After the death of the King in 1718, Psilander belonged to those favoured by the new regime.
He became a Baron in 1719, was suggested as Privy Councillor, and commanded a squadron that blocked the Russian Navy at Gdansk.
Psilander now belonged to the political elite of the country, participating in all Parliaments from 1719 to 1732.
In 1728, he was transferred to the Governorship of Kalmar Län in order to be closer to Karlskrona, the seat of the Swedish Board of Admiralty.
In 1734 he was one of three naval officers proposed to be Naval Privy Counsellor, but the King chose Admiral Edvard Didrik Taube instead, and appointed Psilander president of the Admiralty Board, replacing the promoted Taube.
  Psilander's older brother Johan became Comptroller of the Swedish Navy and was ennobled in 1720 under the name "Psilanderhielm".
