The Currency Tax: Why the Same Property Returned 137% to One Investor and 42% to Another

MSCI's work on currency risk in property benchmarks produces one of the most uncomfortable charts in real estate. Measured from 2008 to Q2 2020, the MSCI Global Property Fund Index delivered a cumulative total return of 137% in sterling terms, and 42% in both yen and renminbi terms. Nothing about the underlying portfolio changed between those three numbers. A 95-percentage-point spread was created entirely by where the investor happened to bank.

The same analysis shows how much of the ride is FX rather than property. Unhedged annualised volatility ran to 10.8% for a yen-based investor and 9.1% for an Australian dollar investor, against 6.9% for a US dollar investor. Apply quarterly hedging and every one of those figures collapses into a narrow band of roughly 6.1% to 6.4%. In other words, once you strip the currency out, investors in different countries are holding the same risk. Before you strip it out, a Japanese buyer is carrying almost twice the volatility of an American one for identical exposure.

Hedging costs are set by interest-rate differentials under covered interest parity, which means they are largely predictable rather than speculative. MSCI notes that long-run spreads between hedged and local-currency index returns have exceeded 100 basis points a year. That runs in your favour when your home currency carries the lower interest rate and against you when it carries the higher one. The practical consequence: hedging is cheap for a Swiss or Japanese buyer and expensive for a Turkish or Brazilian one, which is precisely the reverse of who needs it most.

Japan is the clearest live example of FX driving a market rather than decorating it. The move in USD/JPY from roughly 110 to 150 handed dollar-based buyers something close to a 27% discount on Japanese property before a single negotiation took place, and the currency traded in the mid-150s entering 2026 and drifted toward 160 by mid-year. Capital responded exactly as you would expect. CBRE recorded a record 6.5 trillion yen of Japanese commercial real estate investment in 2025, up 31% year on year, and Tokyo ranked first globally for direct real estate investment, ahead of both New York and London.

In the central Tokyo wards of Chiyoda, Minato and Shibuya, foreign buyers accounted for 19% of condominium transactions in the first half of 2025. When roughly one in five transactions in a city's prime core is being set by buyers whose purchasing power is a function of the exchange rate, the exchange rate becomes a demand variable. The risk sits on the other side of that trade: the same rate differentials and policy lags that weakened the yen can reverse, and a buyer who underwrote the currency discount as permanent has underwritten the most volatile part of the position as if it were the safest.

The US dollar has fallen roughly 10% against a basket of major currencies since January 2025, touching four-year lows in early 2026, with Morgan Stanley Research projecting a further decline of around 10% by the end of 2026. For non-US buyers this is the mirror image of the Japan trade: US property has become materially cheaper in euro, sterling and yen terms without any repricing of the asset itself. Global direct transaction volumes reached $216 billion in Q1 2026, up 18% year on year, and a meaningful share of that reflects currency-driven repricing rather than a change in fundamentals.

Turkish house prices rose 26.36% in the year to February 2026 in nominal lira terms. Adjusted for inflation, the same prices fell 3.93%. Both numbers are true and they describe opposite outcomes. Turkish households buy property specifically to protect savings from a weakening lira, which sustains nominal demand, but a foreign buyer converting back to a hard currency captures the real number, not the headline. Any market with double-digit inflation should be assessed on real, home-currency-adjusted returns before it is compared with anything else.

The Egyptian pound went from 8.88 to the dollar before the 2016 float to 50.56 by December 2024, a cumulative decline of more than 82%. Egyptian property responded with a real estate price index up around 40% in Q1 2024 following 22% growth the prior year. The trap for foreign capital is subtle: developers selling off-plan on long payment plans priced in expected future devaluation, so the headline price rises were substantially a currency hedge sold to domestic buyers, not value creation available to a dollar investor arriving afterwards.

The pattern generalises. High nominal yields in soft-currency markets are frequently compensation for currency risk rather than evidence of mispricing, and the compensation is often inadequate. The discipline is simple and rarely applied: restate the entire investment case in your own currency, including exit, before comparing it to a hard-currency alternative. A 12% gross yield in a currency depreciating 15% a year is not a high-yield investment.

Through the 2000s, Central European households borrowed in Swiss francs because franc rates were far below local rates. Poland alone accumulated around 550,000 franc-denominated mortgages worth roughly 30 billion euros, equivalent to about 7.7% of Polish GDP. The borrowers earned in zloty and owed in francs, and nobody priced the mismatch because the currency had been stable for years.

When the Swiss National Bank abandoned its exchange-rate cap against the euro in January 2015, the franc jumped roughly 20% against Central European currencies overnight. Across the appreciation cycle, instalments rose by an average of 60% in Hungary and between 50% and 100% in Croatia. The debt had not changed. The currency the debt was denominated in had.

Hungary converted the bulk of its foreign-currency loans into forint at market rates in February 2015, absorbing the problem through legislation before it compounded. Poland did not intervene, and its courts largely held that banks had adequately disclosed the exchange-rate risk, leaving borrowers to carry it. For a cross-border buyer today the lesson is not about Swiss francs. It is that borrowing in a currency you do not earn in converts a property investment into a leveraged currency position, and that position can be called at the worst possible moment.

The most robust hedge available to an individual buyer requires no derivatives at all. Financing a London asset in sterling means the rent and the debt service are denominated in the same currency, so the loan absorbs the FX move rather than amplifying it. Only the equity and the eventual repatriated proceeds carry currency exposure. This natural hedge is available to almost every buyer, costs nothing beyond ordinary borrowing, and removes the failure mode that destroyed Central European households.

Survey work by INREV with Western Sydney University found 71% of institutional real estate investors operate a currency hedging policy. Among them, 52% hedge US dollar exposure, 40% sterling, 28% yen, 28% Australian dollars and 16% euro, while 32% hedge all foreign currency exposure. Forwards are the instrument of choice for 57%. The measured result is a reduction in risk of between 25% and 36% relative to unhedged funds. Institutions are not taking a view on currencies; they are removing an exposure they are not paid to hold.

A portfolio spread across Lisbon, Madrid and Athens is diversified by city and undiversified by currency, because a euro move hits all three simultaneously. Genuine currency diversification means holding across blocs, so that no single central bank decision dominates the portfolio outcome. This matters more as position sizes grow, and it is the cheapest form of hedging available because it requires no counterparty and incurs no forward points.

The UAE dirham has been pegged at 3.6725 to the dollar since 1997 and the Saudi riyal at 3.75 since 1986, with Fitch expecting no change to GCC pegged regimes in the medium term. For a Gulf-based buyer acquiring dollar assets, currency risk is structurally close to zero, and the reverse holds for a dollar buyer in Dubai. Pegged markets deserve an explicit premium in any cross-border comparison, because they deliver the hedged outcome without the hedging cost.

The case against hedging deserves a fair hearing. Hedging locks in a cost that compounds over long holding periods, and property is a long-duration asset that is frequently held for a decade or more. An investor whose home currency is structurally weakening may be better served by unhedged foreign exposure, because the currency loss they are trying to avoid is precisely the loss they are exposed to at home. Hedging also creates cash-flow demands at rollover that can arrive when liquidity is tightest.

Buying into a currency discount assumes the discount persists long enough to matter and does not reverse before exit. Nobody, including institutional treasury desks, forecasts exchange rates reliably over five to ten year horizons. The honest position is that the currency discount available in Japan today is a real reduction in entry cost and an unknown effect on exit proceeds, and those two things should be underwritten separately rather than netted into a single optimistic assumption.

The workable synthesis is to treat currency as a sizing decision rather than a forecasting one. Decide how much of the portfolio may sit outside the home currency bloc, finance locally wherever debt is used, favour pegged or hard-currency markets for the core, and reserve unhedged soft-currency exposure for a deliberately limited satellite allocation. That framework survives being wrong about the direction of any individual exchange rate, which is the only test a currency policy actually has to pass.
