Cheese is collateral in Italy, $350 million of it, and a heatwave is eating into the value. Which businesses are built for a warmer world?

🧀 Not gouda: An Italian bank holds over US$350 million in Parmesan as collateral. Heat just pushed its energy bill up 30%.

❄️ Setting the temp: The European suppliers that gain as the continent is forced to adapt. 

💰 Valuing a cool story: How John_Eric weighs up a cooling story against a valuation.

In the hills of Emilia-Romagna, a bank called Credito Emiliano, or Credem, keeps more than half a million wheels of Parmigiano Reggiano in its vaults, worth more than US$350 million. Not as a quirk, as loan collateral, and it has lent against aging cheese since 1953. This summer, Europe's record heat turned that vault into a problem. Holding the wheels at the right temperature pushed the bank's daily energy use up about 30%.

Extreme heat used to be a footnote you skipped in the outlook. Now it lands in hard numbers, energy bills, harvest dates, crop yields, insurance claims, and it creates real winners, the companies selling the world its escape from the heat. But the catch is the more obvious the demand, the more likely the price already reflects it. So the work isn't noticing that heat matters. It's finding where the market hasn't priced it in yet. 

Which company do you think is best built for a warmer world, and is the market already paying for it?
