How Singapore spends $100 billion: Tracing the flow of the nation's purse
From a $1.2 billion Budget in 1970 to more than $100 billion today, the Republic's expenditure has grown 83-fold. An interactive look at where every dollar goes — and how the books still balance.
SINGAPORE — When the Finance Minister stands in Parliament each February to deliver the Budget, the headline figure runs to nine zeroes. Behind that single number, however, lies a sprawling redistribution machine: revenue collected from taxes, the Net Investment Returns Contribution and statutory boards, flowing outwards into education, defence, healthcare, transport and dozens of other sectors.
The interactive chart below traces every major flow for a chosen year — from sources of government revenue on the top, through the consolidated Budget in the middle, and out to the ministries and sectors that ultimately spend it. Use the slider, or press play, to see how the picture has shifted between 1997 and 2025.

An 83-fold rise, and the books still balance
Singapore's government expenditure has grown remarkably from just S$1.2 billion in 1970 to over S$100 billion by 2025 — an 83-fold increase. What's striking is that, despite this ballooning Budget, the Republic maintains one of the world's lowest net-debt positions and simultaneously stewards what is, on a per-capita basis, the largest pool of sovereign wealth on the planet.
The unusual approach of running budget surpluses in most years, and investing the proceeds through GIC and Temasek, has built a financial fortress that allows for counter-cyclical spending during crises — including the unprecedented S$100 billion in COVID-19 support packages rolled out between 2020 and 2022.
The Budget is not just an accounting exercise. It is the clearest statement, every year, of what the Government thinks Singapore should become.A senior economist at a local university
What the sectors got
Strip the Budget back to its component parts and a long-running rebalancing becomes visible. Defence, once the single largest line item, has been steadily overtaken by social development — education, healthcare and a fast-rising bill for ageing-related transfers. The chart below tracks the share each major sector has commanded over the past three decades.

Surpluses, deficits and a quiet reserve
The intersection between revenue and expenditure each year reveals the Republic's fiscal health. When revenue exceeds expenditure, the Government records a budget surplus, enabling strategic investments and additions to reserves. When the reverse is true, it results in a budget deficit, requiring careful fiscal management — and, in extreme cases such as 2020, a Presidential nod to draw from past reserves.
Foreign reserves themselves have grown from just S$4.2 billion in 1972 to over S$515 billion by 2025, representing one of the world's largest reserve pools relative to GDP. Managed by the Monetary Authority of Singapore, these reserves serve as a buffer against external shocks and help anchor the Singapore dollar's stability.

The bigger number behind the Budget
The Budget is only the visible portion of a much larger balance sheet. As of 2024, Singapore's total reserves are conservatively estimated at S$2.5 trillion (about US$1.87 trillion), based on publicly available data from GIC, Temasek, MAS and the Central Provident Fund. Many analysts believe the true figure is substantially larger; the Ministry of Finance keeps the full details private to deter currency speculation against the Singdollar.
In other words: the establishment is wealthy. But without prudent fiscal policy, no balance sheet — however large — is safe from mismanagement. The intersection between fiscal discipline and reserve accumulation is, ultimately, what underwrites Singapore's resilience against the next decade of global uncertainty.
