Our verdict
Lightyear’s High-Interest Vaults give customers a way to earn interest on uninvested cash by placing it into low-risk money market funds managed by BlackRock. These are easy-access, variable-rate investment products available in GBP, EUR and USD, designed to track short-term interest rates such as the Bank of England overnight rate.
What are Lightyear High Interest Vaults?
We rate Lightyear’s Vaults highly as they are designed for investors who want their idle cash to earn a market-linked return while remaining easy to access, rather than sitting uninvested in a brokerage account.
Lightyear's High Interest Vaults are an easy-access cash investment product with variable rates, and there are separate vaults for deposits in Sterling, Euros and US dollars. Currently, the Sterling Vault offers around 3.77% AER (variable), with interest calculated daily and paid monthly. There are no minimum or maximum deposit limits, so users can start from £1 and add unlimited amounts.
How do Lightyear Vaults differ from holding cash from savings accounts?
Unlike a traditional savings account, the Vault is an investment product rather than a bank deposit. Your money is invested in AAA-rated money market funds, meaning capital is at risk and FSCS protection does not apply to funds held within the money market fund itself.
What is your money actually invested in?
Cash in the Sterling Vault is placed into funds such as the BlackRock ICS Sterling Liquidity Fund, which invests in diversified short-term instruments like treasury bills, commercial paper, certificates of deposit and repurchase agreements. This spreads risk across multiple institutions rather than relying on a single bank.
Is it cheaper to buy the money market fund directly?
Lightyear charges a 0.25% annual fee on money held in the Sterling Vault. While investors could theoretically access similar institutional money market funds directly, minimum investments can run into hundreds of millions, so Lightyear provides retail access to these products with no minimum deposit.
