What Is a Basis Point (bps)?

A basis point is one hundredth of one percent

A basis point, written bps and often said aloud as 'bip' or 'beep', is one hundredth of one percent, or 0.01%. That single rule unlocks everything else: 100 basis points equal 1 percent, 50 basis points equal half a percent, and 25 basis points equal a quarter of a percent.

Because a basis point is so small, it is almost always used in groups. When professional newswires report that a central bank 'raised rates by 25 bps', they mean the policy rate moved up by 0.25 percentage points. When a bond desk says a yield 'fell 8 bps', the yield dropped by 0.08 percentage points. The unit keeps the language tight, which matters when billions of euros reprice on a single number.

You will also hear basis points shortened in speech. 'Up 25 bips', 'a 50 beep move', 'ten bps wider' all describe the same precise unit. Whatever the slang, the arithmetic is fixed: one basis point is always 0.01%.

Why markets talk in basis points, not percent

The reason basis points exist is precision, and the avoidance of a genuinely confusing problem: the difference between a change measured in percent and a change measured as a percent of a percent.

Imagine an interest rate moves from 4% to 5%. Is that a '1 percent' increase or a '25 percent' increase? Both are defensible, and that is the trap. The same move can be described three ways:

• In percentage points: the rate rose 1 percentage point.
• In relative terms: the rate rose 25 percent, because 1 is a quarter of 4.
• In basis points: the rate rose 100 bps, the one reading that cannot be misunderstood.

Basis points to percent: a conversion table

The maths never changes. To turn basis points into a percentage, divide by 100. To turn a percentage into basis points, multiply by 100. The table below covers the values you will meet most often around rate decisions.

A useful habit: whenever you hear a number in bps, mentally slide the decimal two places to the left. '150 bps' becomes '1.50%' instantly, and '8 bps' becomes '0.08%'.

Where basis points show up every day

Basis points are not an academic curiosity. They are the working unit across four corners of the market, and most trading days touch at least one of them.

• Central-bank decisions. Policy changes are announced in bps. A hike of 25 bps is the standard increment, 50 bps signals urgency, and a hold means zero bps. The size of the step, and the surprise versus the forecast, is what moves currencies and indices in the first seconds, and every upcoming meeting is listed on the economic calendar.
• Bond yields. A 10-year yield that 'rose 8 bps' has climbed 0.08 percentage points. Sovereign yields move in bps all day, and even a few bps reprices the cost of government borrowing.
• Loans and mortgages. Retail rates are quoted and compared in bps. A mortgage priced 40 bps above a benchmark, or a lender that trims a rate by 15 bps, is using the same unit as the trading floor.
• Credit and periphery spreads. The gap between two yields is a spread, measured in bps. A periphery bond trading at a spread of 150 bps over the benchmark yields 1.50 percentage points more, a direct read on perceived risk.

Reading a rate decision in basis points

Put it together with a simple scenario. A central bank's policy rate sits at 3.75%. The forecast is a hold, but the actual decision is a hike of 25 bps.

Here is how a trader processes that in order. First, the size: 25 bps is 0.25 percentage points, so the rate moves from 3.75% to 4.00%. Second, the surprise: the market expected no change, so a 25 bps hike is a hawkish shock. Third, the reaction: the currency typically strengthens, rate-sensitive indices often dip, and the relevant sovereign yield can jump several bps within seconds as the market reprices.

Now change one word. If the same bank had delivered 50 bps instead of 25, the surprise doubles and the move is usually sharper. If it had held, the rate change is zero bps and the reaction depends entirely on the tone of the statement rather than the number. The unit is the anchor around which the whole interpretation turns.

Basis point vs percentage point vs pip

Three units get confused constantly. They are not interchangeable, and mixing them up changes the number by orders of magnitude.

The key distinctions: a percentage point is the absolute gap between two percentages (4% to 5% is one percentage point, or 100 bps), while a relative percentage describes proportional change (that same move is a 25% increase). A basis point is simply a convenient one hundredth of a percentage point. A pip, by contrast, belongs to the currency market: it is the smallest standard increment in an exchange rate, usually the fourth decimal place, and it has nothing to do with interest rates. Rates and yields move in bps. Currency quotes move in pips. Keep the two in separate boxes and you will never misread a headline.

Following basis points in real time

Understanding the unit is step one. The edge comes from seeing the number the instant it lands, and reading it against what was expected.

Trading News Terminal is built for exactly that. The Central Banks Tracker presents every policy rate and each change in basis points, so you can see at a glance who hiked, who cut, and by how much. The economic calendar flags upcoming decisions with impact tags (HIGH, MEDIUM, LOW), a live countdown, and the previous, consensus forecast and actual side by side, with the actual auto-injected and colour-coded the moment it crosses the wire. When a central bank surprises the market by 25 bps, you read it in seconds.

On the Pro plan the live news feed delivers headlines the instant they cross from institutional sources, and the hands-free Squawk Box reads them aloud so you never miss a decision while watching your charts. The free Basic plan carries the same feed on a short delay, a generous way to learn the rhythm before you upgrade.

Common questions

bps stands for basis points. One basis point is one hundredth of one percent (0.01%), so 100 bps equal 1 percent. On trading desks it is pronounced 'bips' or 'beeps'.

There are exactly 100 basis points in 1 percent. To convert, multiply any percentage by 100 to get basis points, or divide basis points by 100 to get the percentage. So 0.25% is 25 bps and 1.50% is 150 bps.

Basis points remove ambiguity. Saying a rate rose 'from 4% to 5%' could be read as a 1 percentage point move or a 25 percent relative increase. Describing it as a rise of 100 basis points can only mean one thing, which matters when markets react in seconds.

No. A basis point measures a change in an interest rate, yield or spread and equals 0.01 percentage points. A pip is the smallest standard move in a currency quote, usually the fourth decimal place. Rates move in bps, FX quotes move in pips.

A 25 bps rate hike means a central bank raised its policy rate by 0.25 percentage points, the most common increment. A 50 bps hike is double that, and a hold is a change of zero basis points. You can track every decision and its size on the economic calendar and the Central Banks Tracker.
