Switzerland’s currency and equity market offer a distinctive blend of stability, policy‑driven asset accumulation, and unique tax considerations that can make them attractive components of a diversified portfolio—provided investors understand the underlying mechanics and potential pitfalls.
Why the Swiss franc (CHF) is considered a safe‑haven currency
- Historical resilience – The CHF has long been viewed as one of the world’s strongest, safest currencies, often likened to “gold” among fiat money.
- SNB balance‑sheet size – The Swiss National Bank (SNB) holds roughly USD 1.1 trillion in assets, of which about USD 1 trillion are foreign‑currency investments (≈ 66 % in government bonds, 11 % in corporate bonds, 23 % in foreign equities).
- Policy to curb appreciation – To prevent excessive CHF strength—which would hurt export‑oriented Swiss industry—the SNB prints franc and sells it on the market, using the proceeds to buy foreign assets (equities, bonds, gold). This creates a large, publicly disclosed foreign‑equity portfolio (≈ USD 230 bn), roughly one‑third of Switzerland’s GDP.
- Risk‑on/off behavior – In “risk‑on” periods the SNB’s equity holdings expose the franc to market upside; in “risk‑off” periods investors flock to the CHF as a safe haven.
Potential downside for the franc
- Currency over‑appreciation – If the SNB cannot contain CHF strength, Swiss exporters could lose competitiveness. Over the past decade the franc has appreciated about 50 % against the euro, forcing firms to rely on innovation and high‑value products to stay viable.
- Limited monetary tools – The SNB’s primary lever is foreign‑exchange intervention; it cannot easily use interest‑rate policy to offset appreciation without jeopardising its price‑stability mandate.
Why invest directly in Swiss equities rather than just holding CHF
- Negative interest rates – CHF deposits and CHF‑denominated bonds typically carry a ‑1 % (or similar) yield, eroding capital over time.
- Equity proxy for a bond‑like return – Selecting Swiss companies with the majority of revenue generated domestically can create a low‑beta, dividend‑paying portfolio that mimics a bond’s risk profile while offering ≈ 5 % annual total return (including dividends).
Building a Swiss‑equity “CHF‑proxy” portfolio
- Screen for domestic revenue exposure – Choose firms whose sales are largely within Switzerland to limit foreign‑currency risk.
- Prioritize low‑beta, high‑quality leaders – Companies with strong brand equity and export‑oriented, high‑value products (e.g., Nestlé, Novartis, Roche) tend to weather CHF appreciation better.
- Consider dividend yield vs. tax drag – Ordinary Swiss dividends are subject to a 35 % withholding tax, the world’s highest. Recovering this tax requires a multi‑step administrative process (broker documentation, tax‑office stamp, submission to Swiss authorities, and a six‑month wait for refund).
Dividend taxation complexities
- Partial credit in home country – For French residents, the 35 % Swiss withholding tax is only partially creditable (≈ 15 %); the remaining 20 % must be reclaimed through a cumbersome procedure.
- Impact on portfolio size – The tax‑recovery effort may be worthwhile only for sizable holdings (e.g., €1 million+), where the absolute amount of reclaimed tax justifies the administrative cost.
Return‑of‑capital (ROC) as a tax‑efficient alternative
- Some Swiss firms distribute return‑of‑capital instead of ordinary dividends. ROC is generally tax‑free in the investor’s home country, bypassing the 35 % Swiss withholding tax.
- Approximately one‑third of Swiss companies use ROC exclusively; others combine ROC with ordinary dividends. Examples:
- Lafarge – 100 % ROC
- Lindt – mix of ordinary dividend and ROC
Concentration risk in the Swiss market
- The Swiss Market Index (SMI) comprises only 20 stocks, with ≈ 60 % of its market cap concentrated in three giants: Nestlé, Roche, and Novartis.
- Diversifying beyond the SMI may require exposure to mid‑cap or small‑cap firms, real‑estate operators, utilities, or telecoms (e.g., Swisscom) that have deeper domestic operations.
Practical considerations for investors
| Issue | Implication | Mitigation |
|---|---|---|
| Negative CHF rates | Holding cash or bonds erodes value | Use dividend‑paying equities or ROC‑focused stocks |
| High withholding tax | Reduces net dividend income | Target ROC‑paying firms or limit exposure to modest dividend amounts |
| Administrative burden | Time‑consuming tax‑recovery process | Reserve for larger portfolios where reclaimed tax outweighs effort |
| Market concentration | Over‑reliance on a few large caps | Add mid‑cap, real‑estate, or utility stocks with strong Swiss revenue |
| Currency appreciation risk | Exporters may suffer | Focus on firms with high‑value, low‑price‑elastic products or those with global diversification |
Summary
Swiss francs provide a robust safe‑haven asset, but the negative interest‑rate environment makes pure currency exposure unattractive for long‑term investors. A carefully constructed portfolio of Swiss equities—preferably those with dominant domestic revenue and a mix of ordinary dividends and return‑of‑capital—can deliver modest, bond‑like returns while preserving exposure to the CHF. Investors must weigh the high withholding tax on ordinary dividends against the administrative effort required for refunds, and be mindful of the market’s concentration in a handful of mega‑caps. For sizable allocations, the tax‑efficiency of ROC and the diversification benefits of mid‑cap Swiss firms become increasingly relevant.
