Best Money Market Fund to Invest in UK

When searching for the best money market fund UK – there are several key metrics that you need to focus on.

This should include:

  • What investment vehicles the money market fund holds
  • How much risk is associated with the underlying money market instruments
  • The performance of the money market funds over the past 5-10 years
  • How much liquidity the money market fund attracts
  • What pricing structure the money market fund has in place

To save you countless hours of research, below we discuss the best UK money market funds to consider right now.

1. Vanguard Sterling Short-Term MMF – Overall Best Money Market Fund UK

If you are looking for the best money market fund UK that is denominated in GBP – you might want to consider the Vanguard Sterling Short-Term MMF. As the name suggests, the MMF concentrates on financial instruments that are priced in pound sterling – which ensures that you avoid the risks associated with currency fluctuations.

In terms of what instruments the Vanguard Sterling Short-Term MMF holds – this is a combination of UK Gilts (government-issued bonds), certificates of deposits issued by banks and financial institutions, fixed-rate bonds, and short-term corporate bonds. According to Vanguard itself, this money market fund carries a risk rating of 1/5 – which ensures your exposure to loss is minimal.

Vanguard Sterling Short-Term MMF money market fund

Looking at the financials, this Vanguard fund carries an ongoing expense ratio of 0.12%. This means that for every £1,000 invested – you’ll pay an annual fee of just £1.20. The Sterling Short-Term Money Market Fund was actually only launched in 2019 – so we have limited data in terms of financial performance.

What we do know is that since its inception date – the fund was grown by 0.55%. Although such small returns are just the nature of MMFs, this is below the rate of inflation. As such – and as advised by Vanguard itself, this fund is not suitable for long-term growth. On the contrary, the fund offers a risk-averse way to protect your wealth from economic uncertainty.

2. Vanguard Treasury Money Market Fund –  Best Money Market Fund UK for US Treasuries

Although no financial instruments are truly risk-free – US Treasury Bills are arguably the go-to safe haven during times of economic unknowns. For those unaware, Treasuries are bonds issued by the US government. They come with various maturity dates – ranging from a few months up to a hundred years.

Crucially, as US Treasuries are backed by the US Federal Reserve, the chances of default are virtually zero. As such, they offer a great way to hedge against the wider financial markets. We found that the best money market fund UK for this purpose is offered by Vanguard.

Vanguard Treasury Money Market Fund (VUSXX)

The fund – which comes with an annual expense ratio of just 0.09%, has over 80% of its holdings in US government-issued debt. Once again, don’t expect any sizable returns on this MMF, as over the past 10 years it has averaged annual gains of just 0.55%. With that said, if you go back to its inception date of 1992 – the fund has averaged 2.37%.

3. Federated Hermes Prime Cash Obligations Fund –  Best Money Market Fund UK for Diversification

What we like about the Federated Hermes Prime Cash Obligations Fund is that it offers a more diversified approach to hedging. For example, the MMF holds short-term debt instruments from both corporations and the US government. Regarding the latter, this includes a variety of US Treasury debt and US government agency repurchase agreements.

More than 26% of the portfolio is held in asset-backed commercial papers, and 18% in financial company commercial papers. There are also holdings in bank certificates of deposits, tender option bonds, and variable rate demand notes. Looking at its corporate-based short-term debt – these are issued by major players in the investment banking space.

This includes JPMorgan Chase, Credit Suisse Group, Mizuho Financial Group, and Societe Generale. On top of being well-diversified, this money market fund has generated somewhat attractive returns. For example, since its inception, this stands at 2.60% per year. Over the past three years, the fund has averaged 1.50% annually.

4. Invesco Money Fund (UK) –  Best Money Market Fund UK for High-Grade Debt Securities

The Invesco Money Fund (UK) is another MMF that focuses on high-grade debt securities that are issued in pound sterling. Once again, this is ideal if you are based in the UK and looking for a short-term hedging strategy – as you don’t need to worry about currency risk. 

There is a fairly even split between bonds and cash at 53% and 47% respectively. Regarding the former, some of the largest debt issuers include Societe Generale (5.36%), Nestle Holdings (5.26%), Volkswagen Financial Services (5.00%), and the European Investment Bank (4.85%). As you likely know, these are highly stable institutions with a rock-solid balance.  

Invesco Money Fund (UK) (Accumulation No Trail)

Looking at the returns of this UK money market fund – average annual returns over a 10-year period stand at just over 0.42%. This translates into 10-year growth of 4.32% – which doesn’t get anywhere close to UK inflation levels. As such, this MMF is only suitable for short-term hedging and wealth protection strategies.

5. iShares Core U.K. Gilts UCITS –  Best Money Market Fund UK for Gilts

If you are looking for an MMF that invests exclusively in UK government bonds – it might be worth considering the iShares Core U.K. Gilts UCITS. Technically, this iShares fund is actually an ETF. However, it carries all of the same characteristics as a conventional money market fund.

iShares Core UK Gilts UCITS ETF money market fund

After all, you are investing in high-grade UK Gilts – so your exposure to risk is minimal. Additionally, this is one of the cheapest money maker funds available in the market – with iShares charging just 0.07% per year. In terms of maturity, there are Gilts with a duration of less than 12 months – right up to 20 years and more. As such, this offers a good blend of yields.

What are Money Market Funds?

Money market funds are an investment product that focuses on short-term securities. These securities are deemed very low-risk – and typically include a blend of government-issued bonds like US Treasuries and UK Gilts, alongside high-grade corporate bonds. The purpose of investing in a money market fund is not to generate long-term investment or growth.

what is money market fund

On the contrary, they offer a way to protect and hedge your wealth. For example, if it appears that the stock markets are in a downtrend trend – institutional investors might move their capital into a money market fund. In doing so, this allows them to ‘hold fire’ until it becomes clearer whether the downward trend is temporary or signs of a prolonged bear market.

  • In essence, a money market fund works much the same as a conventional mutual fund or ETF.
  • This is because the fund will be managed by a large-scale investment house – such as Vanguard or iShares.
  • In turn, you can enter and exit a money market fund investment at any time – so your capital is liquid.
  • Plus, you will be entitled to your share of any dividends that the money market fund receives.

However, unlike an ETF or mutual fund – the overarching objective with an MMF is capital preservation – and not financial gain.

Why Invest in Money Market Funds?

If you’re looking to target long-term financial growth – then money market funds will not be for you. This is because they offer a much lower rate of return than other fund types – such as major stock indices like the FTSE 100 or Dow Jones. Although money market funds are not suitable for long-term capital growth – there are many reasons why they might be suitable for your short-term investment financial goals.

This includes:

Record Low Bank Interest Rates

The vast majority of UK current accounts pay just a fraction of 1% per year in interest. You might come across a headline offer that claims to pay a more attractive return on your savings, albeit, there are often unfavourable conditions attached.

For example, there is usually a very small limit on how much of your current account balance benefit from the higher rate. In other cases, you need to have a premium current account  – which defeats the objective as you need to pay a monthly fee. Taking all of this into account, some UK investors will instead look to put their cash into a money market account.

On the one hand, the rate of return will still be very modest. But, in most cases, the UK money market funds will pay more than a traditional current account.

MMFs Possess High Liquidity Levels

As we briefly covered earlier, MMFs are liquid – even though they often hold illiquid assets like corporate bonds. This is because the best money market funds UK is publically traded – meaning that you can cash out your investment at any time during standard market hours.

This is crucial – as it means your money is never tied up for more than a couple of days – taking into account brokerage withdrawal times.

Hedge Against the Stock Markets

The stock markets – especially those located in the US, have been on an upward trend for almost a decade. As history suggests, the wider markets will always go through trends – both upwards and downwards.

As such, many argue that it is only a matter of time before we see the next prolonged bear market. When it does appear that this is the case, experienced investors will look to take their capital out of the stock market and put it into a low-risk fund such as an MMF.  This allows investors to preserve their capital until it’s time to re-enter the stock market.

Money Market Funds vs ETFs

We mentioned earlier that money market funds are not too dissimilar to ETFs. This is because both financial instruments are run and operated by large-scale institutions,which will often hold a basket of diversified assets, and generate returns via an increased NAV (Net Asset Value) and dividends.

However, it must be noted that ETFs are typically tasked with tracking a specific market – meaning that they are passively managed.

On the other hand, money market funds are actively managed – as the provider will determine which low-risk debt securities to buy and sell. After all, the main objective of a money market fund is to preserve capital – so it must proactively make risk-averse investment decisions.

Best Money Market Funds Brokers UK

If you’re ready to invest in a money market fund today – you will first need to sign up with a suitable broker. In searching for the best MMF platform – you need to consider fees, minimum account balances, payments, safety, and more.

The only way that you can get your annual fee down to 0% is to invest more than £2 million. The minimum fund investment at Fineco Bank is a reasonable £100 – which is perfect if you wish to start off with small amounts. We also like the Fineco Regular Investment Plan.

How to Invest in Money Market Funds on Fineco Tutorial

If you’re ready to invest in a money market fund right now – the guidelines below will walk you through the process with FCA-regulated broker Fineco Bank.

Step 1: Open an Account

Like all stock brokers in the UK, you will first need to open an account with Fineco Bank. To do this, head over to the provider’s homepage and click on the ‘Open Account’ button.

You will then be asked a series of questions about who you are. For example, you’ll need to supply your full name, home address, and date of birth – as well as your contact details. You also need to supply your National Insurance Number.

Step 2: Account Verification

Unlike eToro, the account verification process at Fineco Bank is a little more long-winded. This is because the broker is unable to verify your ID automatically. Nevertheless, most account verifications are completed within 1-2 working days.

All you need to do is upload a copy of your passport or driver’s license. If Fineco is unable to verify your home address through the data you have provided – it might also ask for a recently issued utility bill or bank account statement.

Step 3: Transfer Funds

Once your account is verified, you can then proceed to make a deposit. The only option here is via a UK bank transfer. As such, Fineco will display its account details on-screen, alongside your unique deposit reference. It’s important that you supply this reference when you complete the transfer to avoid delays. The minimum deposit is £100 and there are no transaction fees.

Step 4: Choose Money Market Fund and Invest

Now that your Fineco account has been funded, you can process to invest in your chosen money market fund. Once you find the MMF that interests you, complete an order by entering your stake. Once you confirm the order, the funds will be taken from your account balance.
