What does a bank do with my money?

TMC_Using-Money_003

If you’ve read our guide to banking, you’ll hopefully now know that a bank account isn’t just a more convenient and secure version of stashing money under your mattress.

But although we use our bank accounts every day, how a bank actually works can be a bit of a mystery! We’ve pulled back the curtain to find out exactly what’s going on back there…

 

Fee or free?

There are some bank accounts that charge a monthly fee – in return, you might get travel insurance, or cashback, or a better rate of interest. But for most of us, our accounts don’t cost anything up front.

This might seem obvious. After all, it’s your money in there, why should you pay to get at it?! But it hasn’t always been this way – ‘free’ banking only arrived in the UK in the 1970s, and in many other countries it’s common to pay for cash withdrawals or pay a monthly fee.

 

Alright then, what does my account cost the bank?

When you think about it, a bank account is a service the bank provides. And it costs money to provide that service. You might get:

  • Physical, online, mobile and phone banking services. Banks have to develop these – and keep the technology a step ahead of criminals!
  • A debit card with chip and pin and contactless payment technology.
  • Free debit card transactions at many retailers – every time you use this, your bank pays a small fee to the company that accepts the card transaction for the retailer.
  • Free cash withdrawals at their and other banks’ machines – if you withdraw money at another bank’s ATM, your bank pays a small fee to that bank.
  • An interest-free overdraft or credit card – so you can borrow money from them without paying any extra back.

If you use your overdraft and credit card carefully, you could easily never pay the bank anything – despite using those services for years!

 

And where does that money go?

If you’ve got money in your account, it’s not in a box marked Joe Bloggs waiting for you any time you need to take out a tenner.It makes part of a pool of money, along with every other customer’s current or savings account deposits.

Stay with us here, because this bit makes our heads spin: at any given moment, a bank has less money available for withdrawals than the total amount people have deposited. This is because they’ve lent some of it to other people – and are earning money by charging interest on those loans. So if everyone wanted to withdraw all their money in cash at the same time, it would be impossible. That’s called a ‘run on the banks’.

But even if that happens, any savings or current account balance up to £85,000 held with a bank, building society or credit union is protected under the Financial Services Compensation Scheme.

 

So how do they make money?

Let’s face it, no company is going to offer a service like a bank account out of the goodness of their heart. These are some of the main ways banks cover the cost of providing free current accounts:

  • Interest forgone – banks lend a huge amount of money to people, and they don’t have that much just lying around! It’s a lot cheaper for them to use the money you’ve deposited than to borrow it from other banks, so they save money.
  • Interest on lending – although some current accounts do offer interest, it’s less than the interest those banks charge for borrowing using an overdraft, credit card, or loan. So the difference between interest banks pay on deposits and the interest they receive on lending works out as a profit for the bank.
  • Fees and charges – as well as interest, banks might charge daily fees for overdrafts, and charges for exceeding your limit or if you try to make a payment without having enough money in your account.

 

What does this mean for me?

Understanding what a bank does with your cash is helpful if you want to stay on top of your money – it’s more complicated than you might have thought! And it doesn’t just affect your current account: it has a knock-on effect on anything your bank offers, from credit cards to overdrafts.

It also means that even if your account is ‘free’, you need to be careful about the fees you might be charged. Banks can only offer free accounts because of money they make elsewhere, including from charges – so if you’re regularly getting into difficulty, you’re paying for other people’s accounts as well as your own!
