Zimbabwe's hyperinflation will force President Robert Mugabe from power, the US ambassador to the country has said.
Speaking to a UK newspaper, Christopher Dell predicted that inflation will leap to 1.5m% by the end of the year.
He said political discontent at Mr Mugabe's "disastrous economic policies" meant Zimbabwe was "committing regime change upon itself".
Zimbabwe has 80% unemployment and independent economists say inflation is running at 11,000% per year.
On Thursday, the value of the Zimbabwean dollar plummeted with black market exchange rates reaching 300,000 Zimbabwean dollars to one US dollar. The official rate is 15,000 to one. ....
On Thursday, opposition leader Morgan Tsvangirai made similar predictions of an impending end to Mr Mugabe's rule.
"He's got an economy that's down on its knees, he knows he cannot sustain it," Mr Tsvangirai told the Associated Press.
"He knows he has an army that is jittery. He knows all his popular pillars of support are up against him."
