I've been noticing that since Russian ruble started losing its value compared to other foreign currency, at some point it became at constant exchange rate of 1 RUB to 0.01 USD.
That is, every day no matter how much value the ruble keeps losing, at the beginning of a new trading day it bumps back to 0.01 USD:
This puts the ruble at an overall fixed value, since its previous day value is the same as new trading day's value:
I assume Russia's central bank is taking measures to stabilize their currency's value, but is there a reason for this specific value? And how is it possible to achieve a fixed exchange rate? Buying your own county's currency with your own foreign currency reserves?
