Recessions, explained
What a recession really is, who declares it, and why the market knows before the statistics do.
The definition and its limits
The rule of thumb is two consecutive quarters of falling real GDP. It is useful but imperfect: a shallow six-month dip may not feel like a recession, while a sharp one-quarter crash does.
In practice, official committees look at several indicators together: employment, incomes, production and sales, not just GDP.
Those committees declare a recession months or years after it has begun, because they wait for complete data. The declaration is a historical record, not a warning.
Why markets fall before it arrives
Shares price the future. When investors start expecting lower profits, they sell — even though today's statistics still look fine.
That is why the market usually falls several months before a recession officially begins, and starts recovering while the news is still terrible.
And that is why waiting for "clarity" before investing works out so badly: by the time things become clear, the recovery has already happened.
What happens inside one
Companies cut investment and hiring. Unemployment rises, incomes fall, spending falls, and that cuts company revenues all over again.
The central bank usually cuts rates to break that loop, and the government may raise spending.
Recessions are painful, but also normal — part of the cycle, not a departure from it. Since the Second World War, developed economies have gone through one roughly every ten years.
