Energy Sets the Terms

A decision on diesel may tell us more about the global economy this week than the latest growth forecast. 

Ahead of the US midterm elections, President Trump agreed to import Russian diesel in an attempt to lower domestic fuel prices. It is an unusual move, and its significance goes beyond the fuel itself. US inflation accelerated to 3.7 per cent in September, with gasoline prices up 34.2 per cent from a year earlier and fuel oil up 74.2 per cent. More than half of the monthly increase in consumer prices came from gasoline alone. 

That makes energy more than another component of inflation. It has become a constraint on political choices, monetary policy and corporate planning at the same time. 

The global economy is still growing. The IMF has nudged its 2026 forecast higher, China’s exports are booming and Singapore has just recorded its strongest non-oil domestic export growth on record. Yet almost every encouraging number in this week’s data comes with the same qualification. If energy remains expensive, the cost of sustaining that growth rises with it. 

A Political Signal in the Fuel Market 

Energy prices become politically important long before they show up in an economist’s forecast. 

Petrol, diesel and electricity are unusually visible costs because households encounter them directly and frequently. Higher fuel prices also travel through transport, logistics, food and manufactured goods, which means their impact rarely stays confined to the energy component of an inflation basket. 

That is why the US decision to bring in Russian diesel is worth paying attention to. It suggests that domestic fuel costs have become pressing enough to influence policy decisions in the weeks before an election, at a time when inflation has moved in the wrong direction again. 

The Federal Reserve is watching the same problem from a different angle. Chair Kevin Warsh avoided signalling what the Fed will do at its October meeting, while reiterating that inflation remains uncomfortably high. The September rate increase took the policy range to 3.75 to 4.00 per cent, and most policymakers still expect another increase before year end. 

This leaves policymakers in an awkward position. The economy is not weak enough to demand urgent support, but energy-driven inflation makes it difficult to offer much relief. 

The Growth Forecast Comes With an Energy Clause 

The IMF’s latest outlook captures that tension neatly. 

Global growth for 2026 was revised slightly higher to 3.1 per cent, with the IMF expecting growth to strengthen to 3.4 per cent in 2027. Resilient advanced economies and investment in artificial intelligence helped support that upgrade. Yet the same forecast identifies high energy prices linked to the US-Iran conflict as a major risk, particularly for economies that depend heavily on imported energy. 

That qualification matters because energy shocks do not need to trigger a recession to cause damage. They can simply make an expansion more expensive. 

Higher fuel costs raise the price of moving goods and people. Businesses face higher operating costs. Households lose purchasing power. Central banks become more cautious, which keeps financing costs elevated for longer. Investment that looked attractive under cheaper energy and lower rates has to clear a higher hurdle. The cycle can therefore continue while becoming progressively harder to sustain. 

China illustrates the same tension. Its export engine remains exceptionally strong, with exports up 36.3 per cent year on year in September and its trade surplus reaching the second highest level on record. Yet producer prices rose 5.0 per cent, driven partly by higher fuel and raw material costs. Strong demand and strong exports do not cancel out the cost problem. They can coexist with it. 

Imported Inflation Becomes Singapore’s Test 

Singapore enters this environment from a strong position. 

The economy expanded 5.4 per cent year on year in the third quarter, ahead of expectations, while services remained firm and manufacturing continued to grow despite some moderation. September non-oil domestic exports then surged 68.4 per cent from a year earlier, the strongest increase on record, with electronics exports more than doubling. 

Those figures show how effectively Singapore is participating in the current global investment cycle. They also raise the stakes on the energy question, because an open economy that benefits quickly from global demand can import global cost pressure just as quickly. 

MAS kept monetary policy unchanged at its latest review after tightening earlier in the year. Its current inflation path assumes imported cost pressure will eventually fade, with core inflation expected to ease from mid-2027 and both core and headline inflation projected at 1.5 to 2.5 per cent in 2027. That assumption now has a very practical test. 

Singapore’s September consumer price data are due this Friday. If imported energy pressure is beginning to offset subdued domestic inflation, the room for policy patience becomes narrower. If those pressures remain contained, MAS has more flexibility to let the current growth cycle run without further tightening. The number will therefore matter for more than the inflation rate itself. It will show how quickly a global energy shock is reaching Singapore’s domestic economy. 

Energy Has a Different Kind of Risk 

There is a reason energy deserves more attention than many of the risks investors are already watching. 

A slowdown in AI spending, weaker corporate earnings or a cooling export cycle can often be anticipated through orders, guidance, capital expenditure plans and valuations. They may still surprise, but they usually leave evidence along the way. 

Energy moves differently because the catalyst is often geopolitical. Conflict in the Middle East and Ukraine continues to threaten global oil supply. A political announcement, a shipping disruption or a fresh escalation can alter the price of energy quickly, with the inflation effects following later through transport, production and household spending. 

That creates an asymmetry for policymakers and businesses. Growth plans, budgets and interest-rate expectations are made months in advance, while an energy shock can rewrite those assumptions in days. For Singapore, this matters because the current expansion remains heavily connected to global trade, manufacturing and technology demand. Higher energy and shipping costs can squeeze corporate margins even while export volumes stay strong, and households feel the same shock through transport and imported prices. 

The Variable That Sets the Terms 

Markets have spent much of this year debating whether growth can survive high rates, whether AI investment can continue and whether global trade can withstand geopolitical friction. 

Energy now sits across all three questions. It affects inflation, which influences interest rates. It affects transport and production costs, which influence corporate margins. It affects household purchasing power, which influences consumption. It affects government choices because fuel prices are among the most visible costs voters experience. 

That is why the diesel decision matters. One shipment of fuel does not change the global outlook on its own. What it reveals is how much weight energy prices now carry in the choices policymakers are prepared to make. 

The global economy remains resilient, and Singapore continues to benefit from strong trade and technology demand. The harder question is how long that strength can stay comfortable if energy keeps dictating the terms on which growth, inflation and policy have to operate. 

For now, the expansion is still intact. The price of keeping it that way is becoming more dependent on the price of energy.
