After six months in circulation, the Reserve Bank of Zimbabwe devalues the country's gold-back currency by 40% in a bid to stabilise the Zimbabwe's economy, bringing it to 24ZiG to $1. The ZiG -- short for Zimbabwe Gold -- officially started trading in April, shortly after it was announced it would replace the Zimbabwean dollar, which has tumbled in value over the past year, pushing inflation through the roof. Zimbabwe President Emmerson Mnangagwa hails the switch as "an important step towards stabilising the domestic currency". IMAGES AND SOUNDBITES
