An intra-corporate case was filed before RTC. On the other hand, another complaint was filed before BSP to compel a bank to disclose its stockholdings invoking the supervisory power of the latter. Is there a forum shopping?

None. The two proceedings are of different nature praying for different relief. The complaint filed with the BSP was an invocation of its supervisory powers over banking operations which does not amount to a judicial proceeding. (Suan v. Monetary Board, A.C. No. 6377, Mar. 12, 2007)
