It might be suitable if you are aiming for a career that will let you transition between business analyst roles in IT consulting and those in industry (IT departments), if you have not established your career yet, and you do not want to commit to IT consulting vs. industry. There are a couple of caveats there, so let me explain.
Career stage: work experience in business analysis and project management counts for a lot more than any certification. Once you have established your ability to do the job (with a similar organisation, industry, technology solution, etc.) then certification does not add anything to your resume.
IT consulting vs. industry career: BABOK would not be appropriate if you intend to stay in IT consulting for some years as the firm will have its own preferred "qualification" process, which may be certification-based or on-the-job. Either way, they will want to train you in their methodologies (so external certifications can even count against you) and they will pay for their preferred training (so external certification can be a waste of money).
There are two other assumptions that I've made which may caveats if you've not already made them too.
Location: check that the certification has a strong reputation in your desired location; I presume you're in the U.S. where IIBA markets BABOK. In the UK and mainland Europe, I would doubt any hiring manager will recognise the certification and certainly none will be actively interested in it.
Profession: I know this forum is shared between IT and management consultants; this certification is only going to be relevant to the IT profession. "Business Analyst" is a different role in management consulting, requiring some similar but many different skills and abilities.
