What could be the suitable thesis topics in banking (related to finance) sector?
Not my thesis, but I would write about how the laws have contributed to the nightmare that now exists in this country with credit card companies charging as much as 33% interest, and how now even if you are late on you telephone bill that they can increase your interest rate. Most of the information that you need for this is available on the internet and from the banking commission. Maybe you better not sound like a knight in shinning armor, your professor might not like what you have written, but look for yourself the credit card companies have done this in the name of greed, but the over all cost is not just to their card users but to everyone that use American dollars.
