The move, announced on January 29, comes after Guaido declared himself interim president last week.
The United States has imposed sanctions on the Venezuelan state oil company PDVSA, a critical source of revenue for the economically crippled country.
On January 29, Venezuela’s attorney general accused Guaido of helping foreign countries to interfere in internal matters and asked the Supreme Court to investigate him.
The court agreed with the request, banning the 35-year-old opposition leader from leaving the country and freezing his bank accounts.
