A 10% risk-free yield? For some, yes.

If the underlying yield opportunity closes or becomes widely unavailable (e.g., through policy change, market normalization, or exhaustion of tax-advantaged capacity), the relative attractiveness of fixed income would shift, potentially redirecting flows back toward equities or other asset classes that had been displaced by the high-yield opportunity.

Continued availability of elevated risk-free yields for specific investor cohorts would likely sustain a bifurcated fixed-income market, with high-earners and tax-advantaged investors capturing outsized returns while broader demand for lower-yielding bonds remains subdued, keeping duration and credit spreads under modest pressure.

If regulatory scrutiny or tax policy changes restrict access to these high-yield instruments or close perceived loopholes, a sudden repricing of affected securities and a sharp reallocation away from those strategies could create localized volatility in municipal bonds, Treasury ETFs, or other tax-sheltered fixed-income categories.
