Common Tater, I still don’t understand what you’re getting at. You CAN’T get interest on gold, any more than you can get interest on Federal Reserve Notes. You stuff gold or dollar bills into a vault and you get no interest from it.
The only possible way you can get interest is by LENDING money. You have an amount of money, and since money today is worth more than money tomorrow, you lend it to an entity, it could be a person, it could be a bank, it could be a corporation, it could be a government. They agree to pay you more money in the future than they borrowed today. But they won’t pay you extra money if they have to stick that gold or banknote under the mattress. They won’t borrow the money unless they have a plan to use that money today to create goods and services that will be worth more money tomorrow.
If I take a gold coin and ask the goldsmith to keep it in his vault for me, does he pay me interest for the privilege of keeping my gold coin? Why would he? What’s in it for him? But he might pay me interest if he can take that gold coin and use it to purchase raw materials that he can convert into finished products and sell those products for more than the cost of the raw materials. Or perhaps the goldsmith won’t produce those products, but rather loan the gold coin to someone else who will, who’ll pay HIM interest, which will be higher than the interest he’s paying me. But just keeping that gold in a vault doesn’t help him make any money, and therefore no interest.
And note that “gold standard” money is literally created out of thin air, just like fiat money, the only difference is that under a precious metal standard there’s one particular good that has a fixed price. Gold, or perhaps silver. But gold or silver or copper or platinum ingots aren’t money, they are goods. Why do we need one good with a fixed price?
Countries on a gold standard saw their money dribble through their fingers in mysterious ways. Spain brought back galleonloads of gold and silver, and yet somehow that “money” vanished into the hands of foreigners. Why did the money leave Spain? It’s simple, the law of supply and demand, the increase in supply of a good (in this case gold, what they thought was “money”) decreased its value. They traded their gold bullion for luxury goods and that gold and silver made its way from the Americas to Spain to the Ottoman empire and on to China and India. They thought that by increasing the amount of “money” they had, they increased the wealth of their country. Except that doesn’t work any more than running the printing presses to create more fiat banknotes.
And a piece of paper entitling you to get a certain weight of gold is not any “harder” than a grocery store coupon entitling you to 50% off a frozen pizza. Fiat money is exactly equivalent to a coupon issued by the government…not for a lump of gold, but for payment of your taxes. And if the government’s word that it will accept that coupon for payment of taxes isn’t good enough, why would their word that they will exchange that coupon for a pretty rock good?
And note how the fiat currencies of first world countries are called “hard currencies”, in contrast to the worthless government coupons of third world dictatorships and communist hellholes. No international bank or corporation will take North Korean banknotes in exchange for goods and services, yet around the world there are companies that will eagerly take US dollars, Canadian dollars, Yen, Euros, and British Pounds. All backed by nothing more than a government’s assurance that yes, these electronic signals are exchangable for pieces of paper that other people will exchange goods and services for. A fixed price for one particular good (gold bullion) adds nothing to the value of that electronic money.
