Navigating relationships with HQ team at a regional office — how to build those connections without being annoying?

Started my first week as an analyst at the Andean region office of one of Latin America’s largest regional banks (think Itaú BBA, BTG Pactual tier). The bank has a significant global footprint with offices across LatAm, Europe, and beyond — which was a big part of why I chose this over other options. The access to a truly regional and international platform was the draw.

Here’s my situation: the local office where I sit handles origination, client relationships, and deal execution locally. But the heavy lifting in terms of deal flow, models, financial materials, and balance sheet capacity largely originates from and is led by the mothership — a much larger hub with significantly more resources, senior talent, and deal experience.

I do have access to the mothership team — their emails, org charts, and I’ll be on calls with them. But I’m two days in and haven’t built any relationship with them yet. The analysts here have told me it’s not always easy to get meaningful time from the mothership team beyond the transactional — they’re busy, they’re senior, and a junior analyst in a smaller regional office isn’t always top of mind for them.

My question is: how do you navigate this dynamic effectively?

Do you just ask ask ask without fear whenever you need something? Or does that come across as annoying and damage the relationship before it starts? How do you build genuine rapport with bankers at HQ who are more experienced and have more resources when you’re just starting out and geographically removed?

I want to make the most of the access this platform gives me — both for learning and for building relationships that are useful long term. But I also don’t want to be the regional analyst who pesters the mothership team with basic questions they find annoying.

Any advice from people who’ve navigated similar hub and spoke dynamics at large banks would be really appreciated.
