The highest-yielding money market funds to park your cash in

Central bank interest rate rises mean that investors can finally get a good return on their cash. In the UK, the Bank of England base rate is now 5%. Interest rates peaked at 5.25% but are beginning to fall as inflation has dropped below 2%. Economists think that UK interest rates could end 2024 at around 4.25%. 

Interest rates influence bond yields, as well as the returns from easy-access and fixed-term savings accounts.

Investors have a number of options. While they could buy UK government bonds (gilts), which yield around 4%, they could also stray into the bond market, where yields are even higher. However, bond prices can be very volatile, and investors could be hit with capital losses even if the income is stable.

Savings accounts are another option, but yields tend to lag bond market equivalents. Moreover, unless the account is inside a cash ISA, where returns are lower, savers may have to pay tax on their returns.

Basic-rate taxpayers (up to £50,270 annual income) get a £1,000 tax-free savings allowance, while higher-rate taxpayers (up to £125,140 annual income) get £500 and additional rate taxpayers (earning more than £125,140) get nothing. Any savings interest above the thresholds is taxed at income tax rates.

Money market funds could fit the bill

Money market funds are a viable in-between option, offering the income similar to gilts maturing soon, but without the complexity, while also mitigating the risk of bond price fluctuations. They can be held inside ISAs and SIPPS.

They own a diversified basket of safe bonds that are due to mature soon, normally within just a couple of months, meaning that investors can earn an income on their cash with minimal risk. They can also put money into bank deposit accounts and take advantage of other “money market” instruments.

Fund industry trade body the Investment Association (IA) categorises money market funds into two buckets: short-term and standard term funds.

Short-term funds are lower risk. Fund managers try to ensure the highest possible level of safety by keeping very short duration bonds and high-quality bonds in the portfolio.

Standard money market funds generally deliver slightly higher returns by owning bonds that have slightly longer maturity dates.

The interest paid by money market funds will fluctuate with bond market yields, which are closely linked to central bank interest rates. This means they will rise when yields rise, but will fall when yields fall. As interest rates are expected to keep dropping this year and next, yields on money markets are also likely to drop. 

 Advantages of a money market fund

• Very low risk, with the portfolio likely to at least hold its value and also pay out a modest income
• Diversified, meaning investors are not exposed to a single bond failing and can withdraw their money easily
• Can be held in a tax-friendly wrapper, such as an ISA or SIPP.

Disadvantages of a money market fund

• Investments may fall in value, unlike savings accounts
• Not suitable for growing savings over the long term as yields are typically below inflation
• Sensitive to interest rate fluctuations, with lower rates leading to lower yields. Yields rise when interest rates rise
• The Bank of England warns that in times of market panic and a rush to cash, there may be liquidity issues in money market funds.
