PB is prime brokerage

CS is Credit Suisse, and FX is foreign currency trading.

Apologies, PB is prime broking. It's where the bank offers trade facilitation services, especially lending, to a hedge fund or family office.

Just a general suggestion for comments: if you’re going to use abbreviations, it’s probably a good idea to spell them out on the first mention.

PB is probably prime brokerage, it is a managed service offered by large institutions to other large institutions.
