Contained and contested: Why Singapore's US tariff risk is smaller than it appears

Key Points

• Singapore faces a 2.5 percentage point tariff adjustment under proposed Section 301 measures, but carve-outs and legal review limit the near-term effective impact.

• The overcapacity investigation is the primary forward risk, as it remains unresolved and could still shift from inquiry to tariff action.

• Singapore’s inclusion in the overcapacity probe is weakened by a USD 3.6 billion US goods trade surplus in 2025, contradicting the surplus-based framing.

• Negotiation pathways through USSFTA and statutory Section 301 requirements create a structured route toward resolution rather than unilateral escalation.

• Structural tailwinds from USD 660 billion AI capex and sustained wealth inflows reinforce Singapore’s positioning despite tariff noise.

A new tariff framework puts Singapore's export sectors in focus

US tariff policy remains a key swing factor for global markets, adding pressure to an already fragile backdrop shaped by elevated geopolitical and trade uncertainty. That pressure returned to the forefront of market attention on 2 June 2026, when the US Trade Representative (USTR) proposed new Section 301 tariffs of 10% or 12.5% on imports from 60 economies over failures to enforce restrictions on goods produced with forced labour. Singapore was placed in the higher 12.5% tariff tier.

Section 301 is widely viewed as the successor framework to Section 122 of the Trade Act of 1974, which currently imposes a 10% tariff on Singapore but expires on 24 July 2026. If implemented as proposed, the new measures would lift Singapore’s effective US tariff rate by 2.5 percentage points, from 10% to 12.5%. Even so, the adjustment remains relatively contained in both magnitude and scope, given carve-outs for energy products, pharmaceutical ingredients, and selected electronics and semiconductors.

The more consequential forward risk sits in a separate Section 301 overcapacity investigation initiated in March 2026. The probe explicitly names Singapore alongside 15 other economies for alleged state-directed excess manufacturing capacity. No tariff proposal has emerged at this stage, and the outcome remains open, ranging from tariffs to a negotiated settlement or no action. This is the channel that defines the potential escalation path and therefore warrants the closest monitoring going forward.

Singapore's mitigating case: grounds for confidence on both fronts

Singapore enters both active Section 301 proceedings — overcapacity and forced labour — from a position that is structurally stronger than the headline risk suggests. The mitigating factors differ across the two probes, but together they form a layered defence that is more robust than what is typically seen among co-investigated economies.

Singapore’s defence in the overcapacity investigation begins with a clear factual inconsistency. The probe was designed to target economies running large goods trade surpluses with the US, and every other economy named in the investigation broadly fits that profile. Singapore does not. The US runs a goods trade surplus with Singapore, not a deficit.

The USTR’s original Federal Register Notice had stated the opposite, attributing a USD 27 billion trade surplus to Singapore. Ministry of Trade and Industry (MTI) disputed the figure immediately, and USTR has since removed it from the official filing. Singapore is therefore the only economy among the 16 named in the investigation where bilateral goods trade flows in the US’s favour. That distinction sits at odds with the investigation’s own evidentiary framework and is now formally reflected in the record before any tariff determination is made.

On the second front, the forced labour investigation that led to the proposed 12.5% tariff, the defence shifts from disputing the factual basis of the probe to arguing Singapore’s structural position within global supply chains. The tariff proposal has been publicly contested by MTI, while the Singapore Business Federation — representing over 34,000 companies across ten trade associations — submitted formal comments to USTR arguing that Singapore’s manufacturing base is demand-driven and commercially oriented, not state-directed. It further highlighted Singapore’s role as a regional hub for multinational firms, where trade restrictions would raise input costs for US corporates embedded in its ecosystem. The July hearing process ensures that no final determination is immediate, preserving a formal window for these arguments to influence the outcome.

The US–Singapore Free Trade Agreement provides the overarching institutional anchor across both proceedings. Under Section 301, USTR is statutorily required to pursue negotiated resolution pathways before imposing tariffs, making settlement through structural commitments or trade adjustments part of the formal process rather than an exceptional outcome. The USSFTA, in force for more than two decades, gives Singapore an established bilateral framework through which such negotiations can take place. Singapore’s open, market-oriented economic model and limited reliance on industrial subsidies also strengthen its position as a credible negotiating counterparty.

Budget 2026 provides the domestic buffer while that process unfolds. A Corporate Income Tax rebate of 50% of tax payable, capped at S$40,000 per company, offers direct cost relief to affected exporters. At the same time, the Double Tax Deduction for Internationalisation scheme, which provides a 200% deduction on eligible overseas expansion expenses, strengthens incentives for market diversification and reduces medium-term reliance on US-bound demand. Together, these measures help cushion near-term earnings pressure while tariff negotiations continue.

Constructive view on Singapore maintained

The tariff proceedings are an external uncertainty being actively managed, not a structural break in Singapore’s growth trajectory. A 2.5 percentage point adjustment on a portion of US-bound exports, still subject to hearings and potential revision, does not alter Singapore’s relative positioning versus regional peers.

Two structural tailwinds anchor the investment case. The first is the AI infrastructure investment cycle. Global technology firms have committed more than USD 660 billion in AI-related capital expenditure for 2026, with Singapore’s electronics and precision engineering clusters embedded directly in that demand pipeline.

The second is capital reallocation driven by geopolitical fragmentation. Persistent US–China competition and trade volatility continue to channel assets toward jurisdictions with regulatory stability and currency credibility. Singapore captures this flow through its financial and insurance sectors, which were among the top contributors to 1Q 2026 GDP growth of 6.0%, reflecting sustained AUM inflows rather than episodic activity.

We therefore remain constructive on Singapore. Tariff noise does not alter the structural growth story, and the policy process underway only strengthens that conclusion. For investors seeking exposure to Singapore’s equity market, we continue to recommend positioning through the Amova Singapore Dividend Equity SGD Fund, the Amova Singapore STI ETF (SGX: G3B), and the  iFAST-Amova Singapore Equity A SGD for broader exposure.
