In terms of gold, if 1000 more tonnes of gold is discovered and as soon as people find it out, they double their prices and salaries. They don't wait till they start earning double to spend double.
So that laptop I wanted to buy is immediately now for 2KGs of gold. It doesn't matter whether I have that gold or not. I would simply wait till my salary reflects the extra gold in the market and then I go and buy the comp.

I gave example of laptop there, which may again raise some questions because laptop is not a commodity which is sought desperately everyday.

Let's say, if I need one Kilogram of wheat flour or Rice to make food, I wont wait for my salary increase, I can't, I have to eat everyday until salaries are increased....?

So, what will happen for the daily usage commodities in times of such influx of extra gold?

Remember one thing, whenever there is a problem like this, this is a demand in the market to find a solution for this. And anyone who finds a solution to this problem/demand makes profit.

Basically you check the gold prices every day. If gold prices go up, you automatically get paid less salary, if gold prices go down, you are automatically paid more salary, at the same time, everything you buy has a higher price. The market will form a mechanism for this thing.
