The question of when exactly the *instantiation of Nazi policy* of mass extermination started is debated, but even if you subscribe to the theory that it began after Wannsee, or under the Warthegau in Poland after Barbarossa had started, it’s important to realize that the Nazis didn’t have a term “Holocaust” and many Genocidal actions that we consider to constitute the Holocaust, rather simply, far preceded Barbarossa in the occupied Polish territories.
The Germans at this time had a number of odd ideas about how to deal with the Jews including a rather outlandish plan to ship them all to Madagascar (with full intent that many would die en route). The Holocaust was not completed inked out and planned on September 1st, 1939, but the ideology behind it was alive and active and taking lives before the eastern front opened up by the tens of thousands.
A better statement would be that the scale of the Holocaust was a consequence of Barbarossa, as the Einsatzgruppen mowing down 1.5 million Jews is often less talked about than the Polish camps of Treblinka, Auschwitz and Chelmno, which too coincided with military action in the USSR.
However we Holocaust was not a “consequence” of operation Barbarossa - the scale of it certainly was, but genocidal intent preexisted the operation, and in fact informed the operation.
Christopher Browning in The Origins of the Final Solution: The Evolution of Nazi Jewish Policy, September 1939 – March 1942 (pages 240-241) writes:
“In addition to the practical measures taken to prepare for the war of destruc- tion against the Soviet Union, in particular the formation and training of the Einsatzgruppen, Himmler like so many others reveled in the coming possibilities for demographic engineering that would dwarf the experiments of the previous 18 months. On June 12-15 he met with top ss leaders (including Heydrich and the three future HSSPF for the Russian front: Bach-Zelewski, Prützmann, and Jeckeln) at his renovated Saxon castle in Wewelsburg. According to Bach-Zelewski, Himmler said: "It is a question of existence, thus it will be a racial struggle of pitiless severity, in the course of which 20 to 30 million Slavs and Jews will perish through military actions and crisis of food supply." (Es gehe um eine Existenzfrage, daher werde es zu einem Volkstumskampf von unerbitterlicher Härte kommen, in dessen Verlaufe durch die Kriegshandlungen und die Ernährungs-
schwierigkeiten 20 bis 30 Millionen Slamen und Fuden umkommen würden.)”
We also can see in the Oldenburg Plan written up by Hermann Göring that prior to operation Barbarossa, the intent to killed over 30 million in the east existed. Herbert Backe State Secretary in the Reichs Ministery for Food developed “der Hungerplan” to instantiate this policy.
It’s from these developments and others we can come to the following conclusions:
1. The ideology that produced and motivated the Holocaust preexisted the war in its entirety, and genocidal mass killings started prior to Barbarossa, although not to the infamously huge scale we think of today.
2. The articulation of Nazi policy of genocide was being crafted prior to Barbarossa, and was not a consequence thereof.
3. Operation Barbarossa allowed the Holocaust to develop into the massive scale we think of today, and the Nazi policy further developed during this time.
I will also note, there is an increasingly popular pseudohistorical theory that the Holocaust was driven due to a lack of resources and poor planning for keeping prisoners after Barbarossa began - I do not believe this is what
@souljagoyteller is attempting to say based off of my previous interactions with him, and I don’t want him being confused as saying such based off of this post.

The Holocaust was a consequence of Operation Barbarossa. The idea that a war can’t be genocidal is ludicrous
