Stocks: use a broad global equity UCITS ETF or index fund such as VWCE, IWDA, EUNL or a low-cost MSCI World/ACWI fund.
Long Bonds: use long-duration high-quality government bond exposure. For a euro investor, long-duration EUR government bonds are usually more coherent than unhedged US Treasuries because this sleeve is meant to stabilize purchasing power in the investor’s base currency.
Gold: use physically backed gold ETCs such as SGLD, PHAU or similar products, or physical bullion if storage, insurance and custody risks are understood.
Cash: use Letras del Tesoro, insured deposits, remunerated cash, EUR money-market funds or very short-term EUR cash ETFs such as XEON.
Notas de cuenta: Spanish investors should treat each sleeve as serving a different macro role. Equity exposure can be implemented through UCITS ETFs or eligible fondos de inversion. Fondos may allow tax-deferred transfers, which can help with rebalancing. Gold ETCs generally do not receive the same tax treatment as eligible fondos. Cash may sit outside the broker in deposits or Letras del Tesoro. The long-bond sleeve should not be replaced with generic short-duration bonds, because duration is the intended deflation hedge.
Costes: This portfolio is simple, but each sleeve must be implemented precisely. Long bonds should carry meaningful duration. Gold products should have transparent backing, liquidity and reasonable spreads. Cash should remain liquid and safe rather than being stretched for yield. Avoid replacing cash with risky credit or replacing gold with broad commodities unless intentionally building a different portfolio.
Rebalanceo: Rebalance annually or when any sleeve drifts more than roughly 5 percentage points from target. Because stocks, long bonds and gold can each dominate in different regimes, rebalancing is central to the strategy. Use new contributions first to refill underweight sleeves and reduce taxable sales.
Fiscalidad: Spanish taxation differs across fondos, ETFs, ETCs, Letras, deposits and money-market funds. Eligible fondos may allow tax-deferred transfers, while ETFs and ETCs generally do not. Gold products may have different reporting and tax implications. Interest from deposits, Letras and money-market funds is taxed differently from capital gains. The best implementation may depend more on tax wrapper and rebalancing needs than on tiny TER differences.
