      "paragraphs": [
        "Treasury Inflation-Protected Securities pay a real yield plus indexation to CPI-U. The principal adjusts upward with inflation; the coupon is paid on the adjusted principal. Holders earn the real yield (locked in at purchase) plus realized inflation. In low-inflation regimes, TIPS underperform nominals (lower real yield); in high-inflation regimes, they outperform.",
        "The mechanism is direct but the volatility is real. TIPS prices move with both real yields and inflation expectations. A 1 percentage point change in real yields can produce 8–15% TIPS price moves, regardless of realized inflation. The asset is not low-volatility despite the 'protection' label."

      "paragraphs": [
        "Breakeven inflation (nominal Treasury yield minus TIPS yield) is the market's implied future inflation. When breakevens are below expected actual inflation, TIPS are cheap; when above, expensive. The signal is symmetric.",
        "The 2021–2023 inflation cycle produced significant breakeven volatility. Breakevens that were 1.5% in early 2020 reached 3% by 2022 and compressed back to 2.3% by 2024. Buying TIPS when breakevens were low (early 2020) produced strong returns; buying when breakevens were elevated (2022) produced weaker outcomes."

      "h2": "The phantom income problem",
      "paragraphs": [
        "TIPS held in taxable accounts produce 'phantom income' — the inflation accrual to principal is taxable annually as ordinary income, even though the holder doesn't receive the cash until maturity or sale. In high-inflation regimes, the phantom income tax can exceed the actual cash coupon, producing net negative cash flow.",
        "The remediation is simple: hold TIPS in tax-advantaged accounts (IRA, 401k, Roth). The phantom income inside these accounts is not taxable. For most retail, TIPS exposure should be concentrated in tax-advantaged wrappers."

      "h2": "I Bonds vs TIPS",
      "paragraphs": [
        "Series I Bonds and TIPS both provide inflation protection but with different mechanics. I Bonds have a 1-year minimum holding period, $10K annual cap, and zero secondary market — they are illiquid but lower-volatility. TIPS trade in liquid secondary markets but carry interest-rate volatility.",
        "For households below the I Bond contribution cap, I Bonds capture the inflation hedge with less volatility. Above the cap, or for tactical positioning, TIPS provide scalable exposure. Many households benefit from both — I Bonds as foundation, TIPS as scaling layer."

  "faqs": [
    {"q": "Are TIPS a good inflation hedge?", "a": "Yes for headline CPI exposure, partial for personal inflation. The hedge is more reliable for retirees with budgets close to CPI weights than for households with idiosyncratic inflation exposure."},
    {"q": "Should I hold TIPS in retirement?", "a": "Yes, often. Retirees face cumulative inflation exposure across long horizons. TIPS or I Bonds provide direct inflation hedge."},
    {"q": "What's the simplest TIPS exposure?", "a": "VTIP (short-duration TIPS), TIP (broad TIPS), or LTPZ (long-duration TIPS) ETFs. Match duration to horizon."},
    {"q": "When are TIPS most valuable?", "a": "Years of unexpectedly high inflation. Anticipated inflation is priced in via breakevens; unanticipated inflation is the unhedged risk."},
    {"q": "Do TIPS work outside the U.S.?", "a": "Yes. UK linkers, Eurozone OATi, and other inflation-linked sovereign markets exist. The dynamics are similar; the inflation indices are local."},
    {"q": "Are TIPS appropriate for emergency funds?", "a": "No — emergency funds need same-day liquidity. Short-duration TIPS funds offer some functionality but with rate-driven NAV variance."}
