ETF Evolution: From Index Funds to a $20T Ecosystem
On Zephyr’s Adjusted for Risk podcast, host Ryan Nauman talks with Bob Smith of Sage Advisory and A.J. Harper of InCadense about how ETFs have evolved from early broad index products into a $20T global ecosystem spanning equities, fixed income, commodities, alternatives and more. They discuss why fixed income ETFs have become a core liquidity tool, how ETF innovation has progressed through multiple “generations” (indexes, sectors, smart beta, active/thematic, and now structural shifts), and the role of regulation such as SEC Rule 6c-11 and IOSCO standards in accelerating growth and cross-border access. A.J. explains UCITS ETFs, global distribution advantages, and tax considerations for non-US investors. Bob cautions that leverage and complexity can undermine ETFs’ traditional simplicity, while both highlight tokenization and blockchain as potential upgrades that could enable 24/7 trading, faster settlement, lower frictions, and improved transparency—reinforcing the need for informed financial advice amid expanding choice.
