[SMM Analysis] Large-Sample Lithium Carbonate Inventory Officially Launched: How to Interpret the Data?

To more comprehensively and objectively reflect the overall industry inventory change trends, SMM has expanded the sample coverage for other segments in the weekly lithium carbonate inventory tracking.

This week, downstream weekly inventory stood at 42,729 mt, other segments weekly inventory (large sample) at 76,157 mt, smelter weekly inventory at 18,374 mt, and total weekly inventory (large sample) at 137,260 mt, down 0.8% WoW. 

As of this Thursday, the overall market inventory situation was as follows:

Upstream: Hedging registered warrants continued to increase

Upstream lithium chemical plants saw hedging registered warrant volumes continue to climb. The main reason was that futures prices remained at a relatively high level in the earlier period, traders' purchase pace slowed down, and lithium chemical plants' delivery willingness strengthened. As of now, total lithium carbonate warrants have exceeded 50,000 mt.

Downstream: Shift from wait-and-see to active restocking, with significant inventory buildup

Downstream material plants had low spot order purchase willingness during the earlier price highs, mainly relying on consuming prior inventory, early-month customer-supplied increments, and long-term contract orders to maintain production. As lithium carbonate prices gradually pulled back, material plants' procurement pace showed notable changes: during the early stage of the decline, restocking was primarily driven by rigid demand; as prices continued to fall, stockpiling willingness rose significantly, and buying sentiment turned positive. As a result, downstream material plants saw substantial inventory buildup this week.

Additionally, the replenishment from ex-China imports also deserved attention, as the volume of imported lithium chemicals converted into downstream inventory increased.

Other segments: Diverging inventory trends between battery cell manufacturers and traders

The "other" segment in this large sample mainly covered battery cell manufacturers and traders. Among them, battery cell manufacturers increased their lithium carbonate customer-supply volumes to material plants to control costs during the earlier price highs, resulting in some destocking of their own inventory; as prices continued to decline, battery cell manufacturers' long-term stockpiling willingness grew stronger.

Trader side, some enterprises, influenced by "invoicing economics," gradually slowed down their pace of taking spot orders from upstream lithium chemical plants. However, as prices pulled back and downstream buying sentiment turned positive, trader inventory saw significant destocking. Market Supplement: Gradual Conversion of Invisible Inventory to Visible Inventory

It is worth noting that as new goods in the market were largely absorbed by demand, some older goods gradually converted from invisible inventory to visible inventory, circulating and being traded in the market. This was also one of the important reasons driving the current increase in warrant volume.
