Private banking is a bundled financial service for wealthy individuals and families, generally requiring at least $1 million in investable assets, that pairs you with a dedicated relationship manager who coordinates investment management, lending, tax planning, and estate strategy under a single institution. Instead of walking into a branch and picking from a standard menu, you get one point of contact who pulls in the bank’s specialists as your situation calls for them. The model is built for people whose finances are complicated enough that off-the-shelf products leave gaps.
How It Differs From a Regular Bank Account
The defining feature is the relationship manager. This person is your single point of contact and the quarterback for the bank’s internal teams. Need a custom loan structure? The relationship manager loops in credit. Rethinking your estate plan after a business sale? They bring in trust and tax. You are not calling an 800 number and explaining your situation from scratch each time.
The scope also runs well past checking accounts and CDs. A private bank aims to handle your whole picture: personal investments, business holdings, real estate, philanthropy, and the connections between them. If you sell a business and want the proceeds to fund a charitable trust that also reduces estate tax exposure, the bank coordinates that across departments rather than leaving you to stitch together advice from three unrelated firms.
Clients fall into two broad tiers. High-net-worth individuals generally hold $1 million or more in investable assets; ultra-high-net-worth clients typically exceed $10 million. Banks price and staff accordingly, and the higher tiers can unlock access to the bank’s chief investment officer or invitations to co-invest alongside the bank’s own capital.
What You Actually Get
Investment Management
Private bank portfolios reach beyond publicly traded stocks and bonds into alternatives: private equity, hedge funds, venture capital, and direct real estate deals. Most of these funds are legally restricted to investors who qualify as accredited, which requires either a net worth above $1 million excluding your primary residence or individual income above $200,000 in each of the prior two years (or $300,000 jointly with a spouse) with a reasonable expectation of the same going forward.1U.S. Securities and Exchange Commission. Accredited Investors The most exclusive funds require qualified purchaser status, meaning at least $5 million in net investments for individuals.2U.S. Securities and Exchange Commission. Defining the Term Qualified Purchaser Under the Securities Act of 1933 The bank handles verification and provides the pipeline.
Portfolios are built around your specific risk profile rather than slotted into a model. The bank might structure a direct co-investment in a commercial real estate development rather than simply allocating to a publicly traded REIT. The tradeoff is liquidity: these positions can lock up your money for years, so the portfolio has to account for when you’ll actually need cash.
Trust and Estate Work
This is where private banking earns its keep for multi-generational families. The 2026 federal estate tax exemption is $15 million per person, so a married couple can shield up to $30 million from estate tax.3Internal Revenue Service. What’s New – Estate and Gift Tax Families with wealth above that line, or those worried about future legislative changes, lean heavily on the bank’s trust and estate team.
Irrevocable trusts are the workhorse. Assets you transfer into one generally leave your taxable estate, reducing what the 40% federal rate can reach. The bank often serves as the corporate trustee, providing administration and continuity that doesn’t depend on any one person’s availability. Corporate trustee fees typically run between 0.25% and 1% of trust assets annually, with the percentage declining as the trust grows. The generation-skipping transfer tax exemption, also $15 million per person in 2026, lets wealth skip a generation without an additional layer of tax.3Internal Revenue Service. What’s New – Estate and Gift Tax
Philanthropic planning fits into the same framework. The bank can help you set up a private foundation for maximum control over grantmaking or a donor-advised fund for a simpler, lower-overhead approach. Both offer immediate tax deductions and differ in administrative burden, minimum funding, and disclosure.
Specialized Credit
One of the most popular products is the securities-based line of credit, or SBLOC. You borrow against your investment portfolio without selling anything, which avoids triggering capital gains on appreciated positions, and interest rates are typically lower than personal loans or standard credit lines.4FINRA. Securities-Backed Lines of Credit Explained
The risk is real. If your portfolio drops in value, the bank can issue a maintenance call requiring you to post more collateral or repay part of the loan within two or three days. If you can’t meet it, the bank can liquidate your securities to cover the shortfall, often without advance notice.4FINRA. Securities-Backed Lines of Credit Explained A forced sale during a downturn locks in losses at the worst time.
Beyond SBLOCs, private banks lend against less conventional collateral: fine art collections, private aircraft, commercial real estate development projects. Repayment terms and covenants are tailored to the asset’s cash flow, and collateral haircuts on a portfolio of municipal bonds will look very different from those on a concentrated single-stock position. That willingness to underwrite bespoke deals is a major draw for clients whose wealth is tied up in assets that are hard to finance anywhere else.
Who Qualifies and How Onboarding Works
The minimum generally starts around $1 million in investable assets for basic private banking, with the most exclusive ultra-high-net-worth groups requiring $5 million to $10 million. “Investable assets” typically means liquid holdings like stocks, bonds, and cash equivalents. Home equity and the value of a closely held business are generally excluded from that count, even though they add the kind of complexity the bank is well positioned to manage.
The dollar figure isn’t the whole story. A client with $3 million spread across international trusts, a business interest, and multiple currencies presents exactly the kind of complexity private banking exists for. Someone with $5 million sitting in a single domestic savings account may not need the full service suite at all.
Opening the relationship takes more than opening a checking account. Federal anti-money laundering rules require the bank to verify your identity through a Customer Identification Program, collecting at minimum your name, address, date of birth, and tax identification number. Business accounts also need corporate registration documents and information about ultimate beneficial owners. High-value clients often face enhanced due diligence, including screening against global sanctions lists and politically exposed person databases. Plan on several weeks, not days.
What It Costs
The dominant model is an annual fee calculated as a percentage of assets under management. Industry averages hover around 1% for portfolios in the low millions, with rates declining as the asset base grows. A client with $50 million or more can often negotiate below 0.50%. The sliding scale is designed to encourage consolidation: the more you park with one institution, the lower your blended rate.
Services outside routine portfolio management often carry separate charges. Trust administration, complex estate planning, and family office services may be billed hourly or covered under a flat annual retainer. Some banks aim for an all-in arrangement where the AUM fee covers investment advice, performance reporting, and basic financial planning, but transaction-based charges can still appear for specific brokerage trades or foreign exchange. Ask for the full schedule before signing on, and pay attention to which services are bundled and which trigger extra costs.
One point catches people off guard: investment advisory fees are no longer deductible on your federal return. The Tax Cuts and Jobs Act eliminated the deduction for miscellaneous itemized expenses in 2018, and that elimination was made permanent by subsequent legislation. A 1% AUM fee on a $5 million portfolio costs you $50,000 a year with no tax offset. That makes fee negotiation and service comparison matter more than they used to.
The Standard of Care You’re Actually Getting
Not all private banking advice carries the same legal standard, and the distinction matters more than most clients realize. When the bank’s advisory arm operates as a registered investment adviser, it owes you a fiduciary duty, meaning it must act in your best interest on an ongoing basis, including a duty to monitor your portfolio over time. When the bank’s brokerage arm makes recommendations, it operates under SEC Regulation Best Interest, which requires acting in your best interest at the time of the recommendation but does not impose the same ongoing monitoring obligation.5U.S. Securities and Exchange Commission. Regulation Best Interest – The Broker-Dealer Standard of Conduct
Many private banking relationships blend both. Your managed investment account may fall under the fiduciary standard while a one-off bond purchase through the brokerage desk falls under Regulation Best Interest. Ask your relationship manager directly which standard applies to each service you’re receiving. The answer should be clear and specific, not a vague assurance about always putting clients first.
Insurance Limits You Still Live With
FDIC insurance covers bank deposits up to $250,000 per depositor, per insured bank, for each account ownership category. For someone with $5 million in cash, that standard limit covers a fraction of the total. Private banks help maximize coverage by structuring deposits across different ownership categories (individual, joint, revocable trust) and sometimes by using deposit networks that spread cash across multiple FDIC-insured banks behind the scenes.6FDIC. Your Insured Deposits
Investment accounts are a different story. FDIC insurance does not cover stocks, bonds, mutual funds, or other securities.6FDIC. Your Insured Deposits If the brokerage fails, SIPC covers up to $500,000 in securities per customer, including a $250,000 limit for cash held at the brokerage.7SIPC. What SIPC Protects For a client with tens of millions in a single brokerage, the SIPC ceiling is essentially a rounding error. The gap is worth understanding when deciding how to distribute assets across institutions.
Proprietary Product Conflicts
Private banks sometimes steer client portfolios toward the bank’s own proprietary investment products, like in-house mutual funds or pooled vehicles. The bank earns additional fee income from managing those products on top of the advisory fee you’re already paying. Federal bank examiners have flagged situations where fiduciaries continued investing in poorly performing proprietary funds to maintain assets under management, generating fee income at the beneficiary’s expense.8FDIC. Compliance/Conflicts of Interest, Self-Dealing and Contingent Liabilities
Not every proprietary product is bad. Some are genuinely competitive. But ask your relationship manager what percentage of your portfolio sits in the bank’s own products, whether comparable third-party alternatives were considered, and how the bank’s compensation changes based on which products are picked. The answers reveal a lot about whether the bank’s incentives line up with yours.
Reporting Duties If You Hold Assets Abroad
Clients with accounts or assets outside the United States face two separate federal reporting obligations, and the penalties for missing either are steep. The Report of Foreign Bank and Financial Accounts (FBAR) is required if the combined value of your foreign financial accounts exceeds $10,000 at any point during the year. You file FinCEN Form 114 electronically through the BSA E-Filing System, due April 15, with an automatic extension to October 15. Whether the accounts generate taxable income is irrelevant; the reporting obligation is triggered by account value alone.9Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR)
FATCA reporting on IRS Form 8938 is separate, with higher thresholds that vary by filing status and whether you live in the U.S. or abroad.10Internal Revenue Service. Do I Need to File Form 8938, Statement of Specified Foreign Financial Assets Many private banking clients with cross-border holdings owe both, since FBAR and FATCA cover overlapping but distinct categories.
Your bank’s advisory team should coordinate this compliance, but the legal obligation is yours personally. Penalties for missed FBAR filings can reach $10,000 per violation for non-willful failures, with significantly higher consequences for willful ones. Keep records for each reported account, including name, number, bank name and address, account type, and maximum value during the year, for at least five years from the FBAR due date.9Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR)
When It Isn’t Worth It
Private banking is not a universally better version of regular banking. If your financial life is relatively straightforward, the cost-to-benefit ratio can be poor. Paying 0.75% to 1% a year on a portfolio that could be managed with low-cost index funds and a good estate attorney is expensive convenience, not sophisticated strategy. The value shows up when your situation genuinely requires coordination across investment, tax, credit, and estate planning, and when doing it yourself or across multiple firms would cost you more in missed opportunities than the fees.
At higher wealth levels, a multi-family office is worth comparing. These firms, typically structured as registered investment advisers, can offer more open-architecture investment selection and often operate under an unambiguous fiduciary standard, so they are not pushing proprietary products. But many lack the lending capabilities, global custody, and institutional balance sheet of a large private bank. Some families use both, keeping their core advisory relationship with an independent office while tapping the private bank for lending and custody.
Portability is the last thing to think through before you commit. Some private bank investment products, particularly proprietary funds and structured notes, cannot easily transfer to another institution. If you decide to leave, you may face liquidation and the tax consequences that follow. Account transfer fees are relatively modest; the real cost is unwinding positions designed to live inside that bank’s ecosystem. Before committing assets to any proprietary vehicle, ask what happens if you want to move those holdings somewhere else in three years.
