Lol. The ruble is sliding because it’s a shit currency and was propped up by the Russian central bank buying rubles with their reserves of euros and dollars. In Russia right now there is a limit on domestic exchanges of rubles for dollars and dollars collected by businesses must be turned over to the government for rubles because they need them so bad. Now that they are running out of euros and dollars the ruble is sliding because the Russian central bank is holding yuan and the demand for yuan is weak so their ability to buy rubles has weakened, hence the slide. Which will continue unless they start unloading gold. Which they will have to. Which is why I would be bearish on gold right now.
You are the one that thinks all currency is the same and can be exchanged with ease. It cannot.
And please if you don’t understand something it doesn’t make me stupid. There’s nothing wrong with learning. I assure the way you understand currency reserves of central banks is completely wrong. Central banks maintain currency reserves to ensure the stability of their domestic currencies. It’s not a swap 1:1 or like collateral. Central banks are continuously moving large amounts of currency and metals to control their own currencies. It’s why even with all of the debt america has there still isn’t enough dollars in the world for central banks. It’s because foreign currencies need more and more to stabilize their own currencies.
And the yuan certainly does not spend like a US dollar. You can spend a US dollar almost anywhere in the world and for almost anything in the world. To spend a yuan in most markets means you will have to exchange it for the local currency, dollars or euros which will incur a cost or fee, weakening your ability to buy with it. And the rupee is even worse. Many exchanges won’t even exchange a rupee without huge fees. It’s a terrible currency and why the trilateral exchange of rupees, rubles, yuan completely failed a few months back.
The Indians will gladly unload rupees for oil to the Russians. It’s an awesome trade for them.
