At your age, an executive MBA would likely be your best route. It's only one year.
Unless you're getting into a top 15 schools (which given your age, is unlikely since they prefer people in their late 20s/early 30s), getting an MBA is typically not a worthwhile endeavor. The price tag and time away from work are too big of an opportunity cost.
If you want to do something financial related, you could try getting an CFA. It's considered a 'self-study' MBA and has quite a bit of credibility, at least in the U.S. You need to pass three exams to earn a CFA and each exam, along with the study materials, costs around $1300.
