Italian banks' Parmesan vaults face strain as heat waves raise cooling costs
Italy’s cheese-backed loan system, which stores about $405 million worth of Parmesan in climate-controlled vaults, is under pressure from soaring energy costs caused by extreme heat.
The practice of using Parmesan wheels as loan security dates back to the 1950s and helps Italian dairy producers manage cash flow while their cheese matures for at least a year. Banks store the wheels in high-tech, climate-controlled facilities, where workers and machines regularly brush and turn each wheel as it ages, adding roughly 700 euros of value per wheel. With about half a million wheels in storage, the total collateral value approaches $405 million.
Recent record heat waves have raised the cost of keeping the vaults at the required temperature and humidity, prompting banks like Credito Emiliano to invest in upgraded cooling equipment. The heat also affects the earlier stages of production, as cows expend more energy staying cool, potentially reducing milk output and quality. Experts note the system’s uniqueness and its vulnerability to climate-related energy price spikes.
Why it matters
Rising energy costs from extreme heat threaten a unique financing system that underpins Italy’s multi-billion-dollar Parmesan industry.
