What Is the Difference Between ACATS and a Wire Transfer to a Brokerage?

Updated July 9, 2026 5 min read

Funding a new brokerage account and moving an existing one sound similar, but they rely on two entirely different systems, and mixing them up is a common source of confusion for anyone consolidating accounts.

The short answer

ACATS (Automated Customer Account Transfer Service) is a standardized system for moving an entire account’s holdings — stocks, funds, cash, and all — directly from one brokerage to another. A wire transfer, by contrast, simply moves cash from a bank or another account into a brokerage, with no securities involved. They solve different problems and aren’t interchangeable.

What ACATS actually moves

An ACATS transfer is built to carry a full account: individual securities, cash balances, and in many cases the cost basis history attached to those securities. It’s the mechanism most people use when consolidating accounts at a new firm without wanting to sell everything first. Because it moves in-kind positions rather than cash, it avoids triggering a taxable sale simply for the act of transferring, which is one of its biggest advantages over liquidating and starting over.

What a wire transfer actually moves

A wire transfer is purely a cash movement, distinct from a wire transfer versus an ACH transfer between bank accounts, though the underlying idea of moving cash electronically is similar. It takes money from a bank account, or sometimes another brokerage account, and deposits it into a brokerage account as cash — nothing else comes with it. There’s no concept of “holdings” in a wire; if you want the equivalent investments in the new account, you’d need to buy them yourself once the cash lands. Wires are generally used for funding a new account, adding cash to an existing one, or withdrawing funds, not for consolidating existing investment positions.

Key differences at a glance

When each one makes sense

Choosing between them depends on what’s actually being moved and why. Someone consolidating a full portfolio at a new firm without wanting to sell first typically needs an ACATS transfer. Someone simply adding fresh cash to fund new purchases, or moving money that’s already in cash form, is usually looking for a wire. It’s also possible to use both in sequence — an ACATS transfer for existing holdings and a wire for additional cash — since they aren’t mutually exclusive tools.

The takeaway

The distinction comes down to form: ACATS carries investments as they are, wires carry only dollars. Knowing which one a situation calls for avoids the common mistake of selling a portfolio unnecessarily just to move it, or expecting a cash wire to somehow bring your old holdings along with it.
