in a country of millions, so what am I missing? Why did they think it would work?
