the reason why i flagged it is because the main question "Is there a noticeable influence of global inflation on ingame prices?" even if we get the historical ingame market price of tc, which actually was indeed influenced by a global thing (covid), the problem is that we aren't talking about an equal thing as covid anymore but an increase that affects differently to any country, being this a global game it won't impact evenly if were true.
The fact that all game worlds even the most new ones and those from SA are being affected evenly throught this inflation mean that there's something wrong beside the world-wide inflation, people is "controlling" market and that's something that we can prove, meaning that there are some other factor (even more important) that allow player to controll several tons of gold and tc, in this case, in-game inflation.
So that's why im saying whatever answer this question generate is totally opinion based without any proof because the question itself is opinion based and is formulated into an assumption without proofs.
My reco is reworking this question to something that could be proven, like for example "which factor affects the actual state of market"
because if the question were "could the global inflation affect the in-game economy" the answer is "yes but we won't notice it" even if there weren't an in-game inflation, a global inflation must be really strong to impact directly on market and won't impact in the price, will actually impact in the stock, because we aren't trading real goods but in-game time, and in-game time is equally as valuable with or without IRL inflation.
