The global economy continued its expansion in May 2026, driven in part by front-loaded orders as buyers sought to hedge against supply chain disruptions and price volatility. However, this growth remained subject to persistent headwinds, including elevated energy prices, sticky inflation, and heightened geopolitical risks. The U.S. economy avoided a recession, supported by a clear recovery in manufacturing, though easing labor market momentum and persistent inflationary pressures have kept the Federal Reserve cautious on the interest rate outlook. Meanwhile, Chinaโs economy expanded, but signs of a slowdown emerged due to softening manufacturing activity and subdued domestic demand.
The Thai economy grew at a sluggish and uneven pace in May 2026. While exports and selective investments provided key support, domestic consumption and private sector confidence remained weak. The Bank of Thailand projects 2026 GDP growth at a modest 1.5%, with headline and core inflation expected at 2.9% and 1.6%, respectivelyโhighlighting a stagflationary pattern characterized by low growth alongside rising cost pressures.
In summary, the global economy maintains a path of expansion, albeit one marked by fragility and elevated operational costs stemming from energy price pressures, Middle East tensions, elevated freight rates, and trade policy uncertainties. While global manufacturing was buoyed by precautionary inventory build-ups, the service sector and consumer demand showed signs of moderation across several major economies. Close monitoring remains necessary, particularly regarding policy rate trajectories ahead of the Monetary Policy Committee (MPC) meeting scheduled for Wednesday, June 24, 2026.
Weather
Thailand officially transitioned into the rainy season in May 2026, with the Thai Meteorological Department declaring its onset on May 15, 2026. The early part of the month was characterized by hot, humid conditions interspersed with summer storms, followed by an increase in rainfall intensity from mid- to late May. This shift was driven by the prevailing Southwest Monsoon over Thailand, accompanied by intermittent monsoon troughs passing through the upper regions of the country. Meanwhile, the southern region experienced intensified rainfall, particularly along the western coast.
Rubber Situation
In May 2026, the natural rubber market maintained a positive trajectory, with prices consolidating at elevated levels driven by robust global demand, particularly from China and the tire manufacturing industry. Meanwhile, supply avoided entering a surplus state as output from Thailand and key producing nations entered the market gradually, further constrained by seasonal leaf-flushing, adverse weather conditions, leaf-fall disease outbreaks, and agricultural acreage reallocation in select countries. These prevailing dynamics enable Thailand to preserve its export competitiveness while supporting revenue for rubber smallholders. Nevertheless, downstream industry operators are advised to rigorously manage raw material cost exposures and foreign exchange risks, particularly during this period of sustained high price levels.
In this regard, four critical factors remain essential to monitor: the Thai Baht exchange rate, crude oil prices, Chinese rubber inventory levels, and regional agri-climate risks alongside leaf fall disease outbreaks in Southeast Asia.
Additionally, crude oil prices exhibited heightened volatility stemming from Middle Eastern geopolitical tensions and elevated risks along major transport routes. Reuters reported on May 15, 2026, that Brent crude closed at USD 109.26 per barrel, while West Texas Intermediate (WTI) closed at USD 105.42 per barrel.
Regarding Thailand's natural rubber exports in April 2026, export volume reached 378,000 metric tons, valued at THB 23.5 billion. This underscores that Thai rubber exports remain at a substantial level, underpinned by resilient international market demand.
Crude Oil Prices: WTI & Brent
Crude oil prices sustained their volatile pattern following incremental progress in peace negotiations between the United States and Iran, despite ongoing discussions required to resolve remaining key issues. Meanwhile, global crude inventories continued to deplete at an accelerated pace, adding further momentum to market price fluctuations. The U.S. Energy Information Administration (EIA) reported that domestic crude oil inventories for the week ending May 22, 2026, contracted by 3.3 million barrels to settle at 441.7 million barrels.
