How Alpaca’s High-Yield Cash Program Helps You
Whether you're building cash reserves or waiting for the right market entry, every dollar in your account should work as hard as you do. This program puts your idle cash to work, earning interest without restricting your trading activity.
Earn Interest on Eligible Uninvested Cash
When you enroll in Alpaca’s High-Yield Cash program, eligible uninvested cash may earn up to 3.56% APY.**
Note: This illustration assumes no deposits, withdrawals, trades, fees, or changes to the APY. The APY is variable and may change at any time; actual interest earned may differ.
With Alpaca, you’ll be earning more than 9x the national average2—a rate that outpaces traditional savings accounts and is highly competitive against top B2C fintech offerings.
FDIC Pass-Through Insurance Up to $2.5M
Alpaca helps protect your High-Yield Cash with up to $2.5 million in FDIC pass-through insurance through participating program banks.*** This insurance acts as a safety net, covering your funds even in the unlikely event of a bank failure. As we expand this program, we will continually seek to increase coverage limits to extend protection for high-net-worth and institutional customers.
Liquidity and Flexibility
You can access your funds at any time, enabling you to withdraw, transfer, or use them as buying power when opportunities arise. Enjoy the same-day flexibility you expect from your trading account, with the added benefit of earning interest when funds are uninvested.

Alpaca Securities offers a cash management program pursuant to the FDIC Bank Sweep. Customer funds are treated differently and are subject to separate regulatory regimes depending on whether customer funds are held in their brokerage account or within the FDIC Bank Sweep. Alpaca Securities is a member of the Securities Investor Protection Corporation (SIPC), which protects securities customers of its members up to $500,000 (including $250,000 for claims for cash). The Federal Deposit Insurance Corporation (FDIC) insures up to $250,000 per deposit against the failure of an FDIC member bank. Customer funds held in brokerage accounts are SIPC insured, but are not eligible for FDIC insurance coverage. Funds maintained in the FDIC Bank Sweep are intended to be eligible for pass-through FDIC insurance coverage but are not covered by SIPC. FDIC insurance does not protect against the failure of Alpaca, Alpaca Securities, or their affiliates, nor against malfeasance by their employees. Program banks that participate in the FDIC Bank Sweep are not members of SIPC, and therefore, funds held in the Program are not SIPC protected. Please see alpaca.markets/disclosures for important additional disclosures regarding Alpaca Securities brokerage offering, as well as FDIC Bank Sweep terms and conditions.
Alpaca Securities customers who enroll in the FDIC Bank Sweep are potentially eligible for enhanced FDIC pass-through insurance coverage. Neither Alpaca nor Alpaca Securities is FDIC-insured. FDIC pass-through insurance coverage is subject to various conditions. The Program’s enhanced FDIC insurance coverage is limited to the aggregate number of participating program banks, multiplied by the FDIC insurance limit (i.e., $250,000). The total number of participating banks is subject to change, and Alpaca Securities may not utilize all program banks at all times, which will affect the Program’s insurance coverage amount. In addition, if a customer has a direct banking relationship with a program bank, this may affect the amount of funds that are potentially eligible for FDIC pass-through insurance coverage. There is no guarantee that customer funds will be allocated in a way that maximizes possible FDIC pass-through insurance coverage. Please see alpaca.markets/disclosures for further information and important disclosures.
High-Yield Cash API is subject to, among other things, Alpaca’s API terms and conditions. In addition, customer access to the FDIC Bank Sweep is subject to, among other things, the Alpaca Customer Agreement, Alpaca Terms and Conditions, and the Alpaca FDIC Bank Sweep Program Terms and Conditions. Please see alpaca.markets/disclosures for further information and important disclosures.
All investments involve risk, and the past performance of a security, or financial product does not guarantee future results or returns. There is no guarantee that any investment strategy will achieve its objectives. Please note that diversification does not ensure a profit, or protect against loss. There is always the potential of losing money when you invest in securities, or other financial products. Investors should consider their investment objectives and risks carefully before investing.
Commission free trading is available to Alpaca's retail customers. Commission free trading means that there are no commission charges for Alpaca self-directed individual cash brokerage accounts that trade U.S.-listed securities and options through an API. However, certain arrangements with authorized business partners or the use of the Elite Smart Router as part of the Alpaca Elite offering may preclude commission free trades by Alpaca Securities. Please refer to the Brokerage Fee Schedule for more information. Relevant regulatory fees may apply. Alpaca reserves the right to charge additional fees if it is determined that order flow is non-retail in nature.
This is not an offer, solicitation of an offer, or advice to buy or sell securities or open a brokerage account in any jurisdiction where Alpaca Securities is not registered or licensed, as applicable.
