Yes; a couple of years after the Stasi was created, though it was called Kommissariat 5 back then, before the GDR was officially established and could have official agencies.
So, you are claiming that he looked into the future to see what happens with the Stasi?
But even if you want to get technical: He started writing in 1946 and the final manuscript was presented in 1948. The "Volkskommissariat" may have been around, but you really can not compare their activity to the Stasi. If you were talking about them, then your quote makes no sense at all.

No, I'm claiming that from his position (particularly after his involvement in the Spanish Civil War), he was informed of the founding and early activities of the Stasi, and wrote the book based on the thought-experiment "what if a whole country was dominated by these principles?"

That's not surprising, considering how "[i]n reality, K-5 was only nominally housed in the People's Police" (Dennis and Laporte, 2003).
For more about his experience in the Spanish Civil War and its influence on his writing, I suggest the In Our Time episode on Animal Farm: http://www.bbc.co.uk/programmes/b07wgkz4
