Putin may want to rethink his sandbox strategy. Russian oil firm Rosneft has asked Moscow for $42 billion as international sanctions begin to sink in. The U.S. has banned long-term loans to Russian firms, leaving them scrambling to replace foreign finance. The state-run oil producer probably won’t get the money and is due for a $12 billion debt repayment later this year. But unless Putin learns to play nice, it’ll be the first of many such pleas to reach his desk.
