JustChartsWhat Is GDP and How Does It Affect Currencies and Stocks?
GDP (gross domestic product) is the total value of goods and services an economy produces. It is reported quarterly: the US quotes it as an annualised growth rate, while the UK and eurozone usually quote quarter-on-quarter changes. Stronger-than-expected GDP tends to support the currency and stocks; weak GDP raises recession and rate-cut expectations.
Key facts
- GDP formula
- consumption + investment + government spending + net exports
- US release
- advance estimate about a month after the quarter, 8:30 a.m. New York time
- US reporting
- annualised quarterly growth rate
- UK / eurozone
- usually quarter-on-quarter, not annualised
- Recession rule of thumb
- two negative quarters in a row
How GDP is calculated
GDP = consumption + investment + government spending + (exports − imports)
In the US, consumer spending is roughly two-thirds of GDP, which is why consumer data such as retail sales also matter.
Annualised vs quarterly growth
A US GDP figure of “2.0%” usually means the quarter’s growth annualised — about 0.5% actual growth in the quarter. UK and eurozone releases usually quote the raw quarterly change. Comparing them without adjusting is a common mistake.
Advance, second and third estimates
The US Bureau of Economic Analysis publishes an advance estimate about a month after each quarter ends, then revises it twice in the following months. The advance estimate moves markets most; revisions matter when they are large.
How GDP moves markets
| GDP vs forecast | Currency | Stock index | Bond yields |
|---|---|---|---|
| Stronger | Up | Usually up | Up |
| Weaker | Down | Mixed | Down |
GDP describes the past quarter, so markets often react less than to timelier data like PMIs and jobs reports. Look inside the report too: the GDP price index is an inflation measure, and consumer spending shows how strong demand really is.
What is a recession?
A common rule of thumb is two consecutive quarters of negative GDP growth. In the US, the official call is made later by the NBER’s Business Cycle Dating Committee, which looks at a wider range of data.
Frequently asked questions
When is US GDP released?
The advance estimate comes out about four weeks after each quarter ends, at 8:30 a.m. New York time, followed by two revisions.
What does annualised GDP mean?
The quarter’s growth rate expressed as if it continued for a full year — roughly four times the quarterly change.
Does GDP affect forex?
Yes. Surprises change expectations for growth and interest rates, which move the currency — though timelier data often has a bigger effect.
