Custody: Who Actually Holds Your Assets

That is not an anomaly or a failure — it is how the system was deliberately built, and understanding it explains several things that otherwise look strange.

The chain

Securities are typically held in "street name", meaning registered in the name of a nominee rather than the investor. The chain generally runs: the investor, whose broker records their entitlement; the broker, or the clearing firm that holds the position on the broker's behalf; and a central securities depository, where the securities themselves are immobilised and transfers happen as book entries rather than movements of paper.

So the investor is the beneficial owner and somebody else is the registered owner, and the investor's holding is a claim recorded on their broker's books rather than a set of identified certificates with their name on.

The reason the system works this way is settlement. Moving physical certificates for every transaction was the constraint that produced the paperwork crises of the late 1960s, and immobilising the securities while moving book entries is what made high-volume trading possible at all.

What the firm is required to do with what it holds

The Customer Protection Rule — Rule 15c3-3 — requires a broker-dealer to keep customer assets separate from its own.

Two obligations do most of the work. The firm must maintain possession or control of fully paid securities and of "excess margin securities" — margin securities beyond what is needed to secure the customer's loan, defined in the rule as securities with a market value above 140% of the customer's debit balance — keeping them free of any lien and unavailable for the firm's own use. And the firm must maintain a special reserve account at a bank, held for the exclusive benefit of customers, containing an amount computed under a prescribed formula.

Which returns to the point made in the previous article, and completes it. Fully paid securities must be segregated. Margin securities that are securing a loan need not be, and may be pledged or lent under the margin agreement. So the custody arrangement a customer is actually in is determined partly by an account-type decision they may have made for unrelated reasons. The distinction is not between careful firms and careless ones — it is a rule that applies to every firm and produces different outcomes for different accounts at the same firm. A reader who wants to know how their own securities are held has to look at the account agreement rather than the firm's reputation.

What street-name holding actually changes

The issuer does not know the investor. Communications — proxy materials, annual reports, corporate action notices — travel down through the intermediaries rather than directly, which is the plumbing behind the voting chain described in Pillar 27 and the reason a record date exists at all.

Dividends and entitlements arrive via the chain rather than from the company, with each layer passing them on.

The holding is fungible. A customer owns a quantity of a security, not particular units of it — which matters not at all in ordinary conditions and matters considerably in a shortfall, since there is nothing individually identifiable to return.

And the transfer of a holding between firms is a message between intermediaries, which is why moving an account is a process with a timetable rather than an instant action.

The alternative, and why almost nobody uses it

Direct registration puts the investor's own name on the issuer's register, held in book-entry form without a certificate and without an intermediary between the investor and the company. Physical certificates remain possible for some issuers and are largely obsolete.

The trade-offs are real in both directions and this portal recommends neither. Direct registration removes the intermediary chain and with it the firm-failure exposure the next article describes. It also removes the convenience the chain provides — selling generally requires transferring the holding to a broker first, which takes time, and consolidated statements, cost-basis tracking and immediate execution are properties of the intermediated system rather than of the securities themselves.
