If you priced your grocery bill in Bitcoin instead of dollars, April was a slightly worse month than March. But zoom out a year, and you’re eating significantly cheaper.
That’s the gist of Samara Asset Group’s latest US Bitcoin Consumer Price Index reading, released on June 1. The BTCCPI fell 0.95% month-on-month in April but climbed 25.90% year-on-year, a snapshot that tells two very different stories depending on your time horizon.
What the BTCCPI actually measures
Think of the BTCCPI as the regular Consumer Price Index, but flipped. Instead of asking “how many more dollars does this basket of goods cost,” it asks “how many fewer satoshis does it cost.” When Bitcoin’s price rises faster than consumer prices, the index goes up, meaning your Bitcoin buys more stuff. When Bitcoin stumbles or stalls, the index drops.
Samara launched the index in May 2025, pulling official data from the US Bureau of Labor Statistics and Bitcoin price history from Yahoo Finance. The target audience: corporate treasurers and institutional investors who want a clear, standardized way to evaluate Bitcoin’s purchasing power over time rather than just staring at a price chart.
For context, Bitcoin gained roughly 11% during April alone, closing the month near $75,400. That price appreciation drove most of the BTCCPI’s dynamics, though the traditional CPI’s own movements also factor into the calculation.
Who is Samara Asset Group
Samara is a Malta-based, publicly listed investment firm that has positioned itself squarely in the Bitcoin-native corporate camp. As of May 31, the company held approximately 540 BTC on its balance sheet. The firm also carries the distinction of having issued Europe’s first Bitcoin bond. Samara is actively building financial infrastructure around Bitcoin, and the BTCCPI is part of that broader playbook.
What this means for investors
The BTCCPI isn’t a trading signal. It’s a framing device. The 25.90% year-on-year figure is particularly useful for the “Bitcoin as inflation hedge” argument. Bitcoin’s purchasing power gain of nearly 26% over the same period dramatically outpaces what even the most aggressive fixed-income portfolio could deliver.
The monthly dip of 0.95% highlights Bitcoin’s volatility problem in a treasury context. A corporate treasurer optimizing for quarterly reporting doesn’t love explaining a purchasing power decline in any given month, even if the annual trend is overwhelmingly positive. The index makes this tension visible and quantifiable.
Bitcoin’s April price gain of approximately 11% did most of the heavy lifting, and that introduces a dependency that investors should understand. The BTCCPI is, at its core, highly correlated with Bitcoin’s spot price. When BTC rallies, the index looks great. When it corrects, the index will reflect that pain.
