According to UBS, the global economy's party is well and truly over.
There's been a sharp slowdown in growth following several years of rapid expansion.
And the Swiss banking giant says things are about to get worse.
In short, global growth effectively halved in just one quarter.
The outlook is even worse if US economic strength is stripped out of the equation.
UBS cautions that these are all just estimates.
Still,. the general trajectory doesn't look good.
