The idea

Liquidity in investing is how easily and cheaply an investment can be turned into cash. Shares of large companies can usually be sold within days; property can take months; some investments lock money away for years or charge to leave early. Illiquid investments sometimes offer higher returns as a reward for tying money up, but they are unsuitable for money you might need.

Inflation matters because what counts is the real return — the growth after rising prices are taken into account. An investment that grows 4% a year while prices rise 3% has a real return of about 1%. Cash savings that earn less than inflation lose purchasing power every year, which is why long-term money is often invested rather than kept only in cash.

Why it matters

Looking at liquidity and real returns stops you from locking up money you need, and from mistaking nominal growth for real progress.

A real example

The situation

Lior is offered an investment with an attractive yearly return, but money cannot be withdrawn for five years.

What happened

He realises he may need part of the money for a house deposit in three years. He invests only the portion he will not need for at least five years and keeps the rest accessible.

The takeaway

Matching liquidity to his timeline mattered more than chasing the higher return.

How people actually behave

People compare returns in raw numbers and forget both inflation and how hard it will be to get the money out.

Common mistakes

• Locking up money you might need before the lock ends.
• Judging returns without subtracting inflation.
• Keeping decades-away money entirely in cash earning below inflation.

Questions to think about

• Which of your money might you need suddenly, and is it easy to reach?
• Is any of your long-term money losing value to inflation?

Try it: Real return check

1. Find what one of your savings or investments earned last year.
2. Subtract last year’s inflation rate in your country.
3. Note whether the real return was positive or negative.

Words in this lesson

• Liquidity — How quickly and cheaply something can be turned into money you can spend.
• Real return — The return on money after inflation is taken into account.
• Inflation — The general rise in prices over time, which reduces what each unit of money can buy.
