Schwab Says Just a 1% Crypto Allocation Can Significantly Reshape Portfolio Risk

Charles Schwab's research examines how adding crypto changes the risk profile of a traditional investment portfolio. Because Bitcoin and Ether are far more volatile than stocks and bonds, even a small allocation can amplify overall volatility and weaken existing diversification benefits when markets come under pressure. The allocation percentage therefore warrants more attention than the dollar amount invested.

As of July 20, 2026, the latest report said allocating just 1%–3% of a portfolio to Bitcoin or Ether could materially alter its risk structure and performance under stress. Schwab did not set a specific dollar investment threshold. It classifies crypto as a speculative, high-risk asset and recommends sizing allocations according to individual risk tolerance.
