To be absolutely candid, I don't fully understand this issue after perusing a number of articles (like this and this) related to the subject. However, it certainly appears that the banking industry, which are worried about their loans to the oil fracking industry and their derivative bets, has sought, and apparently succeeded, in protecting themselves from losses (by dumping them on taxpayers) from the Empire's oil dumping strategy to destabilize the Russian economy.
This seems like a hugely risky ploy because another bailout would likely trigger major threats to the capitalist class. But then, it seems like all the other actions that the directors of the Empire have taken in the past several years have seemed desperate to me. Nevertheless, I urge you to use your own judgement, as always.
After last minute, heavy lobbying on the budget bill by Jamie Dimon of JPMorgan Chase and an army of 3,000 Wall Street lobbyists, it appears that once again sufficient insecurity and fear had been spread among the political class regarding destabilization of the financial markets (or withdrawal of campaign financing). They allowed a last minute amendment that killed Dodd-Frank protections, and allowed US taxpayers to be shaken down to cover Wall Street's shale gambling debacle.
