When Whoosh, Indonesia’s High-Speed Train, Lost Its Momentum — A Financial Time Bomb

In October 2023, Indonesia’s President Joko “Jokowi” Widodo stood beaming aboard the Whoosh, Southeast Asia’s first high-speed train, as it rocketed from Jakarta to Bandung at 350 kilometers per hour. The journey that once took three grueling hours by car now took just 40 minutes. It was a moment of national pride, a technological leap forward, and a symbol of Indonesia’s modernization ambitions.

Two years later, that triumph has soured into what Indonesia’s state railway operator now calls a “ticking time bomb.” The $7.3 billion project is hemorrhaging money, carrying less than half its projected passengers, and generating barely enough revenue to cover its annual interest payments. The Indonesian government is now locked in debt renegotiations with China, desperately seeking a way out of a financial quagmire that threatens to burden taxpayers for decades.

The story of how Indonesia got here is a cautionary tale about infrastructure megaprojects, geopolitical competition, and the hidden costs of seemingly attractive financing deals.

The Bidding War — Japan’s Loss, China’s Victory

The seeds of Indonesia’s predicament were planted a decade ago, when both Japan and China competed fiercely for the lucrative contract to build Indonesia’s first high-speed railway. Japan seemed destined to win. The country had been courting Indonesia since 2008, showcasing its legendary Shinkansen technology and completing detailed feasibility studies by 2014. Japanese trains had operated for decades without a single fatal accident — a sterling safety record that should have been decisive.

Japan’s proposal was financially attractive on paper: approximately $5 billion for the project, with financing at an extraordinarily low 0.1 percent interest rate over 40 years with a 10-year grace period. This was the same concessional rate Japan offered India for its Mumbai–Ahmedabad high-speed rail corridor. For a developing country like Indonesia, access to capital at less than one-tenth of one percent should have been irresistible.

But there was a catch. Japan required the Indonesian government to provide a sovereign guarantee for the loan. This meant that if the project failed financially, the government would be directly responsible for repayment, and the liability would appear on the national balance sheet. For a country already constrained by a constitutional limit of a 3 percent budget deficit, this was politically unpalatable.

In April 2015, China unexpectedly entered the race with a counter-proposal. Initially offering $4 billion with a 25-year loan term at 2 percent interest, China quickly sweetened its bid to $5.5 billion with a 50-year tenure at 2 percent interest. But China’s masterstroke wasn’t the interest rate — it was the financing structure.

China proposed a business-to-business model that required no government guarantee and no Indonesian state budget allocation. The project would be financed through loans to a joint venture consortium between Chinese and Indonesian state-owned enterprises, with the China Development Bank providing 75 percent of the funding. On paper, the Indonesian government would bear zero financial risk.

In September 2015, Indonesia briefly canceled the high-speed rail project altogether, proposing instead a slower, cheaper medium-speed alternative. But China revised its proposal to completely eliminate any fiscal burden on Indonesia — something Japan’s regulations couldn’t accommodate.

Indonesia chose China. Minister Sofyan Djalil explained to Japan’s chief cabinet secretary that “Japan’s business model and regulations have made it impossible [for Indonesia] to give a concession credit to Japanese companies.” Japan’s chief cabinet secretary Yoshihide Suga called the decision “extremely regrettable” and warned, “It defies common wisdom” to undertake such a massive project without government funding. His skepticism would prove prescient.

The Dream Unravels — Why Whoosh Is Failing

The Jakarta–Bandung high-speed railway opened in October 2023 after years of delays and massive cost overruns. The original budget of approximately $6 billion ballooned to $7.3 billion due to land acquisition issues, COVID-19 disruptions, and technical complications. To cover these costs, the China Development Bank extended additional loans worth $560 million — but at a higher interest rate of 3.4 percent rather than the original 2 percent.

The financial mathematics are brutal. The project requires annual interest payments of around $120 million, while projected annual ticket revenue hovers near $110 million. The railway cannot even cover its interest obligations, let alone repay principal or cover operational costs.

The fundamental problem is ridership. The project initially projected 50,000 to 76,000 passengers per day. The reality is far lower: weekday ridership averages 16,000 to 18,000 passengers, with weekends reaching 18,000 to 21,000. Even after expanding service to 62 trips per day and achieving a single-day record of 25,316 passengers, average utilization remains well below the economic threshold.

Accessibility is another issue. Stations are far from city centers — particularly in Bandung, where passengers must take a 20-minute connecting train to reach downtown. Facilities are cramped, and for passengers arriving at Soekarno–Hatta International Airport, reaching the Halim station can take considerable time through Jakarta’s notorious traffic.

Moreover, the 142-kilometer line is too short to maximize its value proposition. The route ends in Bandung rather than extending to other major cities, limiting its utility as a true intercity connector.

The Debt Trap Debate

Operational losses have cascaded through Indonesia’s state-owned enterprise system. PT Kereta Cepat Indonesia China (KCIC), the joint venture operating Whoosh, posted losses of $280 million in 2024 and $107 million in the first half of 2025. The state railway company KAI, which holds a 58.5 percent stake in the parent consortium, absorbed over $200 million in losses, threatening services on other lines.

KAI’s leadership warned lawmakers in August 2025 that the high-speed rail debt had become a “ticking time bomb” requiring urgent restructuring. Total liabilities had reached nearly $7.2 billion by October 2025. Investment Minister Luhut Binsar Pandjaitan confirmed that Indonesia had entered debt renegotiations with China “to avoid default.”

This has reignited accusations of “debt trap diplomacy” — the idea that China uses infrastructure loans under the Belt and Road Initiative to ensnare developing countries in unsustainable debt. Critics point to Sri Lanka’s Hambantota Port, leased to China for 99 years after repayment difficulties, as a cautionary example.

However, the debt trap narrative requires nuance. Studies, including by Chatham House, note that recipient countries often actively seek Chinese financing and structure BRI projects to fit their domestic agendas. In Sri Lanka’s case, the Hambantota lease was not a debt-for-equity swap forced by China but a decision by Sri Lanka to raise foreign reserves.

Similarly, in Indonesia’s case, the Jakarta–Bandung railway was not imposed by China. The government actively pursued the no-guarantee model — a political choice driven by fiscal constraints and Jokowi’s pledge that the project “would not burden state finances.” Yet when state-owned enterprises face insolvency, taxpayers ultimately bear the cost.

Lessons from the Fast Track

Indonesia’s experience with the Whoosh offers several key lessons.

Financing structure matters as much as interest rates. Japan’s 0.1 percent interest was objectively better than China’s 2–3.4 percent, but its requirement for government guarantees made it politically unviable. China’s project-level financing avoided this issue but transferred risk to Indonesian enterprises.

Business viability cannot be wished away. Infrastructure must be economically sustainable, not just technologically advanced. The Whoosh’s problem is not engineering — it’s economics: low ridership, poor station placement, and limited reach. Indonesia’s decision to shift risk away from government finances resulted in a project that prioritizes optics over utility.

Cost overruns are the norm, not the exception. The railway’s cost of $52 million per kilometer is significantly higher than comparable lines in China. Governments must anticipate overruns and avoid optimistic projections.

Geopolitical rivalry can distort decision-making. China “won” the bid, but at the cost of a financially troubled project that now undermines BRI’s reputation. Japan, having “lost,” avoided this burden — a reminder that sometimes losing is the better outcome.

Transparency and accountability are crucial. Lack of transparency in procurement, costs, and financing erodes trust. Future projects must embed openness and clear auditing from inception.

What Happens Next

Indonesia now faces tough choices. Debt renegotiations with China focus on extending repayment periods, lowering interest, or restructuring obligations. The new sovereign wealth fund Danantara may absorb some losses using dividends from state enterprises.

Ironically, President Prabowo Subianto’s administration is also negotiating with China to extend the high-speed rail from Bandung to Surabaya — an additional 700 kilometers costing tens of billions more. The extension could improve ridership and economics, but it could also deepen Indonesia’s debt if projections again prove overly optimistic.

The most likely outcome is a blend of restructuring, capital injections disguised as SOE recapitalizations, and hope that ridership grows as the system matures. The Whoosh will continue to run — abandoning it makes little sense — but the financial weight will ultimately fall on taxpayers, contradicting Jokowi’s original promise.

Other countries are watching. Malaysia under Mahathir Mohamad canceled or renegotiated several major BRI projects in 2018, citing debt concerns, before selectively restarting them under improved terms. His move signaled that developing nations are learning to scrutinize Chinese financing more critically.

The lesson is not that high-speed rail or Chinese funding should be shunned. It is that megaprojects must rest on sound economics, realistic forecasts, and transparent governance. Indonesia’s Whoosh remains a technological triumph — but also a financial warning. Speed, as it turns out, comes at a price, and Indonesia is still learning how to pay it.

If Indonesia Had Chosen Japan’s Offer — The Road Not Taken

If Indonesia could turn back time, the wiser path would have been to prioritize long-term financial sustainability and national accessibility over political symbolism and speed. Accepting Japan’s lower-interest loan, despite its sovereign guarantee requirement, might have resulted in a slower but safer fiscal outcome, given Japan’s proven track record in rail technology, transparent project management, and reliability of execution. Alternatively, Indonesia could have pursued a phased development plan — starting with medium-speed rail and stronger urban integration — to build ridership gradually before committing to high-speed expansion. By valuing economic fundamentals and public utility over the optics of rapid modernization, Indonesia could have avoided a debt-heavy project that dazzled in technology but faltered in viability.
