Soft fork, though a bit aggressive, as it would invalidate all existing blocks above the first new halving height block which claimed more than the reduced reward.
Increasing the value would be a hard fork, as it would validate blocks that would previously have been invalid, as opposed to a soft fork, which invalidates blocks that would previously have been valid.
