Bitwise Analyst Says Small Bitcoin Allocations Enhance 60/40 Portfolio Returns with Minimal Volatility Impact

  • Small Bitcoin allocations of 1%-5% significantly boosted returns in a traditional 60/40 portfolio model.
  • Adjusting portfolio structure by increasing short-term bonds further improved returns while reducing volatility.
  • Bitcoin’s low correlation to stocks and bonds makes it a useful diversifier with minimal added risk.

Bitcoin’s volatility has long made traditional investors wary, but new research from Bitwise suggests that small allocations of the asset can actually improve risk-adjusted returns in conventional portfolios.

Matt Hougan, Chief Investment Officer at Bitwise, analysed the performance of 60/40 portfolios – portfolios composed of 60% stocks and 40% bonds – over a seven year period from 2017 to 2024, using Bitwise’s free portfolio simulation tool

He found that adding as little as 1%-5% Bitcoin improved returns significantly. A 5% allocation doubled total returns over the period while barely moving the risk dial – standard deviation increased just 1.2% from 11.34% to 12.54%.

Because Bitcoin has a low correlation to both stocks and bonds, adding it to portfolios has historically boosted returns without significantly increasing risk.

How Portfolio Structure Changes Bitcoins Risk-Return Impact

Hougan also explored how different portfolio structures could influence the risk-return profile when Bitcoin is added. Traditionally investors might reduce both stocks and bonds proportionally to make room for a crypto allocation. But Hougon proposed a different method: managing portfolio risk more deliberately by adjusting other asset exposures.

In one scenario, he rebalanced the portfolio to include 5% Bitcoin while simultaneously increasing the bond allocation by 5% and rotating bond exposure into short-term Treasury bills. This revised structure generated higher returns than a basic 60/40 portfolio while lowering overall volatility.

Even more notably, a fourth portfolio tested by Hougan – with 40% in stocks, 50% in bonds, and 10% in Bitcoin – produced the highest return among all scenarios, while exhibiting less risk than portfolios with lower Bitcoin exposure.

While past performance does not guarantee future outcomes, the analysis suggests that Bitcoin’s role in a portfolio should be considered in context and not in isolation.

When you think about adding bitcoin to a portfolio, don’t do it in isolation. Think about it in the context of your entire risk budget. You might be surprised at the results.

For investors willing to think beyond traditional models, Bitcoin may offer a surprisingly effective way to enhance returns without upending risk tolerance.
