Coinbase and MarketVector Bridge Traditional and Digital With New Store-of-Value Index

MarketVector Indexes and Coinbase Asset Management just launched a fresh benchmark that signals how serious institutions are getting about blending crypto with traditional wealth preservation. The Coinbase Store of Value Index tracks Bitcoin (BTC) and Pax Gold (PAXG)—one of the largest gold-backed tokens on the market—offering investors a single exposure point to both digital and traditional safe-haven assets.

Index Design: Volatility Calls the Shots

Here's what makes this index interesting from a portfolio construction angle: it uses an inverse volatility weighting model. Translation: lower-volatility assets get heavier allocation. The index rebalances quarterly and is calculated as a price-return benchmark denominated in US dollars. Pax Gold, which tracks physical gold prices, currently sits at roughly $2.5 billion in market capitalization, giving the index meaningful liquidity on the traditional commodity side.

MarketVector brings European regulatory credibility to the table—they're an established benchmark administrator that's successfully transitioned from traditional indexing into digital assets. Their track record includes the MarketVector Digital Assets 100 Index and the Coinbase 50 Index, so they understand both ecosystems.

Bitcoin's Store-of-Value Thesis Under Pressure

Here's where the crypto analysis gets thorny. Bitcoin's supposed role as a store of value—the narrative that's anchored crypto bull cases for years—is getting pressure-tested in real time. The launch reflects an evolving definition of "store of value" that now includes both traditional gold and BTC, but the market's sending mixed signals.

Bitcoin has long been pitched as digital gold: strong long-term returns, perceived inflation hedge, all the usual talking points. Except the past year has exposed cracks in that thesis. Bitcoin increasingly trades like a risk asset, moving in lockstep with equities—particularly tech stocks. Grayscale's February research hammered this point home: Bitcoin's behaving more like a growth stock than a safe-haven asset amid ongoing macro uncertainty.

The correlation with US software stocks since early 2024 has been stark. More damaging: gold is outperforming Bitcoin in 2025. Bitcoin peaked above $69,000 in 2021, then topped out around $126,000 last October—less than double the previous cycle high. That's underperformance in the asset class that's supposed to be inflation-protected digital gold.
