When an investor wants to hold money for a relatively short period, they can find various alternatives for obtaining a return without committing to a long investment horizon.

Among them are money market funds and certain P2P investments involving short-term loans. Although both can be used to manage capital over short periods, their operation and their risks are very different.

The term alone does not determine the level of risk. A six-month P2P loan remains exposed to the borrower's default risk, whereas a money market fund is exposed to different factors related to the assets it holds in its portfolio.

For this reason, before deciding between the two options it is advisable to analyse what happens to the capital, what return can be expected, what liquidity exists and what risks are being assumed.

What is a money market fund?

A money market fund is an investment vehicle that invests mainly in short-term, highly liquid debt instruments.

Its objective is usually to provide an alternative for managing liquidity with a relatively low level of volatility compared with other investment funds.

The assets it may hold include certain money market instruments and short-term debt from issuers with characteristics suitable for this type of strategy.

However, a money market fund is not a bank account or a deposit. Its value may fluctuate and the return is not guaranteed.

The fund's performance will depend on the assets held in its portfolio, on interest rates and on market conditions.

What is short-term P2P?

P2P lending allows investors to participate in loans through a platform.

When we refer to short-term P2P, we mean transactions whose maturity falls within a relatively short horizon, for example several months or around one year.

In the case of business loans, the investor finances a company and receives interest according to the agreed terms.

A short-term P2P investment may have a short maturity, but this does not eliminate credit risk.

If the borrower has difficulties repaying the loan, the recovery process may extend beyond the maturity date initially envisaged.

Money market funds vs. short-term P2P

Both alternatives can be used to manage capital over relatively short periods, but they are based on very different structures.

Feature Money market funds Short-term P2P

Asset type Money market instruments and short-term debt

Private loans

Main risk Market and credit risk of the assets

Borrower credit risk

Return Variable Depends on each loan

Horizon Short term Depends on the loan

Liquidity Generally high, depending on the fund

Depends on the loan and the platform

Capital guarantee

No No

Diversification Managed within the fund Can be carried out directly by the investor

Volatility Generally low, but present

Not necessarily reflected as daily price fluctuation

The last difference is particularly important.

The fact that a P2P investment does not show a daily market price does not mean that it carries less risk. The risk may manifest itself in another way, for example through a delay or default on the loan.

Return: which option can offer more?

There is no fixed answer.

The return on money market funds is closely linked to the level of interest rates and to the instruments held in their portfolio.

When interest rates are high, the new assets acquired by the fund may offer a higher return. If rates fall, the expected return may decrease progressively.

In P2P, the interest rate is set for each loan according to its characteristics and the risk associated with the borrower.

For this reason, certain loans may offer a higher return than can be obtained from money market instruments, but that difference is not free: it entails taking on greater credit risk.

Comparing only the return percentages may conceal this fundamental difference.

Risk: short term does not mean low risk

One of the most common mistakes is to assume that an investment is safe simply because it has a short maturity.

Consider two investments:

  • A money market fund with a six-month investment horizon.
  • A P2P loan with a six-month maturity.

The fact that both have a similar term does not mean that they carry the same risk.

In a money market fund, the investor is exposed to the performance of the assets that make up the portfolio.

In a P2P loan, there is direct or indirect exposure to the borrower's ability to repay the money.

A company may default on its obligations whether the loan matures in six months or in two years.

Therefore, term and risk are different variables.

Liquidity: an important difference

Liquidity is another aspect that should be analysed before investing.

Money market funds generally allow redemption of units to be requested in accordance with the conditions established by the fund. This may provide considerable flexibility for investors who need access to their capital.

In P2P, the money normally remains tied to the loan until maturity.

Some platforms may offer a secondary market that allows an attempt to sell a position before the loan ends. However, this depends on demand existing and on the conditions of the transaction.

Therefore, a secondary market may improve the chances of exiting, but it does not guarantee an immediate sale.

What happens if you need the money earlier?

This question may completely change the choice.

If there is a high likelihood of needing the money before the expected period ends, liquidity should carry significant weight in the decision.

In a money market fund, the investor can normally rely on redemption mechanisms subject to the conditions of the product.

In a P2P loan, by contrast, recovering the capital before maturity may depend on the existence of a secondary market or on other options established by the platform.

And there is an additional issue: even if the investment has a six-month maturity, a default may delay recovery.

For this reason, money that has a fixed and near date of use should not be invested in short-term P2P.

Capital protection

Neither money market funds nor P2P investments should be confused with a bank deposit.

A money market fund does not guarantee that the investor will recover exactly the initial capital. Its value may vary.

In P2P, there is likewise no general guarantee of capital repayment. The outcome depends on the loans made and on the borrowers' ability to meet their obligations.

Some loans may have collateral or other protection mechanisms, but these must be analysed individually.

Therefore, if the main objective is to preserve capital with specific deposit protection, these alternatives must be compared with banking products of that nature.

Diversification

The way of diversifying is also different.

In a money market fund, the investor acquires units of a managed portfolio that may contain numerous instruments.

In P2P, the investor can build a portfolio themselves by spreading the capital across different loans.

For example, instead of investing 1,000 euros in a single project, you could spread the capital across several smaller loans, provided that the platform allows this.

Diversification does not eliminate the risk of loss, but it can reduce the impact that an individual problem would have on the portfolio as a whole.

Taxation

The taxation of the two alternatives differs because the nature of the returns also differs.

In a money market fund, the tax outcome will depend on the transactions carried out by the investor and on the rules applicable to investment fund units.

In P2P, the interest earned on loans must be taken into account in the income tax return in accordance with the applicable tax rules.

In addition, losses arising from certain defaulted loans may receive specific tax treatment.

Therefore, returns should be compared, where possible, on a like-for-like basis and taking taxes and costs into account.

How much money is needed to start?

The minimum amount depends on the product.

Money market funds may have different entry minimums depending on the distributing institution and the fund.

In P2P, the minimum depends on the platform and on the conditions of each loan.

In this case, a low minimum amount can make it easier to diversify across different projects.

However, having a low entry minimum does not mean that the product is suitable for any amount. What matters is determining what percentage of your assets is being allocated to the strategy and what role it plays within the portfolio.

Which profile may each alternative be suitable for?

Money market funds

They may be of interest to investors who:

  • Are looking for an alternative for managing liquidity.
  • Have a short horizon.
  • Want to reduce volatility compared with other assets.
  • They consider the possibility of redeeming the units in accordance with the fund's terms.
  • They do not wish to select loans individually.

Nevertheless, they remain an investment and their return is not guaranteed.

Short-term P2P

It may be of interest to investors who:

  • Wish to add private debt to their portfolio.
  • Accept credit risk.
  • Seek a potentially higher return.
  • Are able to keep their capital invested for the term of the loans.
  • Wish to select and diversify across different projects.

The fact that a loan is short-term does not eliminate the risk of default.

Can they be combined?

Yes.

An investor does not necessarily have to choose a single alternative.

Money market funds may be used for the portion of the portfolio intended to manage liquidity, while P2P may form part of a higher-risk investment strategy.

For example, a person could keep part of their capital in short-term instruments and allocate another amount, not needed immediately, to diversified private loans.

The allocation will depend on each investor's risk profile, objectives and time horizon.

What to analyse before investing short term

Before deciding between a money market fund and P2P, it is advisable to answer several questions:

1. When will I need the money? 2. Can I withstand a capital loss? 3. What level of liquidity do I need? 4. Is the return guaranteed or can it vary? 5. Where does the main risk come from? 6. What costs are involved? 7. How is the return treated for tax purposes? 8. What percentage of my portfolio does the investment represent?

These questions help avoid a common mistake: choosing a product simply because it offers a certain percentage return.

Conclusion

Money market funds and short-term P2P may appear to be similar alternatives, since both allow investing over relatively short periods. However, the risk and the way each works are different.

Money market funds provide exposure to a portfolio of money market instruments and short-term debt, whereas P2P makes it possible to fund loans and take on the credit risk associated with the borrowers.

P2P may offer a potentially higher return, but that return is linked to greater credit risk and, generally, to more limited liquidity.

Money market funds, for their part, may be more suitable for managing short-term liquidity, although they do not guarantee capital or a given return either.

The key is not to confuse short term with low risk. Before choosing, investors should assess when they will need the money, what loss they could bear, what liquidity they need and what role they want the investment to play within their portfolio.

In certain cases, the two alternatives may even complement each other: one to manage liquidity and the other to seek a higher potential return by taking on greater credit risk.
