Industry Overview
Custody Banks sits within the financials sector. The first numbers to compare across companies here are assets under custody and administration, fee revenue growth and net interest margin. The outside forces that move them are listed under Primary Macro Drivers.
Key Industry Metrics
- Assets under custody and administration: Value of securities and cash safekept or administered for institutional clients. It underlies fee revenue and moves with markets as well as with new mandates.
- Fee revenue growth: Growth in service, trading and asset-based fees. Stable fee growth shows client wins and pricing, and is less volatile than interest income in this business.
- Net interest margin: Spread between interest earned on assets and paid on client deposits. Large low-risk balances make it sensitive to policy rates and to how much client cash stays in deposits.
- Pre-tax margin: Operating profit before tax as a share of revenue. Because the business is scale driven, margins show efficiency, and they widen when assets grow faster than costs.
- Securities lending revenue: Income from lending client securities to borrowers, earned as a share of fees. It varies with demand to borrow securities, so it is secondary and can be uneven.
Primary Macro Drivers
- Equity and bond market levels: Fees follow the value of assets held, so higher stock and bond prices raise assets under custody and fee revenue, while declines reduce them.
- Interest rates: Rate levels set income on large client deposits and securities holdings, shown in net interest margin, and affect the cost of client cash.
- Trading and foreign exchange volatility: Client foreign exchange and trading volumes rise with currency volatility, increasing foreign exchange trading and securities lending revenue.
- Outsourcing by asset managers: Managers handing operations to a custodian add assets under custody, and scale lowers cost per account, lifting pre-tax margin.
Major Risks
- Fee compression: Competition and big client negotiations push down fees per dollar held, shrinking fee revenue growth. Watch fee revenue growth against assets under custody.
- Operational and technology failures: A system failure, settlement error or breach can lead to loss of clients and compensation costs. Watch operational loss and technology disclosures.
- Regulatory capital rules for large banks: Larger banks must hold more capital and meet stress tests, which limits buybacks and balance sheet growth. Watch capital ratios and rule changes.
- Client concentration: A handful of clients provide much of the revenue, so a lost mandate can cut results. Watch client wins and losses and the stated largest client share.
