Rising rates, a weak rupiah and record foreign investment: how to read Indonesia's quarter if you buy in euros

The signal

Three data points from the same quarter tell a story that looks contradictory when read separately. Bank Indonesia has tightened policy at an unusual pace: roughly 100 basis points in under a month, leaving the BI-Rate at 5.75% after the 17 and 18 June 2026 meeting. The rupiah, even so, trades near 17,960 per dollar and is down close to 10% over twelve months. And foreign direct investment, far from retreating, hit a record in the second quarter: IDR 257.7 trillion, around USD 14.32 billion, up 27.4% year on year.

The simple reading would be "weak currency, country in trouble." The useful reading is different: the central bank is defending the exchange rate with the price of money, productive capital keeps arriving at record levels, and for anyone buying an Indonesian asset with euros, the purchasing power of that currency sits near its strongest level of the past decade.

This article does not say when to buy. It sets out which variables to watch, how they affect the purchase and the operation differently, and which risks do not go away even when the exchange rate is helpful.

What changed in 2026

1. The rate cycle has turned, and quickly

Bank Indonesia had spent several quarters supporting growth. In June 2026 it changed footing. First with an off-cycle hike that took the policy rate to 5.25%, then with a further 25 basis points at the scheduled 17 and 18 June meeting, to 5.75%. The deposit facility was left at 4.75% and the lending facility at 6.50%. The stated aim is twofold: to support rupiah stability and to keep inflation inside the 2.5% band with one point of tolerance, in force for 2026 and 2027.

The calendar matters. The board of governors reconvenes on 21 and 22 July 2026, and market consensus points to another 25 basis points, to 6.00%. Research houses covering Asian currencies expect the cycle to run further: MUFG projects the rate at 6.25% by the end of 2026. More than half of surveyed analysts see at least one additional hike before December.

For a foreign investor, the relevant message is not the exact number but the function: the interest rate is being used as a currency defence tool, not as a response to runaway inflation.

2. The rupiah is weak, but consensus no longer points to further falls

The rupiah has depreciated by roughly 7% so far in 2026 and close to 10% over twelve months against the dollar, trading around 17,960 per dollar on 20 July 2026. Recent pressure has a clear external component: Middle East tension has pushed crude prices higher, which in a net fuel importer translates into fiscal concern and portfolio outflows.

The shift is in the forecasts. Consensus compiled by Bloomberg puts the rupiah near 17,850 per dollar this quarter, and Bank Julius Baer projects 17,800 in the third quarter. The logic is that rate hikes, direct intervention and attractive yields on central bank instruments (SRBI) together slow the depreciation. The ten-year government bond offers close to 7.25%, among the higher yields in emerging markets, and foreign investors have been net buyers for a second consecutive month.

For a euro-based buyer, the practical number is the EUR/IDR cross. Over the past twelve months it has moved in a band from 18,665.9 to 21,001.9 rupiah per euro, with the 2026 high on 9 June at 20,990.4 and the low on 14 March at 19,349.8. In mid-July 2026 the pair traded between 20,480.8 and 20,783.6. In plain terms: a euro buys around 10% more rupiah today than a year ago, but sits below the June peak.

3. Foreign capital has not left: it set a record

This is the data point that breaks the country-under-stress narrative. Foreign direct investment, excluding financial services and oil and gas, rose 27.4% year on year in the second quarter of 2026 to an all-time high of IDR 257.7 trillion, around USD 14.32 billion. That is the strongest growth since the fourth quarter of 2024, and it follows a first quarter already up 8.5%. Across the first half, FDI grew 17.3% to IDR 432.6 trillion, and total investment realisation in the second quarter reached IDR 511.8 trillion.

The source of the money also says something. Over the half year, Singapore leads with USD 8.8 billion, followed by Hong Kong at 7.6, China at 4.9, Japan at 1.9 and the United States at 1.7. The sectors attracting most capital are base metals, other services and mining, which is long-cycle industrial capital rather than hot money.

What it means for the foreign investor

The operational conclusion is that currency and rates affect two distinct moments of a property investment, and they should not be conflated.

At purchase. If capital arrives in euros and the asset is paid in rupiah or at a price indexed to local currency, a weak rupiah increases entry purchasing power. With the pair around 20,500 rupiah per euro against 19,349.8 in March, the difference on a EUR 200,000 outlay is not marginal. That effect is only real, however, if the price is denominated in rupiah. Many developments aimed at international investors are priced in euros or dollars precisely to remove that variable, and in that case the exchange rate delivers no entry discount at all.

In operation. Here the effect partly reverses. Rental income is generated largely in rupiah, and repatriating it to euros with a weak rupiah subtracts. The other side is that the destination gains price competitiveness against more expensive alternatives, which supports foreign demand. Operating costs, labour, maintenance and management are also paid in rupiah, so the margin does not move in the same proportion as gross revenue.

In financing. A BI-Rate heading toward 6.00% or 6.25% makes rupiah-denominated credit more expensive. For a buyer contributing equity in euros, the direct impact is limited. For a developer carrying local debt, it is not. That difference feeds through to the schedule and the final cost of projects that depend on Indonesian financing.

In reading the country. The FDI record is the counterweight to currency weakness. A market attracting industrial investment at record levels while its currency depreciates is going through a relative price adjustment, not a capital flight. These are different situations and should not be conflated when assessing country risk.

The Lombok angle

For a project in Lombok, this macro picture translates into three concrete points, and none of them is a reason to accelerate a decision.

First: price denomination governs everything. Before calculating any currency effect, you need to know whether the contract fixes the amount in euros, dollars or rupiah, and who carries the variation between signing and construction milestone payments. A development priced in euros removes that uncertainty for the buyer and transfers it to the developer, who manages it through local costs.

Second: construction costs are local. Materials, labour and permits are paid in rupiah. A weak currency makes construction cheaper in euro terms, but imported inflation, particularly energy and materials, pulls the other way. The net effect cannot be assumed, it is calculated project by project.

Third: revenue is mixed. The international guest pays in their own currency through the platform, the operation settles in rupiah, and the distribution reaches the investor converted again. That path has friction, and the friction belongs in the model before signing, not after.

Frequently asked questions

Does a weak rupiah make buying a villa cheaper? Only if the price is denominated in rupiah. If the development is priced in euros or dollars, the exchange rate does not change what you pay at entry. What it always changes is the conversion of future income and of local operating costs.

Do Bank Indonesia rate hikes affect my returns? Indirectly. A higher policy rate makes local credit more expensive and can strain the timelines of projects leveraged in rupiah. If your contribution is equity in a hard currency, the impact on your net return comes more through demand and costs than through the interest rate.

Is the rupiah expected to recover? Consensus points to stabilisation, near 17,850 per dollar this quarter and 17,800 in the third according to Julius Baer. These are projections, not certainties. A twelve-month currency forecast carries a wide margin of error and should not be the basis of a property decision.

Should I wait for a better exchange rate before buying? Trying to time the exchange rate is a different bet from investing in a property asset, with a different horizon and risk profile. Currency is a variable in the model, not the reason for the transaction. If the project does not work under a conservative currency scenario, the exchange rate will not fix it.

Risks and caveats

• Currency risk in both directions. The rupiah may keep depreciating or reverse part of the fall. A favourable entry today does not protect future income, which is generated in local currency and converted to euros across the whole life of the asset.
• Rate and cost of capital risk. The tightening cycle could extend beyond the 6.25% projected for end-2026 if currency pressure persists. A higher local cost of money affects leveraged developers and can stretch delivery timelines.
• External macro risk. Recent pressure on the rupiah comes largely from crude prices and geopolitical tension, variables outside the control of Indonesian monetary policy. A fresh energy shock would reverse the stabilisation scenario.
• Projection risk. The exchange rate and interest rate forecasts cited come from research houses and may be revised. No projection in this article should be treated as an expected outcome.
• Operational and market risk. Beyond the macro picture, rental returns depend on occupancy, average daily rate, management and local competition, factors that do not improve because the exchange rate is helpful.
