Earn up to 4.0% on USD at Interactive Investor

Earning interest on uninvested cash in a brokerage account is a useful, low-risk way to preserve the value of your money. However, there can be significant differences among brokers when it comes to interest: some don't pay anything, while some brokers pay higher rates than banks.

Interactive Investor pays interest on uninvested cash in several currencies: you can earn up to 4.0% on USD, for example.

What are the benefits of getting interest on uninvested cash?

  • Earn additional money without active investing, preserving its value against inflation.
  • Keep cash easily accessible while generating returns.
  • By leaving idle cash on the account, you can save on potential withdrawal or conversion fees.
  • Offers a low-risk, hassle-free option compared to market investments.
  • Affords flexibility, providing time to plan investments without losing potential earnings.

While earning interest on your uninvested cash is great, there are a few things to keep in mind:

  • The advertised interest rate is annual, so you'll need to divide this by the number of months or days to understand your actual earnings. Interest is typically accumulated daily but paid monthly.
  • You may need to pay tax on the interest you earn. The tax typically depends on your country of residency, and is not deducted by the broker. It is your responsibility to report and pay the taxes.
  • In most cases, there's little reason to worry about safety when keeping cash in your broker account. In the US, for example, cash holdings are insured up to $250,000.
  • Be on the lookout for any special conditions the broker may set in order to pay interest, such as a minimum balance requirement.
  • If you maintain a broker account solely for the purpose of earning interest on your cash, choose a broker that doesn't charge an inactivity fee or regular account fee.

Interest rates at Interactive Investor are average

In order to have a verdict on how Interactive Investor stacks up against other brokers on the market with regard to interest rates on uninvested cash, we looked at several factors:

  • How many currencies it pays interest on: just one or several? Brokers that pay interest on only one currency score lower than others.
  • What the interest rates are: naturally, the higher the better.
  • Are there any conditions? We took two cases: the maximum interest you can earn, and the interest you can earn on $10,000. Brokers that offer interest already on low amounts, without any conditions, got a better rating.

Based on these factors, we found that Interactive Investor's overall offering for interest on uninvested cash is average.
