Swiss Capital and Lake Como: The Franc Read

Why Swiss Capital Is Reading Lake Como Through a Currency Lens#

Lake Como is priced in euro, and a Swiss-based principal is not. Every villa listing on the eastern shore, every notarial deed, every mortgage drawn against Italian collateral is denominated in a currency the buyer does not hold day to day. The instrument that sits between the two is the EUR/CHF exchange rate, published daily by the European Central Bank as a reference rate. That fact, not any view on where Lake Como or Zurich goes next, is the subject of this note.

A franc that buys more euro buys a lower headline price in francs for the same lakefront square metre. That mechanical arithmetic is real; that it draws Swiss-domiciled capital toward northern Italy is a Victaura Research assumption, not a measured flow, and this note cites no data on its size. It is not, on its own, a reason to act, and this note treats it as an input to underwriting, not as an argument.

This note does not forecast where the franc goes next, and it does not call Zurich residential property "in a bubble" on its own authority. Both claims belong to institutions with the mandate and the data to make them, cited throughout below. What follows is a reading of published numbers, not a prediction layered on top of them.

What the EUR/CHF Reference Rate Actually Measures#

The EUR/CHF reference rate is the European Central Bank's daily benchmark for how many Swiss francs one euro buys, based on a concertation procedure between central banks across Europe that normally takes place around 14:10 CET, and published around 16:00 CET. It is not a forecast and not a policy target; it is a measured snapshot of where the interbank market cleared that afternoon, published as series EXR/D.CHF.EUR.SP00.A in the ECB's own data. Every figure in the table below is drawn from that single series, so the reading stays internally consistent across eleven years.

A falling EUR/CHF number means the franc has strengthened, because fewer francs are needed to buy one euro. The rate closed 2015 at 1.0835 and stood at 0.9445 on 25 September 2026, a decline of roughly 12.8% over the period, with the move spread unevenly rather than steadily across those years. The mechanics matter more than the direction here: this is the same rate a bank uses to price a hedge, a notary uses to convert a deposit, and an underwriting model uses to translate a euro purchase price into francs. It is one number, doing three jobs.

The rate a principal sees quoted by a private bank or a broker is not identical to the ECB reference rate, and this note is explicit about that gap. Commercial spreads add a margin on top of the reference figure, typically wider for a one-off property transfer than for a repeated institutional flow. The ECB series is the correct benchmark for measuring the trend; it is not the execution price any single buyer will actually receive.

Is Zurich Residential Property in a Bubble?#

UBS says so, in its own index, not this note. The bank's Global Real Estate Bubble Index 2026, published 22 September 2026, scores Zurich at 1.69 points, the highest of the 23 cities it tracks, moving the city from third place in 2025 to first in 2026 and into UBS's own "high risk" category.

The index is built from a basket of ratios, not a single price figure, which is why it reads as a warning rather than a prediction. UBS figures reported by immo!nvest show Zurich property prices up almost 140% over two decades, against rent growth of around 40% and income growth of around 30%, a gap between what an asset costs and what it earns or what its occupants can pay. UBS's 2026 release describes Zurich's price-to-rent ratio as exceptionally high and still rising.

A "high risk" score in a bank's proprietary index is a description of an imbalance, not a forecast of a correction, and this note treats it as exactly that. UBS's own index has flagged elevated risk in various cities for years without a synchronised correction following in all of them; the score names a structural gap between price and income and leaves the timing of any resolution unstated. Reading it as a call to sell Zurich, or to buy anywhere else, would import a conclusion the index itself does not make.

Geneva's Own Risk Reading#

Geneva does not carry Zurich's score, and the index treats the two Swiss cities differently. UBS places Geneva at 1.12 points in the same 2026 index, in the "elevated risk" band one tier below Zurich's "high risk" classification — a real distinction in the bank's own framework, not a rounding difference.

The same low-financing-cost backdrop that UBS names for Zurich shows up in its Geneva commentary too. UBS attributes rising risk in both Swiss cities in part to financing costs that stayed low through the survey period, a Switzerland-wide condition that nonetheless produced two different scores — a reminder that a national interest-rate backdrop and a city-level price imbalance are related measurements, not the same one.

For a principal resident in Geneva rather than Zurich, the practical read is that the two home markets are not interchangeable inputs to a diversification decision. "Elevated" is UBS's word for Geneva, not this note's, and it sits meaningfully below Zurich's "high risk" designation in the same index, published the same day, from the same methodology.

Where Milan — and Como — Sit on the Same Index#

Milan appears in the same UBS index at a materially lower risk tier than either Swiss city, and Lake Como does not appear in it at all. UBS classifies Milan as "moderate risk" in the 2026 edition, alongside Amsterdam, Madrid, Frankfurt and Munich — a category below Geneva's "elevated" and two below Zurich's "high risk." Como is not one of the 23 cities UBS surveys, and the index publishes no score for a lakefront micro-market of this kind.

That omission matters for how the principal should read the index, not just for what it says. UBS's score for Milan describes greater-Milan housing broadly — city-centre apartments, established residential stock — an entirely different segment from a permit-advanced lakefront villa in Pognana Lario. Treating Milan's "moderate" score as a proxy for Como risk would apply an urban-apartment metric to a lakefront asset with its own, thinner, less frequently transacted supply.

What can be said, on Knight Frank's separate prime-market index rather than UBS's, is that Lake Como's own prime segment has a published figure for 2025. Knight Frank's PIRI 100 in The Wealth Report 2026, as reported by IndexBox, records Lake Como prime prices up 6.5% in 2025; this note has not found a comparable published 2025 Knight Frank figure for Milan prime property, so no comparison between the two is drawn here.

How Far Has the Franc Moved Against the Euro?#

The EUR/CHF reference rate has fallen in most years since 2020, and the table below sets out the full decade. The rate closed 2015 at 1.0835 francs per euro and 2025 at 0.9314, a franc that buys noticeably more euro than it did ten years earlier, with two intervening years, 2017 and 2024, when the pair rose before resuming its decline.

The most recent extreme sits in the first quarter of this year. The ECB's reference rate touched 0.9008 on 9 March 2026, its lowest print in this series in a decade, before the pair recovered somewhat through the second and third quarters to reach 0.9445 by 25 September 2026 — still well below every year-end value in the table before 2022.

A single day's low and a single day's current reading are both spot observations, not trends in themselves, which is why the table carries eleven full years alongside them. The direction across the decade is unambiguous; the pace within any given year is not, and the full-year rises of 2017 and 2024 show the rate can move against the multi-year trend for a stretch measured in months, not days.

What a Stronger Franc Changes in a Euro-Priced Villa, and What It Doesn't#

A stronger franc lowers the franc-denominated cost of a euro-priced acquisition, mechanically and immediately, on the day of the wire transfer. A hypothetical villa listed at €5 million would cost a Swiss-domiciled buyer roughly CHF 5.4 million converting at the 2015 year-end rate, and about CHF 4.72 million converting at the 25 September 2026 rate — a difference of close to CHF 700,000 on the same euro price, before any negotiation on the property itself.

What the exchange rate does not change is the property's own value in euro, its planning status, or its operating economics. A permit-advanced lakefront project such as the Modern Villa on Lake Como in Pognana Lario is underwritten in euro — construction costs, regional concessions, comparable transactions — and the currency conversion sits on top of that underwriting as a separate layer, not inside it. A cheaper franc cost does not make the underlying euro asset better or worse; it changes what one specific buyer, converting from one specific currency, pays for the same thing.

The saving is realised in full only if the principal converts back to francs at exit, or never needs to. A buyer who intends to hold the asset, generate euro income from it, or pass it to heirs who will themselves spend euro locks in none of the current currency advantage and needs none of it hedged against a future reconversion. The currency effect described here belongs to the buyer who measures the return in francs, at the point they actually do so — not to the euro-denominated asset itself.

Does the Franc's Strength Cut Only One Way?#

No, and this is where a currency reading has to stop being a sales argument and start being a risk one. A rate that has moved from 1.0835 to 0.9445 over a decade can continue to move, stabilise, or partially retrace over the years a lakefront hold typically runs, and nothing set out above assigns a probability to any of those three paths.

The mechanism that would reverse today's advantage is the same one that created it, run backward. A euro-denominated asset bought cheaply in franc terms in 2026 would cost the same buyer more francs to realise at exit if EUR/CHF simply returned partway toward its 2019 average of 1.1124 by the time of sale — a currency move that would erase part or all of the franc-terms gain described above, independent of what the property itself did over the same period. This is not a forecast that it will; it is the same instrument's arithmetic, applied in the other direction.

How that residual risk is actually priced and, where appropriate, hedged is set out in two companion notes rather than repeated here. The Currency Layer: An FX Underwriting Discipline sets out the discipline of treating a cross-border purchase as two positions, not one; Currency Risk: What Hedging Actually Costs sets out what a forward hedge on a floating pair such as EUR/CHF actually costs to arrange. Both apply directly to a Swiss-domiciled buyer of Lake Como property, and neither is specific to this corridor.

Can a Swiss National Buy Property on Lake Como?#

Yes, subject to a reciprocity test that runs through Switzerland's own restrictions on foreign buyers, not Italy's. Italian law allows a non-EU, non-resident foreign national to acquire real estate only to the extent that an Italian national could acquire equivalent real estate in that foreign national's own country — the principle of reciprocity, applied at the notarial deed and checked by the notary before the transfer can be registered.

Switzerland's own restriction on foreign buyers is the Federal Act on the Acquisition of Real Estate by Persons Abroad of 16 December 1983, known as Lex Koller, and it is that law an Italian notary looks to when a Swiss national wants to buy on Lake Como. Lex Koller makes the acquisition of houses, owner-occupied apartments and building land by persons abroad subject to authorisation, and holiday homes can be authorised only in designated tourist communes of certain cantons, within federal annual quotas. Practitioner guidance treats reciprocity as satisfied for a non-resident Swiss buyer of a secondary or holiday home in Italy with a net living area of up to 200 square metres, and land of up to 1,000 square metres, mirroring the scope Switzerland grants a buyer abroad; Swiss citizens resident in Italy face no such limit, and the Consiglio Nazionale del Notariato has published answers on Swiss cases above the 200 square metre threshold.

This is a legal mechanism, not a tax position, and this note stops at the boundary between the two. A reciprocity finding governs whether the deed can be registered; it says nothing about the Italian and Swiss tax treatment of the purchase, the hold, or the eventual sale, which depends on residency, the structure used to hold the asset, and the bilateral tax treaty between the two states. A Swiss principal should have that tax position confirmed by counsel qualified in both jurisdictions before signing, not inferred from the reciprocity finding described here.

Honestly Disclosed#

This note has limits the principal should weigh before acting on any of it. The EUR/CHF figures here are a snapshot to 25 September 2026 and will have moved by the time this is read; none of the year-end or 2026 values cited should be treated as current without a live quote.

The -15% comparison against the 2019 average is a Victaura Research calculation, not a published index figure, and a different base year would produce a different percentage. 2019 is this note's own choice of base year; choosing 2015 or 2022 as the comparison year instead would produce a materially different number from the same underlying data.

UBS's bubble index and Knight Frank's PIRI index measure different things, on different samples, and this note has not attempted to reconcile them into a single Como-specific score. UBS does not cover Como directly; Knight Frank's Como figure is a prime-segment index, not a bubble-risk measure; treating one as a substitute for the other would misstate what either institution actually found.

The reciprocity and Lex Koller description in this note reflects a legal mechanism as reported by professional and notarial sources, not a personalised legal opinion, and it does not cover the tax consequences of a purchase, which are jurisdiction- and structure-specific. A principal acting on this should verify current cantonal quotas, current Italian reciprocity guidance, and their own tax position with qualified counsel before signing, since all three can change independently of the currency data in this note.

What This Means for the Underwriting#

The practical discipline is to record the exchange rate used on the day of underwriting, and to re-check it before signing, rather than letting a rate glanced at during initial diligence quietly become the assumption the whole deal is priced on. For a Swiss-domiciled principal looking at Lake Como, that means citing the ECB reference rate on the specific date used, not a round number remembered from an earlier conversation.

None of the three institutional findings cited here — UBS on Zurich and Geneva, Knight Frank on Como, the ECB on the exchange rate itself — changes what the property is worth in euro, and none of them is a reason to act on any particular timeline. A permit-advanced lakefront asset is underwritten on its own planning status, construction cost and comparable transactions; the currency and the home-market risk reading sit alongside that underwriting, as inputs a Swiss principal should record, not as a case for or against proceeding.
