Money
24 explanations and counting.

When the economy is struggling, central banks can create new money out of nowhere and use it to buy things. It sounds like cheating — here's why they do it and what the catch is.
What is a hedge fund?
Hedge funds are exclusive investment pools for the very wealthy that use clever — and sometimes extremely risky — strategies to make money whether markets go up or down.

Some investors don't want safe bets — they want to find the next big thing before anyone else and put millions behind it. That's venture capital, and it funds the companies that reshape the world.
How does the housing market work?
Why do houses cost so much? Why do prices go up in some places and crash in others? The housing market has its own strange rules — and they affect almost everyone.
What is a trade war?
When two countries start hitting each other's goods with tariffs, prices rise, businesses suffer, and everyone loses a little. That's a trade war — and they're messier than they sound.
What is a tariff?
When countries buy and sell things from each other, governments can slap an extra charge on imported goods. That charge is a tariff — and it ripples through every price you pay.

A credit card lets you spend money you don't currently have. Used well, it's a useful tool. Used carelessly, it's an extremely expensive trap.

A budget isn't just a spreadsheet for boring adults. It's one of the most powerful tools for actually getting what you want in life — at any age.

The economy shrinks, jobs disappear, and everyone feels worse off. Here's what a recession actually is and why they happen.
What is a credit score?
A three-digit number decides whether you can get a mortgage, a phone contract, or a credit card — and most people have no idea how it's calculated.

A pension is money you save during your working life so you can afford to stop working later. The sooner you start, the better — and here's the maths that explains why.
What is insurance?
Insurance is a way of sharing risk with a large group of people so that when something goes wrong, it doesn't completely ruin you financially.
