Question

What bank does ExxonMobil use for their investments?

Answer 1

Their Form 4/2008  Document 10-F states that they use JP MorganChase. Seems like Ranto is doing some guessing here.

Answer 2

I suspect that their treasury department is large enough where they do their own trading.  The probably use one of the big I-Banks for clearing their trades -- but it is likely they do everything else themselves.
