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.
