This snapshot of the Russian Ruble (you see it spelled "Rouble" sometimes) value relative to the US dollar is from today's Bloomberg website:
Right now, the institutional market price (different (lower) than the market price we would pay) is $1.00US will exchange for 65.7746 Russian Rubles.
One year ago (look in red circled area) $1.00US exchanged for 32.4834 Rubles.
This means the US dollar can exchange for approx 33 more Rubles than it did one year ago. The dollar "buys" more Rubles than it did before, hence we can say the US dollar has APPRECIATED relative to the Ruble by about 102% (rounded).
Exchange rates are reciprocal to each other. If $1.00US exchanges for 65.7746 Rubles then 1.00 Ruble will exchange for 1.5 US cents
One year ago, Russians could exchange a Ruble and get 3.1 US cents. The Ruble "buys" fewer cents than it did before, hence we can say the Ruble has DEPRCIATED relative to the Dollar by 51% (rounded).
This has major consequences for US businesses that do business in Russia and want to expatriate profits or investments back into US dollars.
Simple example. A year ago, a business that earned 1,000 Rubles in profits could exchange those Rubles and receive $30.78US (1,000 Rubles/32.4834 Rubles per Dollar).
Today 1,000 Rubles would exchange for $15.20US (1,000Rubles/65.7745 Rubles per dollar).
Exchange rates matter because they can change the relative value of goods and services across borders WITHOUT changing the properties of those goods and services.
While writing this post, I checked the BBC and coincidently they have this story:
