Core Viewpoint - The supply-demand dynamics indicate a continuation of a loose market environment, characterized by increased production and imports against weak demand and high inventory levels. Price expectations suggest that rubber prices may continue to fluctuate downwards, with a potential further contraction in the RU-NR price spread [1][25]. Supply Side - From January to April, China's natural rubber production increased by 26.15% year-on-year, currently in a seasonal growth phase. However, frequent rainfall in domestic production areas has delayed the concentration of raw material supply, leading to strong raw material prices as processing plants rush to collect materials. Improvement in weather conditions is anticipated to alleviate the tight supply situation [4]. - In early May, Thailand announced a one-month delay in tapping, but production has since resumed, with a year-on-year increase of 4.39% from January to April. Vietnam's production also saw a year-on-year increase of 2.10% during the same period. Although initial raw material output is slow due to weather disturbances, entering the peak production season may strengthen raw material supply expectations [4]. Demand Side - As of May 22, the operating rate for semi-steel tires was 73.74%, up 2.53% month-on-month but down 6.35% year-on-year. The operating rate for all-steel tires was 62.09%, up 2.21% month-on-month but down 4.11% year-on-year. The decline in rubber prices has led to increased caution among downstream producers, with only essential purchases being maintained. Despite a slight increase in production and sales of passenger vehicles, overall demand growth remains slow, and tire companies are facing high finished product inventories, which may lead to a downward adjustment in future operating rates [15][25]. - According to customs data, tire export figures for April showed a month-on-month decline, with all-steel tire exports down 5.43% and semi-steel tire exports down 10.39%. Although previous US-China negotiations had a positive impact on the market, strict tariff policies on Southeast Asian regions may continue to challenge tire export trade [23]. Market Outlook - The overall supply-demand situation remains loose, with expectations of increased natural rubber supply and high inventory levels in downstream tire companies, leading to a strong likelihood of downward adjustments in operating rates. The slow growth in terminal demand makes it difficult for upward price transmission, suggesting that rubber prices may continue to experience downward fluctuations, with the RU-NR price spread likely to contract [25].

Group 1 - The core viewpoint indicates that the Qingdao region's imported natural rubber market is experiencing a weak oscillation after a price increase, with STR20 spot prices reported at $1770-$1785 per ton, up 3.51% from late April, and Thai mixed prices around 14,400 RMB per ton, up 1.55% [1] - In early to mid-May, the market saw price fluctuations due to rising overseas raw material prices, strong futures, and a weaker USD against RMB, which boosted domestic prices [1] - Despite the positive macroeconomic developments from US-China trade negotiations, tire manufacturers maintained a cautious purchasing stance, leading to a lack of market confidence and a subsequent price correction towards the end of May [1] Group 2 - As of mid-May 2025, natural rubber inventory in Qingdao increased year-on-year by 16.78% in general trade warehouses and by 29.07% in bonded zones, influenced by lower purchasing activity from tire factories [2] - The market outlook for June suggests potential downward pressure on natural rubber prices due to increased upstream production and a seasonal decline in demand, with a focus on weather conditions affecting rubber tapping [2] - The market sentiment remains cautious due to weakening orders and uncertainties in the macro market, indicating that trading conditions may not improve significantly [5]

Report Industry Investment Rating - The investment rating for natural rubber (RU and NR) is neutral [3] - The investment rating for butadiene rubber (BR) is also neutral [3][4] Core Viewpoints - The price of natural rubber is expected to fluctuate within a range. The supply of domestic natural rubber is expected to increase, while the downstream demand is not expected to have significant highlights. However, the improvement in tire factory production profits and the easing of Sino - US tariffs have alleviated the previous pessimistic demand expectations, resulting in less prominent supply - demand contradictions [3] - The price of butadiene rubber may continue to be strong in the short term. The short - term supply of butadiene is tight, and the cost support for butadiene rubber has increased. Although the production profit of butadiene rubber has deteriorated, the downstream tire demand expectation has improved, and the upstream raw material price is firm [4][5] Market News and Data Futures and Spot Prices - RU主力合约 closed at 15,235 yuan/ton, up 240 yuan/ton from the previous day; NR主力合约 closed at 13,035 yuan/ton, up 180 yuan/ton.

Some enterprises' operations are not as good as before. Enterprises have introduced certain price - concession policies this month, but the sales rhythm is still slow, and overall sales have not increased significantly. Flexible production control may become the norm to relieve inventory growth [1] Upstream Device News - Dalian Hengli's 140,000 - ton/year butadiene plant stopped for maintenance on May 14, lasting about 30 days [1] Related Product Market Analysis Natural Rubber - **Spot and Spreads**: On May 14, 2025, RU basis was - 85 yuan/ton (+10), the spread between RU主力 and mixed rubber was 315 yuan/ton (+90), the import profit of smoked sheet rubber was - 6,222 yuan/ton (+225.71), NR basis was 61.00 yuan/ton (- 42.00); full - latex was 15,150 yuan/ton (+250), mixed rubber was 14,920 yuan/ton (+150), 3L spot was 16,200 yuan/ton (+150).
