A PhD can help with jobs that don't really require a PhD, especially in finance. I have a few friends who ended up joining large investment banks after their DPhils at a higher level than those who had joined straight after their bachelors as analysts and worked up. This is in the UK though, where PhDs can be 3 years and completed immediately after a bachelors, so they were entering the job market at 24/25.
