Private Banking vs Fee-Only Wealth Management: What $10M+ Investors Need to Know

Once your investable assets cross $5M–$10M, you get courted by a different tier of financial institution: JP Morgan Private Bank, Goldman Sachs Private Wealth Management, Citi Private Bank, UBS Wealth Management USA. The pitch is compelling — dedicated bankers, institutional access, concierge services. But the fee structures, regulatory standards, and service focus differ substantially from fee-only RIAs. Here's how to evaluate the choice objectively.

What is private banking?

Private banking is a bundled suite of financial services — investment management, lending, trust services, and concierge banking — offered by large banks to high-net-worth clients who meet minimum asset thresholds. Unlike retail banking or wirehouse brokerage, private banking relationships are typically assigned to a dedicated banker or team who coordinates the services.

How private banking charges you

Private bank pricing is notoriously opaque. The stated AUM fee is often just one component. A realistic all-in picture for a $10M+ private bank relationship typically includes:

• AUM advisory fee: 0.5–0.85% on managed assets. Some banks charge tiered rates that decline as AUM grows; others bundle the fee with bank services.
• Fund/product costs: Proprietary funds, structured products, and alternatives carry their own expense ratios (often 0.5–1.5%+ for alternatives). These are deducted inside the fund — they don't appear on your advisory statement.
• Structured products and annuities: Carrying costs of 1–2%+ annually in some cases. Banks earn manufacturing margins when clients hold bank-issued structured notes.
• Lending spread: If you use the bank's securities-backed lending (SBL) or mortgage products, the bank earns a spread. Clients who borrow subsidize those who don't.
• Wire, custody, and transaction fees: Varies; sometimes waived at relationship minimums.

The combined all-in cost for a private banking client — advisory fee plus embedded product costs — typically runs 1.0–2.0% of AUM annually, with variation depending on how the portfolio is structured and how much proprietary product it holds.

Fee-only RIA comparison

Fee-only RIAs that specialize in $5M–$50M households operate under a simpler and more transparent structure:

At $10M AUM, a 0.75% all-in cost difference amounts to $75,000 per year. Over 20 years at 6% portfolio growth, that differential compounds to roughly $3–4M of additional wealth — before accounting for the tax-efficiency gap from direct indexing (which fee-only RIAs deploy and private banks generally don't).

The structural difference: lending-centered vs planning-centered

The most important distinction isn't the fee — it's what drives the relationship and how the firm makes money beyond the stated fee.

Private banks are lending-centered. The bank's primary P&L engine is spread income: mortgages, securities-backed lines of credit, commercial loans, subscription lines. Your investment portfolio is partly a mechanism for collateralizing credit. The bank's incentive to keep assets on-platform — particularly in proprietary or bank-custodied products — is related to its ability to offer you credit and earn spread. This creates a structural tension: the advice you receive about asset allocation and portfolio construction is given by an institution that earns money when you borrow against those assets.

Fee-only RIAs are planning-centered. The only revenue is the advisory fee. The firm has no lending book, no product manufacturing revenue, no revenue-sharing arrangements. The incentive structure is to retain clients through performance and service quality. When a fee-only RIA recommends a portfolio structure, there's no hidden financial consideration. When they coordinate your CPA and estate attorney, they're not also trying to close a mortgage.

What private banking does well

Private banking is genuinely superior for clients with specific needs:

• Complex lending: If you need a $15M securities-backed line to fund a real estate acquisition, or a jumbo mortgage on a $4M primary residence, private banks offer integrated, high-limit credit at rates retail borrowers can't access.
• International banking: Multi-currency accounts, cross-border wire efficiency, foreign property financing. Fee-only RIAs have no bank infrastructure.
• Concierge and lifestyle services: Some private banks offer art advisory, real estate search, travel concierge, and family office-style services. Value depends on how much you use them.
• Private credit/structured deal access: At $25M+, major private banks can offer proprietary deal flow in direct lending, co-investments, and structured credit unavailable to retail investors. The catch: the bank manufactures or earns fees on this deal flow.
• Brand and relationship capital: Some business contexts benefit from a Goldman Sachs or JP Morgan Private Bank relationship. This is real but hard to quantify.

Where fee-only RIAs consistently outperform

• Tax efficiency: Fee-only RIAs can deploy direct indexing, harvest losses systematically, and coordinate Roth conversions, DAF timing, and capital-gains management without a proprietary-product conflict. The after-tax return difference is often 0.5–1.5%/yr for taxable accounts above $500K.
• Estate planning coordination: RIAs quarterback the estate attorney and CPA. Private bankers coordinate too, but the trust and estate services at large banks often carry their own product incentives (in-house trust departments, captive trust companies).
• Transparency: Form ADV Part 2A describes every fee and conflict. No need to aggregate across multiple documents.
• Alignment: The fee-only fiduciary has one job: grow and protect your wealth. No lending spread, no product manufacturing margin to chase.
• Cost at scale: The fee gap grows with AUM. At $30M, a 0.75% all-in cost difference is $225,000/year.

A hybrid approach

Many $10M–$50M households use both: a fee-only RIA managing the investment and planning relationship, paired with a private bank credit line or mortgage when needed. The RIA keeps the investment assets; the bank provides the lending facility. This gives you the fiduciary alignment on the planning side and access to institutional credit when needed — without having your investment management driven by a lending-centered institution.

Questions to ask when evaluating both

1. What is your all-in cost? Ask the private bank to sum advisory fees, fund expense ratios, and alternative investment fees on your proposed portfolio. Ask the RIA the same. Put the totals side-by-side.
2. Where does your revenue come from besides my AUM fee? A fee-only RIA should say "nowhere." A private bank will have a longer answer.
3. Who is my primary advisor? At private banks, banker turnover is common. Senior bankers move. Understand who specifically manages your relationship and what happens if they leave.
4. Do you use direct indexing? If not, why? At $1M+ in taxable assets, direct indexing is worth evaluating. Private banks have limited incentive to deploy it; fee-only RIAs don't.
5. How do you coordinate with my CPA and estate attorney? Ask for a specific example of a coordination outcome — not just "we communicate with your team."
