Five years ago you could trade 69 rubles for 1 dollar. Today it takes you 96 rubles to buy 1 dollar. That is a decline of 38% in purchasing power between the currencies.
ALL of the BRICS national currencies have declined in purchasing power against the US dollar over the last five years. Some more than others, but none have appreciated.
Do you understand what "decline" means in this context now?
“Do you understand what “decline” means in this context now?”
You still did not define “declined”. You defined exchange rates.
But the prices of goods and services didn’t change by that much in Russia. And they are much more competitive on global markets now.
The same is true for the other BRICS nations.
That is probably the reason why the US has the record breaking trade deficit with China, and the US banks have $1.8 trillion in unrealized debt vs $2.2 trillion in liquidity.
