In a bid to save the Yemeni currency from collapsing, the country's Central Bank suspended any dealing in hard currency.
The move comes after Yemenis started to withdraw their savings from banks in hard currency immediately after the launching of Operation Decisive Storm against Houthis on Thursday.
The central bank gave orders to all banks operating in the country to notify their clients of the inability to withdraw any hard currency.
Last month, the central bank said it has enough foreign cash reserves to import foodstuffs and oil materials needed for local market.
