The 95% devaluation doesn't really change anything - unless you were specially connected, you couldn't change bolivars for USD at the official exchange rate. At most this devaluation just brings the official rate back in line with the black market rate, which is the real exchange rate because that's the only rate at which you can actually exchange currency.

Folks holding bolivars (and creditors, and pensioners) were already screwed. This just makes it official.
