As broad-based sanctions cripple the Russian economy, the West is also ratcheting up economic pressure targeted at the country's oligarchs — known for their splashy yachts, big-name investments and piles of dark money squirreled away around the globe.

The U.S. and Europe are hoping that if they squeeze the oligarchs, the oligarchs may pressure Putin. In the longer term, going after hidden Russian wealth could curtail the power of Putin and his circle.
