Passive investing is the strategy with the strongest academic and empirical backing for individual investors: it replicates the market rather than trying to beat it. In Spain, accessing this strategy is now easier and more affordable than ever. This guide explains everything from the ground up.
What is passive investing?
Passive investing involves buying and holding funds or ETFs that track a stock index (such as the MSCI World or the S&P 500) rather than paying a manager to select stocks. The reasons for doing so are compelling:
- 90% of active funds fail to beat the index over 15 years, according to the SPIVA report
- Fees 10 times lower: 0.10–0.20% for index funds vs. 1.5–2.5% for active funds
- Automatic diversification: an MSCI World fund invests in 1,500+ companies across 23 countries
- Simplicity: no company analysis, no market timing
The three ways to invest passively in Spain
1. Index funds
Index funds are the most tax-efficient option for Spanish investors, thanks to the tax-free transfer advantage: you can move money between funds without paying taxes, deferring taxes until the final redemption.
Where to buy them:
- MyInvestor: access to Vanguard, iShares, and Amundi funds starting at €1. The best platform for index funds in Spain.
- Indexa Capital: manages a portfolio of index funds for you (starting at a historical 5.40% for a moderate profile)
- Finizens: no minimum investment, diversified portfolio (historical return of 4.50% for moderate profile)
Recommended funds (available on MyInvestor):
- Vanguard Global Stock Index (IE00B03HCZ61): 0.18% annual fee, 1,500+ companies
- Amundi MSCI World (LU1681043599): 0.15% annual fee
- Vanguard Emerging Markets Stock Index: exposure to emerging markets
2. ETFs
ETFs are bought on the stock exchange like stocks, offer greater intraday liquidity and even lower fees (0.07–0.20%), but each sale is subject to tax. They are ideal for tax-advantaged accounts or when you don’t plan to rebalance frequently.
Benchmark ETFs in Europe:
- IWDA (iShares Core MSCI World): fee 0.20%, tracks 1,500+ global stocks
- VWCE (Vanguard FTSE All-World Acc): 0.22% fee, includes emerging markets
- C3M / XEON: Money market ETF, tracks the €STR (~2.00%). Ideal for the conservative component
Where to buy them: Trade Republic (€1/trade), XTB (€0 up to €100,000/month), DEGIRO.
3. Robo-advisors
If you prefer full automation, robo-advisors manage the portfolio for you: they rebalance, automatically contribute, and adjust the risk profile. See our complete comparison of robo-advisors.
The Spanish passive investor’s permanent portfolio
A simple and efficient portfolio for the Spanish investor in 2026:
| Component | Product | Weight | Objective |
|---|---|---|---|
| Global Equities | MSCI World Fund (MyInvestor) | 70–80% | Long-term growth |
| Liquidity / Conservative | Interest-bearing account 2.02% or C3M ETF | 10–20% | Emergency fund + stability |
| Government bonds | 12-month Treasury bills (~2.46%) | 0–10% | Conservative Diversification |
This is not an investment recommendation. Adjust the weights according to your time horizon and risk tolerance.
The role of the conservative component in 2026
With the ECB at 2.00% and 12-month Treasury Bills at ~2.46%, the conservative component of the portfolio no longer “eats into” returns. Options for money you don’t invest in the stock market:
- Maximum liquidity: Revolut 2.27% APR or Trade Republic 2.02% — available the next day
- 6–12-month horizon: Pibank deposit at 2.12% or EVO Banco at 2.85%
- Tax-advantaged: 12-month Treasury Bills (~2.46%) — taxed in the year of maturity
Common mistakes of passive investors
- Over-diversifying: A single MSCI World fund already provides global diversification. You don’t need 10 different funds.
- Checking the portfolio daily: Passive investing works precisely because you don’t react to market noise.
- Trying to time the market: Studies show that DCA (contributing every month, no matter what) outperforms market timing in most periods.
- Forgetting about taxes: In Spain, index funds have a tax advantage over ETFs when switching holdings. This is not insignificant.
- Mixing investing and saving: Your emergency fund (3–6 months of expenses) should be in liquid assets, not in the stock market.
When to start?
The answer is always: now. The effect of compound interest is time-dependent: €10,000 invested today at 6% annually is worth ~€17,900 in 10 years. Waiting 5 years and then investing for 10 years yields ~€13,400. The difference: €4,500 for 5 years of waiting.
You don’t need perfect timing, a perfect portfolio, or a lot of money. You need to start, be consistent, and not panic when the market drops.
