Goldman Sachs

Goldman Sachs is based in New York. Advisory, equity and debt underwriting, financing, and trading are the institutional businesses, and asset and wealth management is the growing fee book beside them.

Prime brokerage is the specific dependency: hedge funds clear swaps, stock loans, and margin at a small set of dealers, and Goldman is one of the firms that can hold that financing. Leaving a prime broker means moving positions, collateral, and reporting, which funds do not do casually.

The consumer experiment around Marcus was scaled back, so the competitive map is institutional clients and wealth clients, not a national branch bank. League-table share in mergers and equity issuance is the public scoreboard against Morgan Stanley and JPMorgan.

Advisory mandates are won deal by deal and do not lock a client the way a prime-brokerage account does.

Prime-brokerage balances and stock-loan inventory are a concentrated dealer market.

Wealth and asset-management fees are the more recurring revenue beside the trading book.

A hedge fund that uses Goldman as a prime broker depends on its margin, locate, and reporting systems.

Corporate boards hiring an advisor can switch banks on the next deal, which keeps that side contestable.
