Total rebar inventory stood at 8.2948 million mt this week, up 277,000 mt WoW, or 3.46% (previous: +11.33%), and up 363,200 mt from the same period of the previous lunar year, or 4.58% (previous: +4.6%).

Construction steel inventory continued to build up this week. Supply side, maintenance at blast furnace steel mills eased marginally this week, with hot metal flowing back to construction steel products; EAF steel mills resumed production successively, and the capacity utilization rate improved WoW, lifting the overall supply level of construction steel. Demand side, market demand gradually started to recover, the pace of downstream construction site resumptions accelerated, and rigid-demand purchases improved WoW, driving an overall rebound in apparent consumption. Overall, both supply and demand increased this week. Although total construction steel inventory continued to build up, the pace of increase slowed significantly.

In-factory rebar inventory stood at 2.4975 million mt this week, up 24,700 mt WoW, or 1% (previous: +8.4%), and up 83,200 mt YoY, or 3.45% (previous: +3.57%). As the advantage of flat steel products was weaker than in the previous period, some hot metal flowed back to construction steel. Meanwhile, EAF steel mills resumed production as expected, increasing the overall supply of construction steel. At the same time, downstream construction sites resumed work successively, and some direct-supply demand recovered. Therefore, although in-factory construction steel inventory increased this week, the pace of increase slowed significantly.

Rebar social inventory stood at 5.7973 million mt this week, up 252,300 mt WoW, or 4.55% (previous: +12.69%), and up 280,000 mt YoY, or 5.08% YoY (previous: 5.07%). Futures fluctuated at current levels, and market participants remained cautious about the outlook. Trading sentiment was moderate, with transactions still mainly driven by rigid-demand purchases, and social inventory continued to build up.

Affected by the gradual resumption of supply and the lagged recovery in demand, construction steel inventory is expected to continue to increase slightly next week. However, given that the concentrated production resumptions at electric furnace mills have largely come to an end, and there is a lack of large-scale new production release going forward, supply-side growth will likely flatten out. Coupled with the full resumption of downstream construction sites and the continued release of end-user procurement demand, the market supply-demand pattern will gradually improve.

Shennan Circuits Reports Strong PCB, Packaging Substrate Business Growth & Project Progress

Shennan Circuits disclosed its investor relations activity record. The PCB business benefited from growing demand for AI computing infrastructure hardware-related products, with factory capacity utilization rates staying high. The packaging substrate business, driven by demand boosts from storage and processor chip substrates, maintained the elevated capacity utilization rate levels seen since Q4 2025. For the Guangzhou packaging substrate project, the capacity ramp-up of BT-type packaging substrates progressed steadily. FC-BGA packaging substrates achieved mass production of products with 22 layers and below, while R&D and sampling of products with 24 layers and above advanced on schedule. The Nantong Phase IV and Thailand factory projects were successfully connected and put into production in H2 2025, with capacity currently ramping up steadily. Capital expenditure in 2026 will primarily focus on PCB and packaging substrate businesses, with key investments directed toward the Wuxi high-speed, high-density, and high-multilayer electronic circuit product project, the Guangzhou packaging substrate factory construction, as well as subsequent payments for the Nantong Phase IV and Thailand factory projects.

Ferrous Metals Maintain Fluctuating Trend in the Short Term [SMM Steel Industry Chain Weekly Report]

This week, ferrous metals rose and then pulled back, moving sideways overall, with coking coal and coke experiencing a more notable pullback. In the first half of the week, market rumors suggested that a thermal coal supply assurance meeting would be held on Friday, which, combined with the sharp pullback on the raw material side driven by industrial capital fleeing, led to an overall pullback in ferrous metals. In the second half of the week, Trump's visit to China and trade negotiations proceeded simultaneously, but futures had already priced this in earlier, with no significant fluctuations. When the five major steel product data were released, supply showed some divergence, demand generally increased, and inventory destocking was strong. Spot market side, spot prices were held relatively firm, market transactions were mostly at low prices, and when the spot-futures price spread widened, basis traders were seen making shipments...
