The Basel III decision meant that gold as a reserve of the third category was earlier estimated at 50% of its value on the balance sheets of world banks.
And now it was decided to place gold not in the third, but “just” in the first category. And it means that now it is possible to evaluate it not at 50, but at 100% of its value. This leads to the revaluation of the balance sheet total.
