How much does domestic Turkish harvest data actually matter to grain traders?

Researching agricultural data gaps in wheat markets for a project and have a specific question for anyone who trades grains or covers EMEA agricultural supply.

I understand global wheat prices are driven by a complex mix of factors — US crop conditions, Ukrainian/Russian supply, currency moves, geopolitical risk, demand shifts from major importers like China and Egypt. Not asking about any of that.

My specific question is about the Turkish domestic harvest signal specifically.

Turkey is a net wheat importer despite being a large producer. So in theory, when Turkey's domestic harvest comes in significantly above or below expectations, it should affect how much Turkey enters the global market as a buyer — which should matter to anyone trading global wheat flows.

But I genuinely don't know if that signal is large enough to move positions in practice, or if it gets completely swamped by the bigger global variables.

For anyone with real experience in this market:

1. When Turkish domestic harvest surprises — either direction — does it actually change your thinking or positioning?
2. What do you currently use to get supply intelligence on Turkey before official TÜİK statistics are published?
3. Is there a meaningful gap between when you'd want that data and when you can actually get it?

Not pitching anything — genuinely trying to understand whether a local data gap here is real or whether existing sources already cover it well enough.
