The authorities shut down all exchange stores and imprisoned their owners in the capital Sanaa on Tuesday as the Yemeni rial fell sharply against foreign currencies.
The US dollar hit a record high in years selling for 270YR today.
It rose from 215YR the rate fixed by the power-sharing government in 2012 following the 2011's fluctuating rates.
The GPB was sold for 350YR on Monday up from usual rate of 333YR.
Other main currencies rose as well.
Saudi rial is being sold for 68YR up from the usual rate of 57YR.
The rates approved by the Central Bank of Yemen are as follows, USD for 215YR, GBP for 331YR and Saudi rial for 57YR.
The fall of the national currency comes amid deepening financial owes and other challenges including power vacuum due to the several-months conflict.
In recent months as the conflict including a blockade on all sea, land and air routes continued to affect the national economy, the country's foreign currency reserves dropped from around $4 billion to around $1.7 billion.
The Houthi militant group, which seized power triggering a civil war and a Saudi-led military intervention, has been spending out of the foreign reserves amid a lack of liquidity.
The blockade, part of the Arab military intervention, has affected all imports and exports drying all incomes and leaving no option before the group but the reserves.
