What's the Difference: Repo/Sec Lending, at Money Market Desk vs in Prime Brokerage

Hi all,

Hope you had a great long weekend!

Really interested in repo/Securities Lending. Could you guys introduce more details?

especially, traditional repo/Sec Lending usually is a part of Money Market Trading Desk, or as a part of Treasury, funding the bank's trading desks as well as the balance sheet.

But, I also know there is a Repo/Sec Lending function in BB's Prime Brokerage Business.

So: is there any difference between the above two?
is Repo Trader in PB much more Profit-oriented? Do they also have the duty to provide funding?

In short, are they two the same type of Repo Traders? or, they are just very different?

I really want to get a clear idea about the different roles of Repo/Sec Lending...

Any insights will be really helpful because it is so hard to find the introductory resources online...

Many thanks!!
