What are basis points (bps)?

A basis point (bps) is one hundredth of one percent: 0.01%. It's the unit the financial world uses to talk about interest rates and yields precisely. When the Federal Reserve "hikes by 25 basis points," it raised its policy rate by 0.25%. Once you internalize it, half of central-bank news reads faster.

Why not just use percentages?

Because percentages of percentages get confusing. If a rate goes from 4% to 5%, did it rise "1%" or "25%"? Both are arguable. Basis points remove the ambiguity: it rose 100 basis points, full stop. When you're pricing bonds or rate decisions, that precision matters — a misplaced word can mean a huge difference in money.

The quick conversions

• 100 basis points = 1%
• 25 basis points = 0.25% (the classic "quarter-point" move)
• 50 basis points = 0.50% (a "half-point," seen as aggressive)
• 1 basis point = 0.01%

Central banks usually move in 25 bps steps, so a "50 bps" hike or a "75 bps" hike is a signal in itself — it tells you the bank feels urgency.

Why it matters to a forex trader

Rate decisions are the biggest driver of currency value, and they're always quoted in basis points. The market prices expectations in advance: if traders expect 25 bps and the central bank delivers 50, that surprise — the difference between expected and actual basis points — is what moves the currency, often violently.

The takeaway

Basis points are just the market's way of being exact about small numbers. Learn the conversions cold, and central-bank headlines stop being noise: "50 bps and a hawkish tone" instantly tells you the size of the move and the likely direction of the currency.
