I think we should make a distinction, here.

If you mean the SPSM chakra, then as stated by Ravenlot he hasn't lost it, and the only thing he seemingly lost are the Truth.Seeking Balls.

If you are asking about the Bijuu chakra he used against Madara and Kaguya to:  Make the Magnet Release: Rasengan to seal Marada's Limbo clone Make the Lava Release: Rasenshuriken Freeing himself from the ice with Boil Release chakra Doing the multiple tailed beast rasenshuriken 

That was due to a little bit of chakra that the Bijuus gave him, so he couldn't restore it after using
