Geopolitical Risk Brief: October 2026

September’s growth and trade indicators point to economic resilience, but broadening commodity-price pressures and tighter financial conditions complicate the outlook for demand and margins. 

This month, we explore developments in the Russia-Ukraine conflict and in Brazil's presidential election and what they could mean for energy-infrastructure risk and market access. 

Can stronger demand withstand rising costs and tighter financial conditions?

S&P Global’s Purchasing Managers’ Index™ (PMI®) data provide evidence of stronger activity. The global composite output index improved for a sixth consecutive month in September, matching its highest level since 2021. Stronger new export orders also align with trade flows: year-over-year growth in world trade volumes exceeded 7% during the third quarter to date, matching the strongest rate since 2021.

The national picture is less uniform. Exceptional strength in the US composite output index contrasts with mixed readings across other major economies. The October flash PMI releases, scheduled for Oct. 23, will help test whether the US surge persists and whether growth strengthens elsewhere. That distinction matters for companies evaluating demand across multiple markets.

Energy and food-price pressures, fueled by conflict- and weather-related disruptions, threaten to complicate the outlook. Limited additional monetary tightening remains the base case, partly because energy-price pass-through to core inflation has been modest so far. That assessment becomes harder to sustain if commodity pressures broaden, with delayed pass-through adding uncertainty.

Higher real yields and widening sovereign spreads are also tightening financial conditions beyond central-bank policy rates. 

Does the Russia-Ukraine energy outlook justify changing disruption assumptions?

A change in permitted energy supply is not the same as a reduction in the risk of infrastructure disruption. The US government on Oct. 9 issued a general license permitting transactions related to Russian-origin diesel through April 7, 2027, alongside planned deliveries and an easing of Russian diesel-export restrictions. These developments concern supply arrangements; they do not establish that the underlying conflict risk has diminished.

A US announcement of an energy ceasefire has not been confirmed by Russia or Ukraine. Reported limits on its scope are important: An agreement covering oil refineries alone would leave other energy infrastructure outside its protection.

S&P Global Market Intelligence’s assessment is that Ukraine would be very unlikely to accept such an arrangement unless Russia also halted strikes on electricity and gas infrastructure—a concession assessed as highly improbable. 

How could Brazil's election change access to the US market?

Brazil’s presidential runoff presents a conditional market-access opportunity rather than an implemented trade-policy change. A Flávio Bolsonaro victory would probably bring closer alignment with the US and improve bilateral economic relations. Strong results for aligned candidates in Congress and local government would also support the passage of preferred policies.

The potential commercial effects include lower or removed US tariffs on Brazilian exports, expanded tariff-rate quotas and other preferential arrangements. Those outcomes remain contingent: An election result would first need to translate into policy direction, negotiations and implemented measures. Political alignment alone would not establish new terms of access.

Nor would closer US relations necessarily mean severing trade ties with mainland China, with likely opposition from Brazil’s influential agribusiness sector as a constraint. 

How do these developments connect?

These developments test different parts of a corporate plan. The PMI and trade data inform demand expectations; energy-security developments affect uncertainty around availability and costs; and political change can create conditional routes to improved market access. They do not share a single timetable or provide interchangeable evidence of improvement.

The common planning challenge is to distinguish a positive signal from a durable change. Stronger activity can coexist with higher operating costs, additional energy supply with continuing infrastructure risk, and closer political alignment with unchanged trade measures. 

Which signals could change the assessment?

• October PMI releases: Does September's strength persist and extend beyond the US? 
• Commodity prices and inflation pass-through: Are cost pressures becoming more persistent, potentially impacting input costs and margins?
• Policy rates, real yields and spreads: If financial conditions tighten further, 
• Confirmed energy-supply and infrastructure developments: Has disruption risk materially changed, or only supply arrangements?
• Brazil's election outcome: Does political change translate into implemented market-access changes?

October’s key test is whether stronger activity can persist amid energy and financial pressures. The next PMI readings will help assess demand durability, while confirmed energy developments and implemented trade measures will determine whether country-specific assumptions also need to change. Until then, positive signals and a changed operating baseline remain different propositions.
