This is a question that I sort of view as an intersection between economics/science/space, completely hypothetical in nature, so I'm not sure if this is the right forum for it but, here goes:
I read an article with the headline 'Asteroid passing close to Earth could contain $5.4 trillion of precious metals'. I've seen similar articles talking about the value of metals in asteroids in the past.
My question is, suppose one of these asteroids, on a smaller scale, landed somewhere in the desert, and contained hundreds of billions of dollars worth of precious metals. What would something like that do to the economy? Obviously our money is worth what it is because of the amount of it that is in circulation to some degree, so, if all of a sudden there was an infusion of billions of dollars into the economy (albeit over time), would it have a detrimental impact on the economy? I'm not an economist by any stretch, but in just thinking about it, I've wondered what the effect would be on the economy if suddenly there was hundreds of billions more in precious metals that landed here, not just passing by in space. Would the major impact simply be that the value of those metals would rapidly decrease, or would there be a larger impact on the global economy? Maybe the answer is nobody knows, but theoretically, I've tossed this around in my mind.
This may be a question more suited for an economics forum, and I'll be happy to move it there if so.
