BANGKOK — Assets of the Thai royal family that have been managed by an official agency have been turned over to direct ownership by the king, who will be able to manage them as he sees fit but must also begin to pay taxes on them, the agency has said.

The wealth of King Maha Vajiralongkorn Bodindradebayavarangkun, including the newly transferred assets, is estimated at more than $30 billion. The transfer of the assets is part of a continuing effort by the 65-year-old king to consolidate his authority since he ascended the throne in 2016.

“All ‘Crown Property Assets’ are to be transferred and revert to the ownership of His Majesty so that they may be administered and managed at His Majesty’s discretion,” said an undated statement posted on the website of the Crown Property Bureau, which had long managed them.
