Why did ASEAN manufacturing strengthen again in May: regional resilience and structural pressure behind the rebound in orders

Why ASEAN Manufacturing Strengthened Again in May: Regional Resilience and Structural Pressures Behind the Order Rebound

ASEAN manufacturing showed a notable signal in May: business conditions accelerated again, but the recovery was uneven.

According to S&P Global data, ASEAN’s manufacturing Purchasing Managers’ Index (PMI) rose from 50.7 in April to 51.5 in May, staying above the boom-bust line for the 11th consecutive month and rebounding for the first time after three straight months of slowdown. On the surface, this means regional manufacturing activity regained support in the middle of the second quarter; but a closer look at the data shows that the improvement mainly came from new orders and output, while external demand, logistics, and costs still posed clear constraints.

The rebound in orders shows that the regional manufacturing chain still has endogenous resilience

The most important change in May was new orders. S&P Global noted that growth in new orders hit a three-month high, and output also recovered into stronger, though still modest, growth after nearly stalling in April.

Such changes usually imply two things. First, regional manufacturers have not entered a broad contraction cycle, and end-demand is still supporting production momentum. Second, the mutual pull between ASEAN’s internal market and regional supply chains is becoming a more stable source of support than a single external demand source.

This is important for ASEAN. For many years, regional manufacturing has been seen mainly as a recipient of global orders, especially dependent on external demand from the U.S., Europe, and China. But amid greater global demand volatility and rising uncertainty in trade policy, ASEAN manufacturing resilience is increasingly determined by two capabilities: production coordination within the region, and the ability of local and neighboring markets to absorb consumption.

In other words, the May PMI rebound is not just a short-term sentiment indicator; it also seems to be reminding the market that ASEAN’s manufacturing chain is transitioning from an “export-demand-driven” model toward a regional manufacturing system with both internal and external circulation.

But declining exports show that the recovery is still constrained by global trade disruptions

In sharp contrast to the improvement in new orders and output, export sales fell for a third consecutive month, and at the fastest pace since September 2024.

This suggests that ASEAN manufacturing’s external environment remains unstable. Even if demand within the region has improved, weak export orders will still weigh on further manufacturing expansion. For ASEAN countries with strengths in electronics, electrical equipment, components, machinery, and intermediate goods, export declines typically affect not only finished-goods shipments, but also parts procurement, inventory management, freight arrangements, and factory utilization rates.

From a regional development perspective, this divergence says a lot about the current stage of ASEAN manufacturing: supply-chain restructuring has not eliminated global trade fragility; instead, it has left firms facing both “new opportunities” and “new volatility.” As some production capacity continues to shift to ASEAN, regional countries gain more opportunities to attract manufacturing investment and take on orders; at the same time, ASEAN is also becoming more deeply embedded in the global trade cycle, and its sensitivity to external market changes has not diminished.

Delivery delays ease, but supply-chain efficiency remains key to ASEAN competitivenessAnother notable detail in May is that supplier delivery times continued to lengthen, but the extent of the delay was the mildest in nine months.

This suggests that supply chain conditions in ASEAN manufacturing are not deteriorating; rather, they are still experiencing frictions during the improvement process. For manufacturers, delivery cycles affect not only inventory and cash flow, but also directly determine whether firms can fulfill orders steadily, reduce costs, and strengthen customer stickiness. For ASEAN’s regional production network, which depends on the cross-border flow of components and raw materials, logistics efficiency itself is part of competitiveness.

This is why intra-ASEAN connectivity, port and shipping networks, regional logistics systems, and the supporting capacity of industrial parks continue to be underlying variables in manufacturing competition. While changes in delivery times in the PMI are only a technical indicator, what they actually reflect is the smoothness of the entire regional industrial chain.

If ASEAN hopes to continue attracting manufacturing relocation, low-cost labor alone is no longer enough. Whether it can form more efficient cross-border supply chain coordination is gradually becoming a more important dividing line.

Inventory declines, showing firms are still cautiously managing capacity

The data show that ASEAN manufacturers used inventory to meet production needs in May, so both input inventories and finished goods inventories declined slightly.

This indicates that firms remain cautiously optimistic about a recovery in future demand, but have not yet fully entered a restocking cycle. In other words, the current improvement in output is more like a response to existing orders than a forecast of strong long-term demand.

This kind of inventory behavior is common in the early stages of a regional recovery: firms first use existing stocks to complete deliveries, reducing capital tied up and avoiding overexpansion of purchases when external demand remains unstable. For manufacturers with tight cash flow and a high dependence on imported raw materials, this is a relatively rational defensive move.

But at the macro level, continued inventory decline also means that if orders do not expand further later on, manufacturing growth may still be constrained by passive replenishment rather than proactive expansion.

Cost pressures remain, but room for price transmission is limited

The May survey showed that price pressures remained “quite substantial,” though the pace of increases in input costs and output charges both slowed from April.

This reflects the ASEAN manufacturing sector being in a delicate phase of cost balance. On the one hand, costs related to raw materials, energy, transport, and labor may still be hit by external shocks; on the other hand, firms may not have sufficient pricing power to fully pass on costs to downstream customers.

For ASEAN’s industrial system, which is oriented toward exports and intermediate goods manufacturing, this situation is especially worth watching. If input costs rise while export sales remain under pressure, firms’ profit margins will be squeezed from both sides. This will affect not only short-term profitability, but also the pace of capital expenditure, automation investment, and capacity upgrading in the next stage.

Therefore, the competitive focus of ASEAN manufacturing is shifting from simply “whether orders can be secured” to “whether a more stable structural advantage can be built across cost, efficiency, and delivery.”

Business confidence rebounds, suggesting firms are still betting on the latter part of the second quarterDespite external challenges still lingering, business confidence rose to a four-month high in May, indicating that manufacturers broadly expect output to keep growing over the next 12 months.

This rebound in confidence matters because it shows companies have not abandoned expansion plans because of short-term volatility. For ASEAN, manufacturing confidence is often closely tied to decisions on capital expenditure, factory expansion, equipment upgrades, and supply-chain localization. If the improvement in confidence can be sustained, it usually translates into more concrete investment and hiring behavior in the months that follow.

However, S&P Global economist Maryam Baluch also noted that trade disruptions and war-related inflationary pressures will continue to weigh on growth. In other words, improving confidence does not mean risks have disappeared. The recovery in ASEAN manufacturing still depends on whether the global trade environment improves and whether companies in the region can more effectively hedge against external shocks.

Greater significance for ASEAN regional development: manufacturing recovery is becoming “more regionalized”

From an ASEAN perspective, the significance of the May PMI rebound does not lie in the monthly data itself, but in the fact that it once again proves that ASEAN manufacturing is becoming a production network with stronger intra-regional circulation characteristics.

Over the next few years, what determines ASEAN manufacturing’s position may not simply be whether one country secures more orders, but whether the region can form a more complete division-of-labor system:

• whether upstream raw materials and components can flow more efficiently within the region;
• whether midstream manufacturing bases can complement one another across Vietnam, Thailand, Malaysia, Indonesia, the Philippines, and Singapore;
• whether downstream markets can absorb more capacity through regional consumption upgrading;
• whether logistics, ports, shipping, and digital supply chains are sufficient to support cross-border coordination.

Against this backdrop, the rebound in ASEAN manufacturing conditions is not a uniform “broad-based recovery,” but rather a structural process: external orders still matter, but regional coordination, supply-chain efficiency, and the expansion of local markets are becoming new growth anchors.

If ASEAN manufacturing’s appeal in the past mainly came from cost advantages, then in the next stage its appeal may come more from “regional connectivity” and “supply-chain reliability.” This is also the ASEAN Economic Community’s (AEC) real long-term challenge.

Conclusion: there is a recovery, but ASEAN manufacturing is still navigating multiple constraints

The May PMI data show that ASEAN manufacturing has not lost its growth momentum. The rebound in new orders and output provided a more positive starting point for the second quarter; but declines in exports, delivery delays, inventory contraction, and cost pressures also remind the market that this recovery is far from easy.

For ASEAN, what really matters is not whether a single month returns to expansion territory, but whether the regional manufacturing system can build stronger internal resilience amid global uncertainty. Going forward, those who do better in supply-chain coordination, logistics efficiency, industrial division of labor, and market connectivity will be more likely to take the lead in the new competitive landscape of ASEAN’s manufacturing hub.
