Czech National Bank study: 1% BTC allocation boosts returns without meaningfully raising portfolio risk.

A study conducted by the Czech National Bank found that allocating just 1% of a model portfolio to Bitcoin increases expected returns without significantly elevating overall risk when measured in Czech koruna, according to Governor Aleš Michl. The finding is notable coming from a central bank — an institution class that has historically kept crypto at arm's length.

The research adds to a growing body of institutional-grade analysis suggesting Bitcoin's low correlation to traditional assets makes it an efficient diversifier even at small weights. For sovereign and pension-scale allocators watching from the sidelines, a central bank's own modelling may carry more persuasive weight than any private-sector pitch.
