Nobel laureate in Economics: Russian trade surplus is a sign of weakness, not strength
As usual Paul Krugman explains Economics in a simple, easy to understand way: Russia is exporting much more than it's importing, not because they are selling lots of oil, but because they can't import anything, due to sanctions
The article is three days old, but in case you haven't seen it:
So is Vladimir Putin winning the economic war?
No, hes losing it. That surging surplus is a sign of weakness, not strength it largely reflects a plunge in Russias imports, which even state-backed analysts say is hobbling its economy. Russia is, in effect, making a lot of money selling oil and gas, but finding it hard to use that money to buy the things it needs, reportedly including crucial components used in the production of tanks and other military equipment.
Why is Russia apparently having so much trouble buying stuff? Part of the answer is that many of the worlds democracies have banned sales to Russia of a variety of goods weapons, of course, but also industrial components that can, directly or indirectly, be used to produce weapons.
