Financial was not the reason for your refusal it was definately your relevancy of course that you choosed and your previous application. I guess, Ielts score be the another factor of your refusal.
I think you will have to reapply after getting caips note because in that you can able to know what was in VO mind to rejecting your application and then when you will lodge your file with strong sop stating reason that you are deserving candidate.
