Bitcoin vs Bonds: What are the risks?

Comparing Bitcoin ETFs and bonds is all about the balance between return, risk and cost.

Bitcoin’s performance in the past has been marked by volatility and significant returns. Here’s how to:

• Bitcoin’s return in 2024 was 114%. outperforming The major asset classes. The annualized risk is 50% higher compared to bonds and stocks.
• Bonds offer steady income and stability. As an example, by mid-2025 the iShares Treasury Bond ETF (20YT) will be available. offered Vanguard Total Bond Market ETF BND, on the other hand, offered a yield for a period of thirty days that was approximately 4.55%. yield A return of approximately 3.8%. The ETFs give exposure to long-duration Treasurys as well as a mix of investment-grade securities. These are attractive options for income portfolios in periods of increased interest rates and volatility.

The ‘interesting’ thing about the classic 60/40 portfolioThis model, which has been used for decades as a benchmark by institutional investors and retirees, invests 40% in bonds and 60% in equities. However, the prolonged low yields on bonds and inflationary pressures has prompted a call to rethink this model. 

Bitcoin’s value grew in 2022-2023 as interest rates rose. Traditional bond portfolios, however, saw negative returns. Due to this asymmetry, institutions have re-evaluated the return on investment of solely bonds. 

Bitcoin ETFs, as an alternative to fixed income in such portfolios, are being increasingly evaluated. In 2025 alone, US spot Bitcoin ETFs had attracted over $40.6 billion in net inflows through early February, a 175% year-over-year increase Comparing the period of 2024 to that in 2018. 

Meanwhile, May 2025 saw a record $6.35 billion net inflows into BlackRock’s IBIT, its largest-ever monthly haul. These numbers show the increasing popularity of Bitcoin.

Did you Know? A 2024 study ARK Invest’s study with 21Shares showed that a 5% Bitcoin investment in a conventional 60/40-weighted portfolio would increase the annualized return by over 3%. The volatility, however, increased.

ETFs for pension and retirement funds

In retirement and pension portfolios, capital preservation and steady income are usually prioritized over inflation hedges.

By a combination of low inflation rates and prolonged yields, bonds and other stable assets are no longer able to meet these goals. In response, forward-thinking institutions have started to explore small, managed Bitcoin ETF allocations as a way to improve risk-adjusted performance while sticking to their conservative mandates.

Some examples of pension funds are:

• Wisconsin State Investment Board (SWIB): SWIB disclosed an initial $163 million investment in Q1 2024 ($99 million in IBIT and $64 million in GBT). By 2024 it would have increased the IBIT from $321 millions to 6 million share. 
• Michigan State Investment Board Michigan is a prominent holder in the ARK 21Shares Bitcoin ETF. allocation The investment is estimated at $7 million. The investment, though relatively modest in size, reflects an attempt to gain Bitcoin exposure via regulated financial instruments which fit into the compliance parameters for large public funds.
• Houston Firefighters’ Relief and Retirement Fund Houston Firefighters’ Relief and Retirement Fund, one of the early public pension funds that experimented with cryptocurrency allocated Even before ETF approvals, a part of the portfolio was allocated to Bitcoin through New York Digital Investment Group. Although modest, this move was a sign of early acceptance for Bitcoin’s asymmetrical return potential, and its relevance within modern portfolio theories, especially among funds with long-duration liabilities.

Did you Know? The ARK 21Shares Bitcoin (ARKB), which was launched on June 16, 2025. executed A 3-for-1 split of shares is intended to increase accessibility and liquidity, without changing the investment strategy or value of its net assets. The move is a reflection of the growing demand from investors, while Bitcoin’s recent surge above $100,000 has endorsed its rationale.

Tokenized bonds, crypto-backed fixed income and tokenized bonds

There are some alternatives to Bitcoin exchange-traded funds that have gained institutional interest, like tokenized fixed investment. 

This is traditional money market and bond assets, issued in digital form on the blockchain. This innovative product combines institutional assets and blockchain efficiency such as transparency, automated settlements and programmability.

• BlackRock BUIDL funds: In March 2024 the BlackRock USD Institutional Digital Liquidity Fund (BUIDL) The tokenization of US Treasurys, repo contracts, cash and other assets is done on Ethereum platforms, then Solana. Within six weeks, the tokenized fund amassed ~$375 million AUM, quickly surpassing Franklin Templeton’s offering, and grew to over $1.7 billion spread across seven blockchains as of March 2025. One of the unique features is 24/7 trading. Another one is tokenized dividend distributions. 
• Franklin Templeton’s OnChain US Government Money Fund, (FOBXX/BENJI). Fobxx, first introduced using Stellar in 2021, has since expanded its use to include Ethereum, Avalanche Base, Aptos Solana and Solana. It tokenizes US Government securities, money and repos, all under UCITS regulation. More than $594 million AUM by February 2025 With a yield of 4,5%, this is Europe’s first regulated tokenized money-market fund.
• Crypto‑backed yield products: Many platforms are experimenting with crypto‑backed bonds (e.g., Maple Finance, Open Eden), decentralized debt instruments collateralized by digital assets. While still in early stages, their goal is to offer yields on over‑collateralized loans using blockchain-native collateral, previewing a future where digital asset borrowing underwrites fixed-income-like returns.

• Insufficient yield Bitcoin ETFs are not like bonds in that they do no provide a regular income. For income-focused individuals, this may be a deterrent.
• Operational Risk: Institutions may not adopt cryptocurrency due to risks related to accounting standards, ESG issues and the custody of their assets. Bitcoin’s high energy usage, for instance, is a concern for many. ESG-compliant portfolios.

Bitcoin ETFs present a unique opportunity to institutional investors looking for growth and diversification. Although they cannot replace traditional bonds, they do complement them, particularly in an environment of low yield or inflation.

Balanced portfolio management, which includes a small allocation of Bitcoin ETFs can improve performance and manage risk. Institutions must be agile and adapt their strategies as the financial landscape changes. This includes including emerging asset classes such as Bitcoin.
