What are the most valuable assets for a country – gold, silver, currency? In Emilia-Romagna, northern Italy, the answer looks much less traditional. Here, huge climate-controlled warehouses store one of the region’s most unusual forms of wealth: hundreds of thousands of wheels of Parmigiano Reggiano cheese, slowly aging and quietly becoming more valuable over time.To visitors, the buildings look like silent cheese cathedrals. For Italy’s dairy industry, they are a financial lifeline.Parmigiano Reggiano is a strictly controlled cheese. It can be made in a specific region of Italy using only three ingredients: milk, salt, and rennet. Each wheel must be at least 12 months old before being sold. According to CNN, many people are held for 24, 36 or 40 months.However, this long waiting period creates cash problems for producers. Farmers must be paid every month, and feed, labor and energy costs will continue daily. But cheese brings money only much later.To solve this, Credem Bank accepts cheese wheels as collateral for loans.Giancarlo Ravnetti, who manages the bank’s cheese warehouse business, told CNN, “About 4 million wheels of Parmigiano Reggiano are made in Italy, and we keep 500,000… and allow customers to use the wheels as collateral to obtain financing.” He said the system handles “about 2,300,000 wheels per year”, worth “about 325 million euros ($382 million) of Parmigiano Reggiano”.
Inside the Cheese Vault
When the wheels reach the warehouse, they are scanned and recorded in the digital system with details such as production date and origin. Only then are they placed on wooden shelves inside the large storage hall.Conditions in the warehouse are strictly controlled. Temperature, humidity and air flow are controlled. Employees check the wheels every day for cracks or damage.After 12 months, the Parmigiano Reggiano consortium conducts a tapping test, striking each wheel with a hammer to check its quality. Only passing wheels are marked with the official Fire-branded seal.Once approved, the wheels can be used as loan security. The warehouse serves as a guarantee that the cheese is present and in good condition. Ravnetti says the bank has run this system for more than 100 years without losing money.The Parmigiano Reggiano Consortium oversees the entire system. It consists of approximately 300 producers and more than 2,000 dairy farmers. Spokesman Fabrizio Raimondi said it represented a sector of “about 50,000 people” and “more than €4 billion in turnover”. The group checks quality, protects brands and prevents counterfeit products. “These sealers can reassure the consumer that it is genuine and the quality is good,” he says.Most producers work through cooperative societies. Paolo Ganzerli of Grantarre, an Italian cheesemaker, explained that while the system is important, it is also economically challenging. Grantarre is owned by producer cooperatives, so it must pay farmers quickly, even if income from the cheese comes much later.“Without this system of leverage, the world of Parmigiano Reggiano could not exist,” he said.Making cheese is also expensive. Cows must be fed locally grown food, and milk quality varies depending on the region. Costs have increased rapidly in recent years.“The cost of producing feed for cows, the cost of everything, has gone up a lot… Energy, transportation, logistics – everything is more expensive now,” Ganzerly said.
Increasing demand for Italian cheese
In 2025, exports of Parmigiano Reggiano overtook domestic sales for the first time, reaching 50.5% of total worldwide sales.International demand increased by 2.7%. There was an increase of 8.8% in Sweden, 7.8% in the UK and 2.5% in Spain. The United States, the largest export market, rose 2.3% but remains volatile due to new tariffs. “There is regulatory uncertainty and many operators are waiting before placing new orders,” Raimondi said.In Italy, sales are expected to decline 10% in 2025 as higher prices lead people to buy less. However, most families still continue to buy it. Prices rose strongly, with 12-month wheels reaching €13.22/kg and 24-month wheels reaching €15.59/kg. Production also increased to 4.19 million wheels.Ganzerli says the cheese is considered healthy because it is lactose-free, high in protein and has no additives. But he warns that if prices rise too high, people may turn to cheaper cheeses like Grana Padano.Manufacturers typically receive 60-80% of a wheel’s value in advance by using it as collateral. New blockchain systems now also allow cheese stored on farms to be used for credit. The consortium is also trying to boost tourism, aiming to increase visits from 85,000 to 300,000 by 2029.Parmigiano Reggiano is now a €4 billion industry supported by approximately 300 dairies. It depends on tradition, strict rules, and financial systems working together.In silent warehouses, wheels slowly age, turning time and patience into value.
