21Shares has recently adjusted the reference price mechanisms for its four main cryptocurrency exchange-traded products (ETPs). This update involves the 21Shares Bitcoin Core ETP (CBTC), 21Shares Ethereum Core ETP (ETHC), 21Shares Crypto Basket Index ETP (HODL), and 21Shares Short Bitcoin ETP (SBTC).
The changes aim to better align the net asset value (NAV) of each product with the spot market prices. By optimizing pricing inputs, the issuer hopes to reduce discrepancies between fund valuations and the underlying digital assets.
Optimizing Valuation Metrics for Improved Accuracy

The reference price serves as a benchmark for calculating daily NAV and determining creation and redemption values. Accurate NAV calculations help enhance liquidity and facilitate effective arbitrage activities in the secondary market. Inconsistent or illiquid pricing sources may widen premiums or discounts, thereby reducing the appeal to institutional investors. This recalibration marks a step towards more robust pricing methods that reflect the evolving infrastructure of the cryptocurrency market.
Covering Core and Inverse Products
This update applies to the “core” products in the 21Shares lineup as well as more complex strategies. For CBTC and ETHC, the tightened reference pricing aims to reflect the liquidity conditions of major exchanges and provide valuations consistent with the spot market.

The Crypto Basket Index ETP (HODL), which tracks a basket of leading cryptocurrencies, relies on precise pricing to achieve effective monthly rebalancing. Inaccurate reference data could affect the weightings of assets within the basket structure.
The Short Bitcoin ETP (SBTC), as an inverse product, relies on mathematically precise daily reference pricing due to its compounding effects. Daily exercise price errors in inverse products may amplify deviations over time.
This broader update reflects efforts to standardize valuation methods between passive and derivative cryptocurrency investment tools.
