Indonesia's Current Account Deficit Just Tripled to 3.3% of GDP. Paired With a Widening Budget Deficit, That's a Twin Deficit

In the second quarter of 2026, Indonesia's current account deficit widened to US$12.5 billion, 3.3% of the entire economy, more than triple where it stood three months earlier. Around the same time, the government's own budget deficit kept widening too, on track to hit Rp734.3 trillion by year end. Two deficits, both growing, at the same time, have a specific name in economics: a twin deficit. It is a combination that worries economists more than either gap on its own, because of what it does to the foreign money Indonesia depends on to fund both at once.
A budget deficit is the government spending more than it collects in tax and other revenue. Indonesia covers that gap mainly by selling Surat Berharga Negara (SBN), government bonds, to banks, pension funds and foreign investors.
A current account deficit is the country as a whole paying out more to the rest of the world than it earns, once trade in goods, services, investment income and remittances are all added together. NetWort's earlier post on the difference between the current account and the trade balance walks through exactly what goes into that wider number.
Both gaps get plugged the same way: foreign money flowing in, whether that is a foreign fund buying government bonds or a foreign investor buying Indonesian assets. Economists have watched this specific combination since the 1980s, when the United States ran a large budget deficit and a large current account deficit at the same time, a pattern that has been studied and debated ever since because it makes a country lean on foreign capital from two directions rather than one.
Bank Indonesia's own balance of payments report for the second quarter, published in late August 2026, showed the current account deficit jumping to US$12.5 billion, or 3.3% of GDP (Gross Domestic Product, the total value of everything the economy produces in a quarter). That compares with a revised US$3.6 billion, 1.0% of GDP, in the first quarter, itself a touch narrower than the US$4.0 billion Bank Indonesia originally reported for that quarter back in May, before the usual data revision.
| Measure | Q1 2026 | Q2 2026 |
|---|---|---|
| Current account balance | −US$3.6 billion (revised) | −US$12.5 billion |
| Current account, % of GDP | −1.0% | −3.3% |
| Services account deficit | −US$4.39 billion | −US$5.89 billion |
| Overall balance of payments (NPI) | −US$9.1 billion | −US$0.9 billion |
| Capital and financial account | deficit | +US$12.0 billion surplus |

Bank Indonesia pointed to two things behind the jump: a wider oil and gas trade deficit, tied to elevated global oil prices during the Middle East conflict, and a narrower non-oil trade surplus. The services account, money paid or earned on shipping, tourism and consulting rather than physical goods, also widened, from a US$4.39 billion deficit to a US$5.89 billion one, which alone works out to roughly 17% of the entire quarter-on-quarter widening.
While the current account was widening, the fiscal side of the twin deficit kept moving in the same direction. Through the first half of 2026, government spending outran revenue by Rp196.5 trillion, 0.76% of GDP. Finance Minister Purbaya Yudhi Sadewa told parliament's budget committee in July that the full-year deficit is now projected at Rp734.3 trillion, 2.85% of GDP, still inside Indonesia's 3%-of-GDP legal ceiling but closer to it than originally planned. NetWort's dedicated piece on Indonesia's widening budget deficit and bond yields covers what is driving that number and how it turns into fresh bond issuance.
A budget deficit alone is a domestic financing problem: the government sells bonds, and as long as buyers, foreign or domestic, keep showing up, the mechanics work. A current account deficit alone is a trade-and-income problem: the country needs enough dollars flowing in from somewhere to offset what is flowing out.
Run both simultaneously and the same pool of foreign capital has to cover two separate holes at once instead of one. If global investors turn cautious on emerging markets for any reason, a Fed policy shift, a risk-off swing, a domestic political headline, both the government's bond auctions and the rupiah's stability can come under pressure together, rather than one buffer being able to absorb a shock the other is facing. That is the specific mechanism that makes a twin deficit worth watching more closely than either number in isolation, not a prediction that it will happen.
The twin deficit data landed in the middle of a leadership change at the central bank. Governor Perry Warjiyo resigned on 27 July 2026, reportedly after a policy dispute with Finance Minister Purbaya over liquidity policy, according to Bloomberg and Reuters reporting. Destry Damayanti, who had served as acting governor, was confirmed as Bank Indonesia's new Governor on 27 August 2026.
The day before her confirmation, at her fit-and-proper test before parliament's Commission XI on 26 August, Destry addressed the widening current account deficit directly, pointing specifically to the services deficit as a driver, per CNBC Indonesia and Antara News reporting from that hearing. A new governor taking the seat just as both deficits widen is not itself a risk in numeric terms, but it does mean the market is watching how a new leadership team responds to exactly the pressure this post describes.
None of this points to an imminent currency crisis. Indonesia's foreign exchange reserves stood at US$145.3 billion at the end of July 2026, per Bank Indonesia, enough to cover 5.5 months of imports, comfortably above the 3-month level international standards treat as adequate. The rupiah closed at Rp17,727 per US dollar on 1 September 2026 (JISDOR), and Indonesia's benchmark 10-year government bond yield stood at 7.04% as of 24 August 2026, both levels that already reflect the pressure a widening twin deficit puts on Indonesian assets, rather than a currency in free fall.
What the twin deficit does mean is that the rupiah, bond yields and foreign capital flows are worth watching together rather than one at a time, since a shock to global risk appetite would likely show up in all three at once. NetWort's Macro Context page tracks Bank Indonesia's benchmark rate, the rupiah and the 10-year yield side by side, updated together, so you can see whether they are moving in the calm pattern seen so far or starting to move together under stress.
