M.S

Hi Saurav,
A Master's degree in Finance or a related field is recommended but not necessary. You can also have an MBA and then opt for PhD in Finance. You must however demonstrate excellent knowledge and quantitative skills, relevant experience and interest in Finance and high level inclination towards research and academics and the given subject. Assuming from your question that you are looking for a Ph.D in USA, please note that you must give the GMAT and TOEFL as a part of the admissions process. Having a FRM will definitely add a value.
Some of the best B-schools you can consider are:
1. NYU Stern.
2. University of Michigan.
3. Eli Broad College of Business.
4. University of Chicago – Booth.
5. University of Illinois at Urbana-Champaign and
6. University of Virginia Darden School of Business.
These are some of the CFA Partner Universities and amongst the most competitive schools.
I would also request @|John64176| to put forward his valuable suggestions here. Hope this helps.
