Going Independent With an International Book: The Custody Myth Keeping Global Advisors Captive

Advisors with international clients stay at global brokerages out of pride in the brand on the statement. The record shows the opposite story: for a decade, the big brands have raised minimums, dropped countries, and closed international accounts by the thousands, while the custodians serving independent advisors built platforms for exactly those clients. The vault was never the brand.

Can an Independent Advisor Serve International Clients? The Custody Reality

The short answer: Nothing about an international book requires a global brokerage. A US-based, US-licensed advisor serving non-US-resident clients can run that practice independently, with the assets custodied at the same class of institution that already clears for the industry, subject to each custodian's country list. The pride that keeps international advisors at the big brands, "my clients' assets sit at a global name," has the last decade exactly backwards: the global names spent it raising international minimums, dropping countries, and closing accounts by the thousands, while the custodians behind independent advisors built out international platforms to catch what the brands let go.

We hear the same two objections from legacy advisors at the global firms. Going independent is somehow beneath a serious international practice. And international clients need the big brand's vault. The first is folklore. The second is factually upside down, and the record is long enough now to prove it.

What did the global brands actually do to international books?

Not rumor, not tone. Dated, reported policy, firm by firm.

Merrill Lynch, 2015 to 2016. Merrill eliminated service to more than 50 countries outright, designated others limited-coverage, set a $2.5 million minimum for new international clients and a $1 million minimum for existing ones ($5 million for Canada), and required international clients to visit the United States in person during 2016 or be terminated. Advisors who had built cross-border practices sued over what the changes did to their client relationships; the firm denied the allegations. Either way, the policy stood.

Morgan Stanley, 2015 to 2024, in escalating rounds. In 2015 the firm restricted international business to roughly 400 authorized advisors with a $500,000 account minimum, routing smaller clients to a call center, having already sold its onshore wealth operations across seven countries. In February 2018 it told some overseas clients to liquidate or transfer within 30 days. In April 2019 a $2 million international minimum took effect. In November 2022 it closed thousands of accounts and raised international minimums again under an enhanced due-diligence review. In July 2023 it raised minimums fivefold in riskier Latin American markets, and trade coverage described advisor exits reaching a breaking point. By November 2023 the closures were so broad the firm suspended them after client complaints reached the SEC, and Bloomberg reported minimums in Panama and Bolivia rising to $10 million from $2 million for mid-2024.

UBS, 2020 to 2024. In August 2020, UBS severed relationships with Venezuelan-linked clients served from US offices, an estimated $2 billion to $3 billion book, and at least 17 US-based advisors with Venezuelan clients left the firm within months. In May 2024, the LatAm wealth unit absorbed layoffs in the post-Credit Suisse restructuring.

Wells Fargo, 2021, the clean sweep. In January 2021 the firm announced it would stop serving clients residing outside the United States entirely, effective within two weeks for new accounts, with existing international relationships wound down over roughly nine months. The memo called it a decision to focus on clients who primarily reside in the US. More than 330 international advisors and roughly $40 billion in client assets went up for grabs at once.

Read the decade as one policy: every global brand concluded that small and mid-sized international relationships cost more in compliance than they return, and repriced or removed them. The brand your clients are proud of has spent ten years telling those clients, in minimums and exit letters, that their pride is not mutual.

So where do international assets sit at an independent firm?

At a custodian, which is where they were sitting all along. The mechanics are the same ones we walked through in how custody actually works: the client's account is titled to the client at a qualified custodian, the advisor holds trading and billing authority only, and the safety stack, asset segregation, SIPC, excess coverage, belongs to the custody layer, not the advice layer.

What the folklore misses is that the custodians behind independent advisors treat international wealth as a growth business, not a compliance burden to shed. BNY's Pershing crossed $90 billion in Latin American client assets on its platform back in 2019, up more than 35% in three years, with offerings built specifically for US-based firms serving Latin American investors, and by late 2023 was openly targeting new offshore RIAs and breakaway wirehouse advisors to grow the business. Schwab operates international accounts for non-US residents with no stated minimum, governed by country-by-country eligibility. Trade coverage said the quiet part out loud as early as January 2022: the wirehouse pullback from international wealth created the opening, and independent firms have been recruiting Miami's cross-border talent into it ever since.

Meanwhile the market itself kept growing. Bloomberg's 2023 reporting on Miami's rise as a Latin American wealth hub counted global banks expanding headcount and assets by double digits, in the same article that described Morgan Stanley losing clients and bankers in that market under its account restrictions. International money did not stop wanting US custody. It just stopped tolerating one firm's risk policy.

What does the compliance load really look like?

This is the honest part of the conversation, because the load is real. It is also portable, and smaller than the folklore claims.

The paperwork stack is standardized. Non-US clients certify foreign status on Form W-8BEN, which also claims any tax-treaty withholding rates on US-source income. FATCA governs institution-level reporting. Most of the world exchanges account data under the OECD's Common Reporting Standard; the United States instead exchanges under its FATCA agreements, a structural quirk that is precisely why international families want US-custodied accounts in the first place.

Country eligibility is the real gate. Every custodian, and every wirehouse, maintains a country list: which residencies it accepts, what documentation each requires, which products are available. The difference in model is who decides. At a global brokerage, one firm-wide risk policy governs your entire book, and the last decade shows how that policy moves. At an independent practice, you select custodians whose lists fit the clients you actually serve, and a multi-custodian setup can cover a book that no single institution would.

KYC is a workload, not a wall. Passports, proof of residency, source-of-wealth documentation: an advisor who has served international clients inside a wirehouse has been doing this work all along. Independence changes who profits from it.

What actually changes for the client?

Less than the taboo suggests, which is the point of the client conversation.

The client keeps institutional custody, US-market access, statements from a regulated custodian in their own name, and the custody-layer protections. The client gains an advisor whose firm cannot unilaterally reprice or exit their country, because the advisor picked the custody arrangement around them. What the client loses is a logo, the same logo that has been mailing exit letters to households like theirs since 2015.

Every dynamic we documented in what percentage of clients follow their advisor applies with extra force here: international clients are relationship-loyal by necessity, because the brand already demonstrated it was not loyal to them. And the broader economics of the move, payout, ownership, enterprise value, are the same ledger we ran in the independent-versus-global-brokerage comparison, with one addition: an international book that survived a decade of wirehouse repricing is, almost by definition, a durable one.

The taboo, priced

Here is the sentence to sit with. The belief that international assets need a global brand is a loyalty the brands themselves stopped reciprocating ten years ago, in writing, with minimums and country lists and 30-day liquidation letters. Advisors who internalized the taboo are protecting a vault that was never theirs, at firms that have been quietly shrinking the very business they are proud of.

We work with advisors who are licensed and practicing in the United States; their clients can be anywhere a custodian will accept. If that is your practice, a US-based team with a cross-border book, we will map your actual client countries against the custodians and platforms that can hold them, position by position, before you commit to anything. Request an introduction. The brands made their decision about your clients years ago. You get to make yours with better information.

Frequently asked

Can an independent advisor serve international clients?
Yes. A US-based, US-licensed advisor operating as an independent RIA can serve non-US-resident clients, with the assets held at institutional custodians that accept international accounts. Acceptance is country-by-country: each custodian maintains its own list of eligible residency countries, required documentation, and product restrictions. The practical work of going independent with an international book is matching your actual client countries against custodian eligibility before anything else, which is diligence, not a barrier.
Where does an international client's money sit if my firm is an RIA?
At a qualified custodian, exactly as with domestic clients: the account is titled to the client at an institution like Schwab, Fidelity, Pershing, or Interactive Brokers, subject to each custodian's country eligibility. The custodian executes trades, holds the assets, and sends statements directly to the client; the advisor holds only trading and billing authority. The custody protections, segregation of client assets and SIPC coverage among them, ride with the custodian, not with the brand on your business card.
Why did the big brokerages drop international clients?
Compliance economics. Serving non-US residents carries anti-money-laundering, sanctions, and cross-border regulatory load that scales per relationship, so the global firms repeatedly cut the segment down to only its largest accounts: Merrill designated more than 50 no-service countries and set multimillion-dollar minimums in the mid-2010s, Morgan Stanley gave some overseas clients 30-day liquidation notices in 2018, set a $2 million international minimum in 2019, closed thousands of accounts in a 2022 due-diligence review, and raised minimums fivefold in riskier Latin American markets in 2023. Wells Fargo exited international wealth entirely in 2021.
Is a global brand safer for international assets than an independent firm?
The safety lives in the custody structure, not the logo. At any SEC-registered arrangement, client assets sit at a regulated custodian, segregated from the firm's own balance sheet, with SIPC replacing missing assets up to $500,000 including $250,000 of cash if a custodian fails, and private excess coverage above that at major custodians. An international client of an independent advisor keeps all of that. What the global brand adds is its own risk policy, which for a decade has meant rising minimums and exit letters for exactly these clients.
What paperwork do international clients need at a US custodian?
The core stack is standard: a Form W-8BEN certifying foreign status and claiming any tax-treaty withholding rates on US-source income, government identification and proof of foreign residency for KYC onboarding, and the custodian's country-eligibility screening. FATCA governs how financial institutions report on US account holders abroad, and most of the world exchanges account information under the OECD's Common Reporting Standard; the United States participates through its FATCA agreements instead, which is one structural reason international families custody assets in the US at all.
Does Winthrop & Co. work with international advisors?
We work with advisors who are licensed and practicing in the United States, and their clients can be international. If you are a US-based advisor or team with a cross-border book, non-US-resident households, international families, expatriates, we help you map which independent custodians and platforms can hold your specific client countries, what transfers cleanly, and what the client conversation should sound like. We do not place advisors located or licensed outside the US.
