Key Takeaways
  • • Fidelity International says Bitcoin's correlation with the S&P 500 has fluctuated considerably over the past five years, reflecting its sensitivity to macro conditions and investor sentiment.
  • • Fidelity says Bitcoin's correlation with gold has moved between positive and negative territory over five years but has recently strengthened, possibly reflecting interest in the so-called debasement trade.
  • • Giselle Lai, digital assets strategist for Fidelity in Asia Pacific, argues Bitcoin should be assessed on its own merits rather than forced into a single traditional asset class.
  • • Fund selectors face a classification question: whether Bitcoin is a higher-beta growth exposure, a portfolio diversifier or an alternative store of value.
  • • Per Fidelity, Bitcoin gained 6% in September to close at $83,621 after briefly exceeding $86,000, while total crypto market capitalisation rose just over 10% to $3 trillion.
Summary
A research note from Fidelity International argues that Bitcoin may be developing characteristics of both a high-growth risk asset and a store of value, challenging conventional approaches to portfolio construction and asset allocation. Giselle Lai, director and digital assets strategist for Fidelity in Asia Pacific, said Bitcoin's relationship with the S&P 500 has fluctuated considerably over the past five years. Its high volatility and exposure to global liquidity, interest rates and risk appetite have invited comparisons with technology stocks and other higher-beta investments. Bitcoin-specific developments, including anticipation of US spot Bitcoin ETF approvals in late 2023, have at times driven performance independently of equity markets.

Fidelity also presents a digital gold argument. Like gold, Bitcoin has constrained supply, sits outside the traditional fiat monetary system and generates no underlying cash flows, Lai said. Its correlation with gold has moved between positive and negative over five years, but the relationship has recently strengthened. Lai pointed to the debasement trade, in which investors allocate capital to scarce assets amid concerns about fiscal deficits, monetary expansion and the long-term purchasing power of currencies, as one possible explanation. Fidelity said that whether this stronger relationship proves structural or temporary remains an important question to watch.

Fidelity concludes that these competing characteristics make Bitcoin difficult to categorise within conventional portfolio frameworks. For fund selectors, this raises the question of whether Bitcoin should be treated as a higher-beta growth exposure, a potential portfolio diversifier or an alternative store of value.

The analysis comes as digital assets continued to attract investor interest in September despite a challenging macro backdrop. Fidelity noted Bitcoin's 6% monthly gain to $83,621 and Ethereum's 8.4% advance to approximately $2,681. Total cryptocurrency market capitalisation rose just over 10% to $3 trillion. This occurred despite a 25 basis point Federal Reserve rate increase and the US 10-year Treasury yield rising above 5% for the first time since 2007, according to the note.

Lai also cited regulatory developments, including new US Securities and Exchange Commission measures supporting tokenised equities, European Central Bank preparations to invest in tokenised securities, and proposed changes to Singapore's stablecoin framework. Fidelity concludes that Bitcoin's combination of risk-asset sensitivity, technology-driven adoption and gold-like scarcity makes it distinct from conventional investments, and that its role in portfolios may be better understood on its own terms.
