In the early morning of November 15, New World developers were notified of a duplication exploit. In response, all forms of wealth transfer are shutting down again until the developers can fix the problem.

Their official statement is as follows

Hello everyone,
We understand that there is a potential duplicate in the forums and social media. We are excluding all forms of transfer of wealth between players (i.e sending currency, guild treasury, trading post, player-to-player trading) pending investigation. Any player who engages in exploiting this exploit will be taken to action.
After investigating the duplication exploit and ready to re-enable wealth transfer, we will update this post.
Thank you for your understanding.
