Coinbase and MarketVector Debut Hybrid Bitcoin-Gold Store of Value Index

MarketVector Indexes and Coinbase Asset Management have introduced the Coinbase Store of Value Index, a new benchmark designed to track a combination of Bitcoin (BTC) and Pax Gold (PAXG). The index is structured as a price-return benchmark in US dollars, offering investors a standardized way to gain exposure to assets traditionally associated with wealth preservation. The index employs an inverse volatility weighting strategy, meaning assets with lower volatility receive a higher allocation in the portfolio. To maintain this balance, the benchmark undergoes quarterly rebalancing. This methodology aims to stabilize returns by adjusting exposure based on the relative price stability of the two assets. The launch comes amid an ongoing debate regarding Bitcoin's identity as a financial instrument. While long viewed as 'digital gold' and a hedge against inflation, recent data suggests Bitcoin has increasingly behaved like a risk asset, moving in tandem with technology equities. Research from Grayscale Investments in February highlighted this shift, noting that Bitcoin has often mirrored growth stocks during periods of macroeconomic uncertainty. Furthermore, the index arrives as traditional gold has outperformed the leading cryptocurrency throughout 2025. While Bitcoin reached a peak of approximately $126,000 last October—a significant increase from its 2021 high of over $69,000—the rate of return has slowed relative to previous cycles. By combining BTC with tokenized gold, the new index seeks to provide a diversified approach to the evolving definition of a store of value.
