Exchange Traded Fund (ETF)

An exchange traded fund (ETF) is an investment fund whose shares trade on a stock exchange like an ordinary equity, giving investors exposure to an underlying asset or index through a brokerage account. SPDR Gold Shares (GLD), launched in 2004, made gold ownable this way, and in January 2024 the United States approved 11 spot bitcoin ETFs, which attracted tens of billions of dollars in their first year.

Why it matters

ETFs change who can own an asset. Retirement accounts, advisors bound by compliance rules, and institutions that cannot hold vault gold or private keys can all buy an ETF ticker. GLD is the historical precedent: it gathered over a billion dollars in days in 2004 and is widely credited with broadening gold demand during the 2000s bull market. The spot bitcoin ETFs repeated the pattern at greater speed, with BlackRock's IBIT reaching tens of billions in assets faster than any ETF in history. The tradeoff is a layer of intermediaries, fund sponsor, custodian, and authorized participants, between the investor and the asset.

In the gold vs bitcoin debate

The ETF is where the two assets now compete most directly, as line items in the same portfolios. Allocators debate splitting the traditional gold allocation with bitcoin, and flows between gold ETFs and bitcoin ETFs are watched as a running scoreboard of preference. Purists on both sides make the same objection, that a share in a trust is not the bearer asset, cannot be withdrawn by ordinary holders, and reintroduces the trusted third parties both assets were designed to escape.
