Apple Inc. has suspended sales in Russia due to wild fluctuations in the value of the ruble, as the impact of declining world oil prices and Western sanctions continue to destabilize the currency.

The Russian ruble dropped 19 percent in market trading Tuesday, dropping to a low of 80 rubles to the dollar. In late trading the ruble was back up to 58 rubles to the dollar as the Russian Government increased interest rates from 10.5 percent to 17 percent.

An Apple spokesman told Bloomberg that “Our online store in Russia is currently unavailable while we review pricing.” The spokesman did not say when the store would return.

Apple’s international stores regularly review prices relative to exchange rates, but this is the first time the tech giant has suspended trading.

On the ground, reports suggest that there is a full-blown panic, and that “fear has taken over…with a run on the entire country.” Russians consumers are said to be swamping “malls to swap cash for washing machines, TVs, or laptops—anything that might hold value better than paper money.”

Apple does not have a bricks and mortar retail presence in Russia outside of third party retailers, and sells a modest 1.3 million iPhones a year in the country from a worldwide total of 153.4 million.
