Crony capitalism describes any situation where success in business depends on close relationships between business people and government officials.
Over the last decade, top financial firms have succeeded due to central bank policies that the firms themselves have been part of shaping. For example estimates are that "too big to fail" banks make an extra $34 billion per year off of the implicit guarantee from the federal government.
Moving on, McKinsey studied the effects of the US government policy of quantitative easing. See http://www.mckinsey.com/insights/economic_studies/qe_and_ult... for the full study. The bottom line is that it is estimated to have directly enriched private companies to the tune of $460 billion dollars (about a third of which went to banks), and cost American households $360 billion. That's a pretty large and direct transfer of wealth!
This study examines how much room Europe has to pursue similar policies. JP Morgan is effectively telling the central banks, "Here is how much money we think you could afford to give us." But doing so in a sufficiently opaque way that it isn't obvious that that is what they said.
Even assuming any of that is credible, here were not talking about a personal relationship with government. We're talking about public projections and studies that at best influence government through persuasion not relationships.
