The flipside of this is thinking about strategic positioning of the banks themselves. If an investment firm has access to a thruster capable of relativistic time dilation, then the loaning arm of the entity has incentive to be moving as fast as it can, while charging market interest rates: The bank experiences less time, and therefore multiplied returns on interest. I can certianly see there being a case for some sort of aristocracy or 'first world' which lives in dilated time, and therefore benefits from the dilation. Of course, they sacrifice reaction time to do so..
