GDP: The Big Number That Moves Slowly but Shapes Everything
Gross domestic product measures the total value of goods and services an economy produces. It is released quarterly, and it is the broadest gauge of whether an economy is growing or shrinking.
For currency traders, GDP matters less as a trading event than as background. Strong growth tends to support a currency, because it suggests healthy returns on assets and may push the central bank toward higher rates. Weak growth does the opposite.
Most countries publish several estimates of the same quarter. An advance or flash estimate arrives first, followed by revisions as more complete data comes in. Markets react most to the first release, but later revisions can change the story.
The detail inside the number is often more informative than the headline. Consumer spending, business investment, government spending, and net exports tell you where growth comes from. Growth driven by inventory build-up or one-off factors is weaker than growth from consumer demand.
Compare with expectations. A 2.0 percent reading is bullish if the forecast was 1.5, and disappointing if it was 2.5.
Also note the difference between quarter-on-quarter and annualized figures. The United States reports an annualized rate, while many countries report the quarterly change directly, so numbers are not comparable at a glance.
Practical step: look up the last three GDP releases for your pair's economies and note how each pair reacted in the first hour.
