Zimbabwe has introduced a new gold-backed currency called ZiG – the name stands for “Zimbabwe Gold”.

It is the latest attempt to stabilise an economy that has lurched from crisis to crisis for the past 25 years.
Unveiling the new notes, central bank governor John Mushayavanhu said the ZiG would be structured, and set at a market-determined exchange rate.
The ZiG replaces a Zimbabwean dollar, the RTGS, that had lost three-quarters of its value so far this year.
Annual inflation in March reached 55% – a seven-month high.
Zimbabweans have 21 days to exchange old, inflation-hit notes for the new currency.
However, the US dollar, which accounts for 85% of transactions, will remain legal tender and most people are likely to continue to prefer this.
