Ticker	ETF Name	Interest Rate Sensitivity Rationale
VNQ	Vanguard Real Estate	Cap Rate & Financing Costs: High leverage and capital-intensive operations face elevated borrowing costs during yield spikes; dividend yields also compete directly with Treasuries.
XLU	SPDR Utilities	Equity Duration & Yield Competition: High-dividend, defensive sector that acts as a bond proxy; relative appeal declines as risk-free Treasury yields rise.
XHB	SPDR S&P Homebuilders	Mortgage Rate Transmission: Directly impacted by 30-year mortgage rates driven by 10-year yields, affecting home buyer affordability and new construction demand.
IWM	iShares Small-Cap Russell 2000	Financing Costs & Credit Conditions: Small-cap companies tend to rely more heavily on bank lending and external financing than large-cap firms, making earnings and valuations especially sensitive to interest rates, credit spreads, and lending conditions.
KRE	SPDR S&P Regional Banking	Yield Curve & Net Interest Margin (NIM): Direct exposure to short/long spread dynamics; benefits from curve steepening but vulnerable to yield curve inversion and deposit beta.
PFF	iShares Preferred & Income Securities	Hybrid/Fixed Income Substitute: Preferred equities carry long/perpetual durations with fixed dividend payouts, trading inversely to benchmark interest rate shifts.
IGV	iShares Expanded Tech-Software Sector	Cash Flow Duration & Discount Rates: High valuation multiples place the bulk of cash flows far into the future, making present value highly sensitive to the discount rate (r).
IYT	iShares Transportation	Indirect/Macro-Cyclical Exposure: Primarily a growth-expectations proxy - rates signal economic trajectory and freight demand rather than acting through duration or leverage. Fleet financing adds a smaller, direct financing-cost channel.
