The Price of Friction
For much of July, markets were trying to decide whether the world was moving into a more manageable phase.
Energy prices had eased from their earlier highs. US inflation had surprised on the downside. AI-related demand was still supporting parts of the manufacturing and export cycle. There was enough in the data to suggest that the global economy might continue expanding without forcing central banks into another round of aggressive tightening.
This week complicated that picture.
The issue is not that growth has suddenly disappeared, or that inflation has returned in full force. The problem is that the global economy is becoming more expensive and less predictable to move through. Shipping routes are being repriced. Tariffs are being raised. Energy and freight risks are returning to the inflation conversation. Labour markets remain too firm for central banks to ignore, while open economies such as Singapore are already responding to the possibility that external cost pressures may intensify.
Inflation does not only come from strong demand. Sometimes, it comes from friction.
The World Is Becoming More Expensive to Move Through
The first sign came from shipping.
Maersk has introduced a USD 1,000-per-container surcharge for cargo on vessels transiting the Strait of Hormuz, even though it is not currently operating services through that route. The move is less about present traffic and more about the cost of uncertainty. Maritime risks in the Middle East have risen following attacks on vessels, the US blockade of Iranian ports and renewed disruption around key shipping corridors.
In normal times, shipping is one of the invisible foundations of global trade. Goods move, contracts are honoured, inventories arrive, and consumers rarely think about the route taken by a container before it reaches a port. That invisibility is disappearing. When the Strait of Hormuz becomes harder to insure, when the Red Sea becomes less reliable, and when alternative land bridge routes also come under threat, the cost does not remain confined to shipping companies. It moves into freight bills, inventory decisions, delivery schedules and ultimately the prices paid by businesses and consumers.
A higher freight premium is not simply a logistics issue. It is a cost added to the movement of goods, affecting energy-sensitive products, manufactured components, consumer goods and the planning assumptions of companies that depend on stable supply chains. The global economy can still function under those conditions. It simply functions with more cost built into the system.
Tariffs Put a Price on Uncertainty
The second source of friction is trade policy.
The United States is preparing to impose new tariffs of 10 to 12.5 per cent on imports from about 60 trading partners. The duties are being introduced on the basis of insufficient action against forced labour imports, and they will replace temporary tariff arrangements across a wide range of goods. Singapore is among the economies facing the higher 12.5 per cent rate, despite arguing that the measure lacks a technical or economic basis given the US trade surplus with Singapore.
The direct impact on any single economy is only part of the story. The larger issue is that tariffs change how companies think about supply chains. Businesses must decide whether to absorb costs, pass them on, reroute production, hold more inventory or delay investment until the policy environment becomes clearer, and none of those choices is cost-free.
Trade uncertainty also has a habit of spreading beyond the goods directly affected. A company may not export heavily to the United States, but its suppliers might. Its customers might. Its components may pass through economies that are affected. Its cost base may rise because competitors, logistics providers or manufacturers begin repricing around a more uncertain trade environment. Tariffs raise the cost of planning even when the first-round exposure looks manageable, and that is precisely why they are harder to price than a simple import duty would suggest.
Why Central Banks Cannot Relax Too Quickly
This matters because central banks are still trying to determine whether inflation is truly under control.
The latest US labour data did not make that task easier. Initial jobless claims fell to 187,000 in the week to 18 July, the lowest level in nearly 60 years and well below expectations. Continuing claims also edged lower, reinforcing the view that the US labour market remains tight.
A tight labour market gives the Federal Reserve less reason to rush. If employment conditions remain firm while tariffs and freight costs threaten to lift inflation expectations, policymakers have room to remain cautious even if some parts of the economy are slowing. The argument for lower rates becomes harder when labour markets continue to signal resilience and new cost pressures are appearing in the background. This is the uncomfortable policy mix now forming, where inflation may not be accelerating sharply but the sources of future inflation risk are becoming more visible. Shipping disruptions can raise goods prices. Tariffs can increase import costs. Energy risks can return quickly if geopolitical conditions worsen. At the same time, strong labour markets can keep wage pressure alive and reduce the urgency for central banks to support growth.
For markets, this means the path to easier policy is not only about softer inflation prints. It also depends on whether the global economy can avoid another round of cost shocks.
Singapore Feels the Friction First
Singapore is a useful place to understand why this matters.
Private home prices rose just 0.5 per cent quarter-on-quarter in the second quarter, the slowest increase since the third quarter of 2024. On its own, that points to softer property momentum and a less heated domestic environment. Yet headline inflation rose to 1.9 per cent in June, the highest since September 2024, with cost pressures coming through transport, services and energy-linked channels. At the same time, the Monetary Authority of Singapore unexpectedly tightened policy by modestly increasing the rate of appreciation of the Singapore dollar nominal effective exchange rate policy band, even though core inflation had eased to 1.6 per cent.
MAS was not reacting only to current inflation. It was responding to the risk that underlying price pressures could intensify from July and remain elevated before easing around the middle of 2027, and it tightened into an economy that remains resilient, with second-quarter GDP growth of 5.7 per cent year on year. This is exactly the kind of policy decision an open economy makes when external friction begins to matter.
Singapore may be seeing softer housing momentum, but it is also exposed to freight costs, energy channels, imported inflation and global trade policy. When the cost of moving goods rises, and tariff uncertainty spreads through supply chains, a small and highly connected economy cannot treat those risks as distant. Singapore does not need to be the source of the friction to feel its effects.
AI Helps, but It Does Not Remove the Cost
There is still a powerful growth story running through parts of Asia.
Taiwan’s export orders jumped 59.4 per cent year on year in June to a record US$95.3 billion, driven by strong global demand for AI-related and technology products. Mega-cap technology earnings will also be closely watched this week, with companies such as Apple, Microsoft, Amazon, Meta and Samsung helping to shape expectations for the next phase of the AI investment cycle. AI demand continues to support equities, exports and manufacturing activity across parts of the region.
A strong technology cycle can lift orders for semiconductors, servers, electronics and advanced equipment. It can support markets and provide a growth engine at a time when other parts of the economy are slowing. Yet the goods still need to move. Components still cross borders. Energy still matters. Policy uncertainty still affects margins, investment plans and supply chain decisions.
AI may continue to provide a tailwind, but it is not a shield against higher freight costs, tariffs or geopolitical disruption. It can support growth while inflation risk remains uncomfortable, and it can help certain sectors outperform while broader market leadership narrows. AI keeps the cycle alive. Friction makes it more expensive.
The Cost of Doing Business Has Changed
The global economy is not simply slowing or accelerating. It is becoming harder to move through.
Goods cost more to ship when key maritime routes become riskier. Trade costs more to plan when tariffs return as a policy tool. Monetary policy costs more to loosen when labour markets remain tight, and inflation risks are still visible. Open economies such as Singapore have to manage all of this while staying connected to global demand and maintaining confidence in price stability.
This week’s developments are a reminder that inflation is not only a question of whether consumers are spending too much or whether wages are rising too quickly. It is also a question of how easily goods, energy, capital and policy can move through the system, and when that movement becomes more difficult, the cost shows up somewhere.
For investors, the important signal is not one tariff announcement, one shipping surcharge or one central bank decision taken in isolation. It is the way these developments are beginning to reinforce one another. Friction has moved from a background risk to a variable every part of the system now has to price in.
