2. Key Takeaways

Tharman Shanmugaratnam (b. 1957) is the ninth and current President of Singapore, inaugurated on 14 September 2023 after winning the presidential election with 70.4% of the vote — the largest margin in the history of the elected presidency. His election was a democratic event of a kind that the Singapore presidency had rarely produced: a genuine contest with a decisive outcome, conferring an unambiguous popular mandate on the winning candidate.
The 2023 presidential election was a three-cornered race. Tharman (70.4%) faced Ng Kok Song (15.7%), a former chief investment officer of GIC, and Tan Kin Lian (13.9%), a former NTUC Income chief executive who had also contested the 2011 election. The margin was not merely comfortable — it was overwhelming, exceeding even Ong Teng Cheong's 58.7% in 1993 and dwarfing Tony Tan's 35.2% in the four-way 2011 contest.
The landslide was remarkable for several reasons. First, Tharman is Indian — a member of a community that constitutes approximately 9% of Singapore's population. His 70.4% meant that he had won support far beyond his own racial community, securing massive Chinese and Malay support in a Chinese-majority nation. This cross-racial mandate was itself a statement about Singapore's multiracial compact: the electorate was willing to select a minority-community president not out of constitutional compulsion (as in the 2017 reserved election) but by free democratic choice.
Second, Tharman was by far the most qualified candidate to hold the elected presidency's custodial powers. As former Finance Minister, Deputy Prime Minister, Chairman of the Monetary Authority of Singapore, and a globally recognised economic policy thinker, he possessed an understanding of Singapore's fiscal architecture that no previous president had matched. If the elected presidency was designed to be a guardian of the reserves, Tharman was the guardian central casting would have produced.
Third, the size of the mandate was widely interpreted as a reaction to the 2017 walkover. Singaporeans who had been denied the opportunity to vote in 2017 turned out in force in 2023, and many cast their ballots with an enthusiasm that reflected pent-up democratic energy. The 70.4% was, in part, a statement that Singaporeans wanted their presidential elections to be real elections — not walkovers, not reserved races, not engineered outcomes, but genuine exercises of democratic choice.
Fourth, the mandate raised a question that the Singapore system has never comfortably answered: what does a president with a 70.4% mandate do with it? The constitutional framework still defines the presidency as a reactive institution — a second key, a custodial guardian, not a leader. But a president with overwhelming popular support is, in political reality, something more than a constitutional watchman. Whether Tharman will use his mandate to push the boundaries of the office — as Ong Teng Cheong did — or will exercise restraint — as Nathan and Tony Tan did — is the central question of his presidency.

3. Presidential Tenure Summary

Tharman's path to the presidency involved a notable transition: he resigned from the PAP and the Cabinet in 2023 to contest the election, formally severing ties with the party he had served for over two decades. Unlike Halimah Yacob's departure from the PAP — which was viewed as cosmetic given that she was the only qualified candidate — Tharman's resignation carried genuine weight. He had been one of the most powerful members of the Cabinet, a potential prime ministerial candidate whose decision not to seek the premiership had itself been a major political event, and a figure whose international stature exceeded that of most Singaporean politicians.

The election campaign was the most substantive in the history of the presidency. Tharman articulated a vision of the presidency that emphasised the custodial function, the role of the president as a unifying figure above party politics, and the importance of maintaining Singapore's fiscal discipline and institutional integrity. His opponents — Ng Kok Song and Tan Kin Lian — were credible but could not match his combination of intellectual authority, policy experience, and public appeal.

The 70.4% result was decisive beyond any precedent. It gave Tharman a mandate that no previous elected president had possessed — stronger than Ong Teng Cheong's, infinitely more legitimate than Nathan's walkovers, and qualitatively different from Halimah's unelected tenure. The mandate was also personal in a way that institutional presidencies rarely are: Singaporeans voted for Tharman because they trusted him specifically — his judgment, his integrity, his competence — not merely because he was the establishment's candidate.

Since taking office, Tharman has adopted a posture of careful dignity — active in ceremonial and community functions, visible as a representative of Singapore on the international stage, but measured in his engagement with the custodial dimension of the office. He has not, as of this writing, publicly challenged the government over the reserves or tested the limits of the presidential powers. Whether this restraint reflects a deliberate strategy, a recognition of institutional constraints, or simply the early caution of a new presidency remains to be seen.

The most significant institutional context for Tharman's presidency is the transition of government from Lee Hsien Loong to Lawrence Wong in May 2024. Tharman presided over the reserves certification for the new government — performing the same function that Wee Kim Wee had performed in 1990, but with vastly greater expertise in the subject matter. Whether this expertise translated into more rigorous scrutiny of the reserves figures is not publicly known.

5. What the Mandate Revealed

The 70.4% revealed several truths about Singapore that the political system has been reluctant to acknowledge.

First, it revealed that Singaporeans, when given the opportunity, will vote with enthusiasm and discernment. The turnout was high, the margin was clear, and the result was unambiguous. The electorate did not need constitutional engineering to produce a good outcome — it needed a good candidate and a real election.

Second, it revealed that racial identity is not the determinative factor in presidential elections that the reserved election mechanism assumed. Tharman — Indian in a Chinese-majority nation — won 70.4% of the vote without the benefit of a reserved election. The electorate chose him on merit, not on race. This result undermined the foundational premise of the reserved election framework: the assumption that minority candidates could not win presidential elections without constitutional protection.

Third, it revealed the accumulated frustration of an electorate that had been denied genuine presidential elections for most of the elected presidency's existence. The three Nathan walkovers, the Halimah walkover, and the narrow Tony Tan victory had all, in different ways, deprived Singaporeans of the democratic experience that the elected presidency was supposed to provide. The 2023 election was, for many voters, the first genuine presidential election they had participated in — and they responded with a mandate of historic proportions.

Fourth, it posed the question that the elected presidency has always struggled to answer: what happens when the mandate is too large? A president with 70.4% has a democratic authority that exceeds, in raw popular terms, the authority of most prime ministers. If Tharman chose to assert the custodial powers — to demand information about the reserves, to challenge government appointments, to hold press conferences about institutional frustrations — he would do so with a popular mandate that would make political retaliation far more costly than it was in Ong Teng Cheong's case. The mandate is, in this sense, both a resource and a test: it gives the president the political capital to act, and it reveals whether the system will allow him to spend it.
