The primary institutions where Lightyear holds uninvested customer funds include ABN AMRO Bank in the Netherlands and AS LHV Bank in Estonia. Additionally, a portion of the funds is invested in BlackRock money market funds that hold AAA/mmf ratings from Moody’s, S&P, and Fitch.

But it is important to note what Lightyear states on their website so you fully understand how your account works, “funds held in your Lightyear account are not equivalent to a bank deposit, and therefore in the unlikely event that all appropriate safeguards fail, funds are ultimately protected by the Investor Protection Sectoral Fund only for amounts up to 20,000 EUR in total across all your multi-currency account balances. Funds are not covered by the Deposit Guarantee Sectoral Fund, as it only covers bank deposits”.

Lightyear has hired many former employees of popular brokers, banks, and e-money businesses such as Robinhood, Revolut, and Wise with the aim of breaking down some barriers with their platform.

Their main selling point is their straightforward, equitable, and transparent pricing structure, and they have a wide offering of international stocks, ETFs and MMFs to choose from (over 3,500 at present).

Wise is slightly different from the other brokers that made our list, as it is primarily an eMoney business that helps individuals seeking cost-effective solutions for international money transfers.

Even though it is an eMoney business, Wise does give you the option to hold your funds in Cash, Stocks, or Interest. When you opt for stock, Wise will select an appropriate index fund and make investments on your behalf.

If you decide to switch your funds to the ‘interest’ option, Wise will invest them in government-backed short-term loans and bank deposits. The interest earned through these investments is then passed on to you.

The downside of this for investors is that the service is currently a bit limited if your ultimate goal is to invest those uninvested funds more freely in stocks, ETFs, etc., of your choosing.

Interactive Brokers USD interest rate

Only those with accounts with a Net Asset Value (NAV) of USD 100,000 or more can receive interest at the full rate. For accounts with a NAV below USD 100,000 (or its equivalent), the interest rates are proportionate to the account size.

TD Ameritrade USD interest rate

  • What Rate is on offer? A low rate of just 0.35%.
  • How often is interest paid? Simple interest is calculated on the entire daily balance and is credited to your account monthly.
  • Are there any restrictions? TD Ameritrade does not have any restrictions on their accounts, you will earn 0.35% interest if you have $1 deposited, and the same rate if you have $1,000,00 on deposit.
  • Is your money safe? TD Ameritrade complies with the SEC’s Customer Protection Rules, which means that your assets will be segregated, and in the very unlikely event that TD Ameritrade was to become insolvent, these assets are protected from creditor’s claims.

TD Ameritrade also offers an Insured Deposit Account (IDA) cash sweep program, this is what enables you to earn interest on cash balances. As part of this program, your money will be placed with banks that are covered by FDIC insurance up to $250k. TD Ameritrade has three banks as part of the program which are Charles Schwab Bank, Charles Schwab Premier Bank, and Charles Schwab Trust Bank.

As TD Ameritrade has more than one participating bank, they can offer you a total FDIC coverage up to $500k as funds can be split between multiple banks.

Many brokerages take a hands-off approach and just give you the tools to invest as you see fit. TD Ameritrade not only gives you all the tools you need, but they are also there on the other end of the phone to help plan for your future financial needs whether they be short-term investing accounts or planning for retirement.

That is why there are five different bespoke account types based on your needs, Standard Account, Retirement Account, Education Account, Speciality Account, and Margin Trading Account.

While TD Ameritrade doesn’t pay great interest rates on your invested USD right now, they make up for it with everything else.


Investors are spoiled for choice now, with many brokers offering rates on USD cash of 5%+. A key concern for investors should also be how well their funds are protected, especially in the context of how we have seen some regional banks in the US fold in 2023, such as Silicon Valley Bank.

Thankfully the vast majority of investors will be well covered by both FDIC and SIPC insurance, but high-net-worth individuals should pay particular attention to whether the coverage is sufficient to protect them if any more banks were to have the same faith.
