The closures come despite warnings that now regular business seizures could further spook foreign investors and undermine Chavez's efforts to put state revenues on a solid footing. The nationalisation of eight small- and medium-sized institutions last year prompted fears of a run on the country's banks, as investors moved to withdraw funds. It also sparked a dip in Venezuelan bonds and the country's currency in free trading.
The banking regulator defended Monday's move as a boost to the sector's stability, claiming the three seized banks were facing "serious administrative and managerial problems that resulted in insufficient liquidity to cover their short-term obligations."
The government currently controls around 25 percent of the banking sector, largely due to the purchase of the Banco de Venezuela from the Spain's Santander group in 2009.
