How can a multifamily office coordinate with several private banks without duplicating work?
Use one operating model for every bank. Set a central data owner, a shared investment policy, clear responsibilities, and a fixed reporting calendar. Request standardized data from each bank, reconcile positions centrally, document decisions once, and distribute approved instructions through controlled channels.
Set one source of truth
Create a central register of every account, mandate, custodian, currency, liquidity need, and relationship contact. The multifamily office should own this register. Each private bank should provide updates in an agreed format and schedule. This reduces repeated work when preparing reviews.
Use a written investment policy statement for the family. It should cover risk tolerance, return goals, time horizon, liquidity needs, tax considerations, and legal restrictions. The policy gives each bank the same operating framework.
Divide responsibilities in writing
Give each bank a defined role. One may handle custody and cash management. Another may provide lending. A third may manage a specific portfolio sleeve. Record who can recommend, approve, execute, reconcile, and report each activity. Require written confirmation before responsibilities change.
Keep advice and execution records together. Ask each adviser and bank to disclose compensation, related-party relationships, and product conflicts in writing. The office can then compare proposals using the same checklist and maintain a clear record of decisions.
It is important to decide early on what you do not want to do, what you are not good at, what you do not enjoy, and what you will for sure not be investing in or needing so you can ignore or politely say no to 95% of those that are asking you for your time.
Standardize reporting and approvals
Set one monthly data deadline and one quarterly review meeting. Request positions, transactions, cash, fees, credit balances, performance, and outstanding actions in consistent files. Reconcile the files to independent statements before circulation.
Use an approval matrix for wires, trades, private investments, and credit changes. Store the final decision, supporting analysis, and approval once in the office record. Send each bank only the instructions it needs. Review the workflow after any new account, mandate, or family change.
