The United States Department of State has released a report detailing what it says the US has done with more than $12bn in revenue from Venezuelan oil and mineral resources, nearly a year after it abducted the country’s leader, Nicolas Maduro.

The disclosure is part of an effort to “promote transparency and accountability in the management of these funds”, says the 53-page report, released on Thursday.

By the end of September, the State Department report says, nearly all of those funds had been distributed to a set of Venezuelan banks, to be used in foreign exchange interventions, transactions where banks sell those dollars to reduce the amount of local currency floating around and prop up the currency’s value, in this case the Venezuelan bolivar.

The report is heavily redacted and does not provide details about the final recipients of the more than $12bn in funds that was distributed in Venezuela, although it does note that approximately $9.4bn went to “legal entities” and $2.9bn to “individuals”.
