What if in the future space mining become true, think about Federal Reserve Bank of New York, all funds that are stored in gold and other metals are now priceless (if prices of gold and other metals drops). How would that affect the global economy?

Some data.

* The US Government has a gold reserve of about 11 billion USD.

* The US GDP is about 19 trillion USD per year, or 52 billion USD per day.

* The US federal government revenue is about 3.6 trillion USD per year, or 9.9 billion USD per day.

So the US government has a gold reserve that is about:

* 5 hours worth of GDP. 

* 21 hours worth of federal revenue.

Even if all the gold vanished overnight, it would be little more than a footnote in the US government budget. If we had a technology that made it inexpensive to mine gold and bring it back to Earth*, whatever that imaginary technology might be would have an effect on the global economy many orders of magnitude greater than the value of the now worthless and abundant gold.
