I hope that the economy rebalance won't increase global gold supplies. Gold is plentiful enough -- what with so many families reaching the wealth cap so soon after it was raised -- it would unbalance things further if gold supplies were increased.
As I believe has already been stated, the current version of the rebalance would increase gold supplies by around 10% on every continent.
Part of the reason for this is simply that if it did not provide a net increase, there would be much wailing and gnashing of teeth, and many people would feel, that, no matter its long-term effects, it was a terrible, awful change just because it reduced the gold in their favourite areas.
