The Ligue 1 champions will need to sell before they can buy this summer.
European football’s governing body opened an investigation into PSG’s spending, following their splurge last summer.
The French club splashed £200million to land Neymar from Barcelona and also signed Kylian Mbappe on loan from Monaco, with that deal set to be turned permanent for £166million this summer.
La Liga president Javier Tebas accused PSG of “financial doping” while there were suggestions the club had inflated fees for sponsorship deals.
Now the CFCB insist that “after significant fair value adjustments of several club sponsorship contracts” they are happy that PSG are in line with their Financial Fair Play regulations.
“The CFCB Investigatory Chamber further decided to close the investigation into Paris Saint-Germain.
“Such decision follows a detailed review of transfer contracts and an analysis of the related management accounts which confirmed that such transactions were in line with the UEFA Club Licensing & Financial Fair Play Regulations.
“Furthermore, the chamber concluded that after significant fair value adjustments of several club sponsorship contracts – on the basis of evaluations performed by independent third party assessors – the break-even result of the club remains within acceptable deviation for the financial years ending in 2015, 2016 and 2017.
“The financial impact of transfer activities as from the 2017 summer – up to and including the upcoming transfer window – and compliance with the break-even requirement for the 2018 financial year will remain under close scrutiny and will be thoroughly looked at in the coming weeks,” the statement read.
