The lesson in full
To see whether a country's economy is growing or shrinking, people look at GDP: the total value of all goods and services produced in a year.
It adds up spending: households (consumption), businesses (investment), government, plus exports minus imports.
Growth is the % change. India (about 6–8% a year recently) and Indonesia (about 5%) grow faster than rich economies like Germany or Japan, often below 2%.
In 2020 the pandemic shrank the world economy by about 3%, the deepest global recession since the Second World War. Two quarters of shrinking GDP in a row is a common rule of thumb for recession.
Markets react to the surprise: GDP above forecast usually lifts that country's currency and stocks; a miss can sink them.
- Common mistake
Mistake: treating GDP as everyone's income. A country can grow while many people feel poorer. GDP per person, and how growth is shared, matter too.
- Key takeaway
GDP is the size of the economy, and its growth rate is the speed. Markets trade the surprise versus forecast.
Quick check
- GDP measures... The value of everything a country producesIt's the total value of goods and services produced in a period, usually a year or a quarter.
- A common rule of thumb for recession is... Two quarters of shrinking GDPOfficial bodies look at more data, but two falling quarters is the quick test.
- GDP above forecast usually makes that country's currency... StrongerA stronger economy can mean higher interest rates ahead, which attracts money.
- Country A grows 6% a year and country B 1%. This tells you... A's economy is expanding fasterGrowth is speed, not size or wealth. B is still growing, just slowly.
