The Rules Around the Rules

Singapore has had a free trade agreement with the United States since 2004, one of the longest-standing such arrangements the US has in Asia. Yet more than two decades later, a new 12.5 per cent Section 301 tariff now applies to a range of Singapore goods, affecting roughly one-third of domestic exports to the US, even though important categories including semiconductors, certain electronics, aerospace products, energy and pharmaceuticals remain exempt. 

At first glance, those two facts seem difficult to reconcile. A free trade agreement is meant to reduce barriers and provide businesses with greater certainty, yet companies can still find themselves facing new tariffs and additional restrictions introduced through separate legal and regulatory channels. 

That does not mean the FTA has stopped mattering. It means the architecture around trade has become more complicated. Tariffs negotiated through trade agreements are now only one part of the conditions that determine whether goods, technology and capital can move easily across borders. 

Trade Has Acquired Another Layer 

For decades, the logic of trade liberalisation was relatively straightforward. Countries negotiated lower tariffs, established rules for goods and services, and gave companies clearer terms for entering each other’s markets. 

That framework still exists, but another layer has grown around it. National security, technology controls, supply-chain resilience, labour standards, investment screening and industrial policy increasingly influence how trade is conducted, often through legal authorities that operate alongside traditional FTAs. 

The result is that market access is becoming less binary. A company may benefit from preferential treatment under an FTA and still face additional requirements depending on what it produces, where its inputs come from, which technologies are involved or whether its supply chain attracts regulatory scrutiny. Openness now has less to do with whether a market is open and more to do with what a company has to demonstrate before it can move through it. 

For businesses, that makes compliance part of competitiveness. Knowing where a product was assembled may no longer be enough. Companies increasingly need visibility further back along their supply chains, covering origin, ownership, labour practices, technology exposure, and sometimes the identities of customers or counterparties. 

The Election Changes Less Than It Seems 

The US midterm elections on 3 November provide an obvious reason to revisit the relationship, but the result itself may matter less than the broader policy direction around it. 

A divided Congress could slow parts of the domestic legislative agenda and increase oversight of the administration, but it would not necessarily reverse trade measures pursued under existing executive authorities. A Republican hold would likely mean more continuity in the current use of tariffs, national security reviews, and regulatory pressure as tools of economic policy. 

The instruments and emphasis may differ depending on who controls Congress and the administration, but a more interventionist approach to trade has become durable within US politics. Economic security, strategic technologies and domestic industrial capacity are now much more closely intertwined with trade policy than they were when many existing FTAs were negotiated. 

For companies, that argues against treating an election as a reset button. The vote may change the politics around trade. It is unlikely to change the direction of travel, and investment, sourcing, and market-entry decisions need to assume that trade policy remains aligned with security and industrial priorities even as the political language around it shifts. 

What Companies Now Have to Prove 

Some of the most consequential trade barriers may no longer look like traditional barriers at all. 

Export controls can determine which technologies may be sold and to whom. Investment-screening regimes can influence who is allowed to own certain assets. Forced-labour and supply-chain rules can require companies to document where inputs originated and how they were produced. Procurement preferences can favour domestic suppliers even when imports remain technically permitted. 

Each requirement may be defensible on its own policy grounds, but together they change the operating environment for companies that trade across borders. Market access increasingly depends not only on price, quality and tariff status, but also on a company’s ability to provide evidence about how its business is organised, which turns supply-chain transparency into a strategic capability rather than a compliance exercise. 

Two companies selling similar products may face very different outcomes if one can document its sourcing, ownership and customers quickly while the other cannot. For investors, that changes what deserves attention too. Regulatory resilience, geographic diversification and supply-chain visibility matter alongside the more familiar measures of revenue growth, margins and market share, particularly for businesses exposed to politically sensitive sectors. 

Singapore Has Leverage, Not Immunity 

Singapore enters this environment from a position of considerable economic relevance. The United States remains its largest source of foreign direct investment, US multinationals are deeply embedded in Singapore’s finance, technology, manufacturing, and regional headquarters ecosystem, and the US runs a large goods trade surplus with Singapore. Those ties give Singapore leverage. They do not make it immune to changes in US policy. 

The practical response has several parts: continuing to press the case for FTA-consistent treatment and targeted exemptions, helping companies meet increasingly demanding supply-chain requirements, and preserving Singapore’s value to American companies as a trusted base for ASEAN. The last of those may matter most going forward. Negotiated rights establish the formal basis of a trading relationship. Economic relevance strengthens the case for those rights to be honoured and expanded through manufacturing capability, financial infrastructure, regional connectivity, and the ability to offer a stable operating base in Southeast Asia. 

Relevance Becomes the Advantage 

The old trade model encouraged companies to ask simple questions. Does a country have an FTA? What tariff applies? What are the rules of origin? Those questions still matter, but they no longer tell the whole story, companies now also need to read technology restrictions, national-security reviews, supply-chain requirements and investment screening as part of the same picture. 

Singapore’s reputation for clear rules, reliable institutions and regional connectivity becomes more valuable precisely because certainty elsewhere is harder to find. The old measure of openness was how few barriers stood at the border. The emerging one is how effectively a business can keep moving through those barriers as the rules around them keep multiplying, and that is the measure Singapore is now being judged against.
