On Monday morning, Americans woke up to find that their dollar could buy more in Russia than ever before, with a single dollar able to buy 60.46 rubles.
The biggest cause of that shift? The corresponding collapse in oil prices over the last few months.
Since June, the price of crude oil has gone from around $115 per barrel to less than $60 USD as of Monday morning.
Making matters more unpredictable, oil's main cartel — OPEC — isn't about to step in anytime soon. As recently as Sunday, OPEC Secretary-General Abdallah Salem el-Badri said members would not shore up oil's prices by cutting supply.
Because OPEC produces around 40% of the world's oil supply, that decision to leave things as they are carries a lot of weight.
Right now, OPEC countries have a combined target set to produce 30 million barrels of oil per day. At the group's last meeting in late November, they decided to keep to that target, even as prices continued to fall. In fact, they wound up collectively pumping almost a half a million barrels above the target last month, Bloomberg News believes.
Here's the thing: A lot of countries that mainly export oil tie their budget to its market price, needing it to be a certain cost to break even. As this chart shows, at less than $60/barrel, a lot of these countries are in for a world of fiscal pain.
Such a low price has produced scary looking charts like this one, which shows how the Russian ruble plunged in value this year.
Alex Kliment, an analyst at the Eurasia Group, explained to BuzzFeed News via email just why Russia was letting the ruble drop so much. It's complicated, but the short version is that countries that don't fix their exchange rate — like Russia — can let their currency's value slide around. In this situation that makes sense because while oil is sold in dollars, the Russian budget is kept in rubles, so dropping the value of the ruble against the dollar lets Moscow keep the budget all nice and orderly.
So while the budget will remain technically "balanced" this year, Kliment said, the slide will likely cause "higher inflation because foreign goods become more expensive and Russians rely on foreign imports for a lot of food and consumer goods; as well as increased debt burden on companies that have dollar-denominated debt; capital flight." Then there's the matter of next year's budget, which is a whole other thing.
