Yeah, I’ll own it. You were right about that one, @madeinmyr.
I was still right about Tyrosh dominating the dye trade.
The only thing that could make us happier would be GRRM releasing a Cersei chapter where the Small Council discusses how the Iron Bank’s capital strike is making it impossible to import food.
Westeros is primarily a food exporter, not importer. If you’re looking for a culprit, look to Littlefinger withholding grain from the market, not the Iron Bank withholding capital.
