Manoj,
First of, I'm assuming when you mean "Banking" you're talking about Invesment Banking, since Investment Banking is related to the Stock Market which, in common jargon, is called Sales & Trading. So I'll be focussing on Investment Banking and Sales & Trading.
If you want a career in Investment Banking & Sales & Trading at a leading Investment Bank, the only way you'd be able to break-in, is by getting an MBA from a leading business school, like IIM/XLRI/ISB.
A CFA isn't really a sought after qualification in many Investment Banks. A CA should generally suffice for the knowledge part, as is evident, after having a look at the profiles of leading Investment Bankers in India.
If you take a look at indigenous I-Banks like Avendus Capital, Veda Capital, etc., you'll see that most of the individuals comprising the Executive Team/Lead Team have a Chartered Accountant's designation with/without an MBA from a leading business school.
The question is, those with just a CA take a whole-lot more time to break into I-Banking, and it depends more on luck. If CA's are lucky enough to land a role at an I-Bank and they get promoted into a position of I-Banking, they'd be able to make a career in it.
If you choose to follow a fast-track route into I-Banking, your only savior will be an MBA.
My Final Attempt is due in November 2014 as well. I'd love to get into I-Banking/ Sales & Trading as well. The only way I think it'll be possible for me is to get hired on the Campus for a Financial Services firm like JM Financials, Credit-Suisse, Deutsche Bank. Work in the back-office for a while, say 2-3 years, prepare for CAT and get into a top notch Business School. After having completed MBA, go back to your old Company and apply for a front-office I-Banking role there, or sit for Campus and test your luck in getting hired by an I-Bank. Either way, it's a lot more simpler to find a way into I-Banking after having completed your MBA.
With just a CA, you could only make a career in I-Banking/.Sales & Trading if you have a strong network of relatives already working in one of the leading Companies or by sheer luck.
Anyways.
I hope you found this information useful.
Cheers
Sam
