What stands behind every Vesper price
Method, administrator, exchange. The chain of trust behind a price you can cite when finance asks where the number came from.
The Method
VPI Methodology
The Vesper Price Index is calculated with input from verified market participants: buyers, sellers, and traders who report their transaction prices. No single participant sees another's data. Inputs are validated, currencies standardized, and outliers excluded before a manipulation-resistant calculation produces a market-representative benchmark.

Euronext Futures
Euronext chose the Vesper Price Index as the settlement reference for its EU Butter and Skimmed Milk Powder futures contracts. A regulated exchange building financial products on top of our benchmark is the clearest external validation of the methodology. This is the first time regulated European dairy futures will use independent price benchmarks.

Frequently Asked Questions
What is EU Benchmark Regulation (BMR)?
EU Benchmark Regulation is the European regulatory framework governing benchmarks used in financial instruments and contracts. It sets requirements for how benchmarks are collected, calculated, and administered. Only benchmarks that comply with BMR can be used as reference rates in regulated financial products.
Which VPI benchmarks are certified under BMR?
Currently, EU Butter and EU Skimmed Milk Powder (SMP) are the financial-grade VPI benchmarks certified under EU Benchmark Regulation. They are administered by Compass Financial Technologies, an authorized benchmark administrator. All other VPI series use the same methodology at commercial grade, without BMR regulatory reporting requirements.
Who is Compass Financial Technologies?
Compass Financial Technologies is an independent benchmark administrator authorized under EU Benchmark Regulation. For the Vesper Price Index, Compass FT receives participant inputs from Vesper and performs the manipulation-resistant calculation. This separation of input collection and calculation is a key part of the methodology's integrity design.
Why did Euronext choose the VPI for their futures contracts?
Euronext selected the VPI as the settlement reference for their EU Butter and SMP futures because it is independently administered, BMR-compliant, and reflects actual transaction prices from across the market. A regulated exchange building financial products on a benchmark is the clearest external validation of the methodology's credibility.
Can I use VPI benchmarks in my contracts?
Yes. Commercial-grade VPI benchmarks are used widely in procurement contracts as independent reference prices. Financial-grade benchmarks (EU Butter, EU SMP) can additionally be used in regulated financial instruments. Both grades reflect the same underlying methodology and data collection standards.
What is the difference between financial-grade and commercial-grade?
Both grades use the same VPI methodology and data collection standards. Financial-grade benchmarks are administered by Compass Financial Technologies under BMR oversight and are required for regulated financial instruments. Commercial-grade benchmarks are administered internally by Vesper using the same process, without BMR regulatory reporting requirements.
