Group 1: Report Industry Investment Rating - No information provided Group 2: Core View of the Report - Urea is experiencing a short - term high - level correction and will enter a mid - term oscillation pattern. In the short term, with a large amount of speculative funds leaving the market on Friday night, the commodity index has fallen from a high level, and urea futures are expected to follow suit. Also, with the strengthening of the basis, the liquidity of spot and futures sources in the spot market is expected to be released, bringing supply - side selling pressure to the spot market. In the medium term, urea is expected to oscillate mainly due to the ongoing anti - involution policy which supports the overall valuation of commodities, and the potential second - batch export of urea which may support the demand side. Overall, it is in a short - term correction with a unilateral weakening trend and is expected to oscillate in the medium term [3] Group 3: Summary by Relevant Catalogs 1. Fundamental Tracking - **Futures Market**: The closing price of the urea main contract was 1,803 yuan/ton (up from 1,785 yuan/ton), the settlement price was 1,798 yuan/ton (up from 1,782 yuan/ton), the trading volume was 236,179 lots, the open interest of the 09 contract was 171,609 lots (down 2,182 lots), the number of warehouse receipts was 2,523 tons (unchanged), and the trading volume was 849.507 million yuan (up 139.148 million yuan). The Shandong regional basis was - 13 (down from 25), the Fengxi - to - disk spread was - 113 (unchanged), the Dongguang - to - disk spread was - 23 (unchanged), and the UR09 - UR01 spread was - 4 (up from - 11) [1] - **Spot Market**: Among urea factory prices, Henan Xinlianxin was 1,850 yuan/ton (unchanged), Yankuang Xinjiang was 1,495 yuan/ton (up 35 yuan/ton), Shandong Ruixing was 1,810 yuan/ton (unchanged), Shanxi Fengxi was 1,690 yuan/ton (up 20 yuan/ton), Hebei Dongguang was 1,780 yuan/ton (unchanged), and Jiangsu Linggu was 1,880 yuan/ton (unchanged). Among trader prices, the Shandong region was 1,790 yuan/ton (down 20 yuan/ton), and the Shanxi region was 1,690 yuan/ton (up 20 yuan/ton). The supply - side indicators showed that the operating rate was 83.21% (up 1.04 percentage points) and the daily output was 192,650 tons (up 2,400 tons) [1] 2. Industry News - On July 23, 2025, the total inventory of Chinese urea enterprises was 858,800 tons, a decrease of 36,700 tons from the previous week, a month - on - month decrease of 4.10%. The inventory of domestic urea enterprises continued to decline this period, but the decline narrowed. With weak domestic demand, the overall order - taking and shipment of urea factories slowed down. However, due to some goods still being in the process of export collection and local downstream periodic bargain - hunting purchases, the overall urea factories showed a slight destocking. Some provinces saw an increase in enterprise inventory, while others saw a decrease. Overall, the urea trading has been weak for several consecutive days this week, and the second - batch export has not started yet. It is expected that the inventory of urea production enterprises will show a narrow - range oscillation pattern next week [1]
