The average person living in Monaco now holds investable wealth of more than USD 20 million, a level that places the principality first in the world on a per capita basis. The figure comes from the 2025 edition of the World’s Wealthiest Cities Report, produced by Henley & Partners with the wealth intelligence firm New World Wealth. At the June 2026 exchange rate of about 1.14 dollars to the euro, that sum converts to roughly EUR 17.5 million, a detail worth keeping attached to the headline, since the number tends to travel without its currency.
For anyone tracking the principality, the interesting question is what such an average actually represents, and how a concentration of capital on this scale shapes the market for the few hundred homes that change hands here each year.
The headline is an average rather than a median. New World Wealth estimates the investable assets of residents, meaning liquid holdings such as listed equities, cash and accessible alternatives, and then divides by a resident population of around 38,000. In a community this small, a relatively modest number of billionaires and centi-millionaires lifts the mean well above what a typical household would recognise as its own position.
The currency is United States dollars, the unit New World Wealth applies across every city it ranks, which is why the euro conversion belongs in any careful reading of the claim. Methodology matters too. The firm tracks more than 150,000 high-net-worth individuals worldwide, with particular attention to those holding USD 100 million or more in listed company stakes. The Monaco estimate sits on top of that database, and it reads as a measure of density rather than of the median resident’s balance sheet.
Monaco holds the highest millionaire density of any city Henley tracks, with the firm putting the share of resident dollar millionaires above 40 percent. On a territory of around two square kilometres, roughly 0.78 square miles, the principality is home to 192 centi-millionaires, each with at least USD 100 million in investable wealth. That is the densest concentration of ultra-wealth anywhere measured, and it explains why Monaco ranks first globally on wealth per capita while sitting well outside the top fifty cities by sheer headcount of millionaires.
The geography sharpens the point. Monaco occupies less ground than New York’s Central Park, yet within those borders it has assembled a resident base whose collective wealth would be conspicuous in a country many times its size. The wider economy moves with the same intensity, and national output recently surpassed ten billion euros.
Several conditions compound. Monaco has levied no personal income tax on its residents since 1869, with the arrangements for French nationals governed by a bilateral treaty. The principality combines that fiscal framework with one of the lowest crime rates in Europe, a stable constitutional monarchy, and a location that puts Nice airport and the wider Riviera within easy reach. For families weighing where to base themselves over the long term, those factors read as durability.
The pull has strengthened as wealth has become more mobile. A record number of high-net-worth individuals relocated across borders in 2025, and Monaco continues to feature among the destinations they consider, a dynamic explored in our look at Monaco’s role as an alternative base for relocating wealth. Tighter residency requirements, which favour larger apartments, have also shifted demand toward the upper end of the market.
This is where the wealth figure meets the property market. Monaco cannot expand outward in any meaningful way, and the supply of new homes arrives in a trickle. According to IMSEE’s Observatoire de l’Immobilier 2025, only 103 private homes were delivered across the principality in 2025, with land reclamation projects such as Mareterra among the few sources of genuinely new stock.
Set that against the demand described above and the pricing follows. The 2025 market recorded 493 transactions worth a combined EUR 5.9 billion. The average price of a new-build sale passed EUR 40 million for the first time, while the estimated price per square metre reached EUR 57,569 across the principality and climbed beyond EUR 70,000 in the Larvotto district. The resale segment set its own record at EUR 3.2 billion, with the average resale reaching EUR 7.6 million and twenty-two individual resales clearing the twenty-million-euro mark, as detailed in our review of the record resale activity across the 2025 market.

Average resident wealth above USD 20 million, 192 centi-millionaires on roughly two square kilometres, and the world’s number one ranking for wealth per capita. The density is the market.
For a prospective buyer, the practical message is that competition for the best assets is intense and largely invisible. The most desirable penthouses and seafront apartments seldom reach a public portal, which raises the value of advance access and rigorous due diligence before any commitment.
For family offices, the data reinforces a familiar allocation logic. Residential property occupies a meaningful share of ultra-high-net-worth portfolios, a pattern Knight Frank’s Wealth Report documents year after year, and Monaco offers one of the rare markets where scarcity provides a structural floor under values. We expand on that thinking in our piece on why real estate still holds such a central place for the wealthy.
The rental market deserves a separate note. New arrivals frequently rent before they buy, partly because a residency application moves more smoothly when housing is already secured, and the same scarcity that drives sale prices keeps prime rents firm. Yields look modest in percentage terms, yet the reliability of demand and the calibre of tenants give the rental segment a particular appeal for owners who value stability over headline returns.
