Central Banks

Imagine a DJ at a massive nightclub. The dance floor is the economy. When the DJ speeds up the music, everyone dances faster, spends more at the bar, and the energy builds. When the DJ slows the tempo, the crowd calms down, catches its breath, and the spending eases. The DJ does not control what anyone does. But the DJ controls the rhythm that everyone moves to. That is a central bank. It sets the beat for the entire economy by controlling one thing. The price of money. When a central bank lowers interest rates, borrowing becomes cheap. Businesses expand, consumers spend, and the economy accelerates. When it raises rates, borrowing becomes expensive. Spending slows and the economy cools. Every mortgage payment, every business loan, every credit card bill is influenced by this single decision.
