Core Insights - The July PPI improved on a month-on-month basis but remained unchanged year-on-year at -3.6%, slightly below market expectations, indicating a disconnect in price transmission from upstream raw materials to downstream industries [1][2] - The "anti-involution" policy has led to significant price increases in key commodities such as coal, steel, and lithium, but these increases have not effectively translated into higher industrial product prices [2][3] - The ongoing "pig cycle misalignment" has resulted in CPI slightly exceeding market expectations, driven by unexpected price increases in core goods, energy, and other services [5][6] PPI Analysis - The month-on-month PPI improved due to rising commodity prices, but the year-on-year figure did not show improvement, highlighting weak downstream demand and limited pricing power for enterprises [1][3] - The analysis framework indicates that while upstream raw material prices have improved, the PPI for downstream industries has continued to decline, particularly in the export chain [4] - The dual impact of supply-side policies and demand-side pressures is evident, with the export chain facing significant downward pressure [4] CPI Insights - The CPI for July was reported at 0.0% year-on-year, slightly above the expected -0.1%, driven by durable goods benefiting from trade-in subsidies and rising energy prices [5][6] - The increase in CPI was significantly influenced by the price hikes in gold and platinum jewelry, contributing approximately 0.22 percentage points to the overall CPI [5] - Expectations for CPI improvement are projected for September, considering the ongoing misalignment in the pig cycle and slow recovery in consumer spending [6] Market Implications - The bond market may experience low volatility as CPI and PPI figures align closely with market expectations, with a focus on inflation recovery and potential demand-side policies [7] - The overall economic environment remains sensitive to both domestic policy effectiveness and international trade dynamics, which could influence future market performance [7]

Price Index Insights - In July, the main raw material purchase price index and the factory price index were 51.5% and 48.3%, respectively, increasing by 3.1 and 2.1 percentage points from the previous month[8] - The main raw material purchase price index returned above the threshold for the first time in five months, indicating a strong response from enterprises to price expectations under the "anti-involution" policy[8] - The black metal smelting and rolling industry had the highest factory price index at 88.9%, with a month-on-month increase of 80.1 percentage points and a year-on-year increase of 74.5 percentage points[14] PMI Performance by Sector - The comprehensive PMI for "anti-involution" industries recorded 48% in July, up from 47.8% in the previous month, but still below the critical point[21] - Non-"anti-involution" industries maintained a PMI of 50.1%, down from 50.9%, indicating continued expansion[21] - Different enterprise sizes showed varied performance, with large, medium, and small enterprises' PMI at 50.3%, 49.5%, and 46.4%, respectively, reflecting a decline for large and small enterprises while medium enterprises improved[25] Policy and Seasonal Effects - The July Politburo meeting calibrated market expectations for the "anti-involution" policy, suggesting that the manufacturing PMI may remain below the threshold in August[26] - Extreme weather conditions, including record rainfall in Hebei and Inner Mongolia, are expected to further impact production in July and August, leading to a weaker PMI outlook[39] - The "anti-involution" policy's first month showed a divergence in PMI across sectors and enterprise types, influenced by both policy and seasonal effects[25] Risk Factors - Potential risks include domestic policy effectiveness falling short of expectations and unexpected changes in international geopolitical situations[45] - Measurement errors in PMI indicators related to "anti-involution" industries may arise due to incomplete industry self-regulation[45]

Group 1: Report Industry Investment Rating - Not provided Group 2: Core Viewpoints of the Report - The futures prices of coking coal and coke declined due to market sentiment fluctuations, but the spot market maintained low inventories and strong rigid demand, with price support still in place. The supply - demand of coking coal and coke remained slightly tight, and the fifth round of price increase for coke started. There was a policy bottom, and buying opportunities after price corrections could be considered [1] Group 3: Summary by Related Catalogs Market Overview - On July 31, all black - series commodity futures turned down. The closing price of rebar was 3205 yuan/ton, down 4.19%; the hot - rolled coil futures closed at 3390 yuan/ton, down 3.56%; the iron ore futures closed at 779 yuan/ton; coking coal and coke declined, with coking coal hitting the daily limit down [1] Market Analysis - The decline in the futures market cooled the previous positive sentiment. Some traders sold to realize profits, and the increase in auctions narrowed. Extreme rain in coal - producing areas led to a temporary reduction in coal supply. Coking coal demand remained strong due to high downstream coke - enterprise operating rates and high pig - iron production. Coal mine pre - sales would last until mid - August. The inventory of washed coal plants and coking coal mines reached low levels. After the fourth round of price increases for coke, the profits of coke enterprises continued to shrink, some reduced production, and supply tightened. Steel mills and traders had good procurement enthusiasm, and coke inventories at coking plants were low. The coking industry decided to raise coke prices starting from July 31 [1] Investment Suggestions - For iron ore, pay attention to supply - demand changes and inventory levels and avoid chasing high prices. For rebar, take a short - term oscillatory approach and focus on the spread between hot - rolled coil and rebar. For hot - rolled coil, take a short - term high - level consolidation approach and focus on supply - demand changes. For coking coal and coke, pay attention to the oscillatory market after the decline stabilizes or the strength - weakness relationship between the two [1]

Core Points - The manufacturing PMI for July is reported at 49.3%, a decrease of 0.4 percentage points from the previous month, primarily influenced by seasonal production slowdowns and adverse weather conditions [1][3] - The non-manufacturing business activity index and the composite PMI output index are at 50.1% and 50.2%, respectively, both showing a decline but remaining above the critical point [1][3] - Economic recovery fundamentals remain solid, with the equipment manufacturing and high-tech manufacturing PMIs continuing to expand, indicating ongoing structural optimization [1][3] Manufacturing Sector - The manufacturing PMI's decline is attributed to traditional production off-seasons and extreme weather events, leading to a weaker demand side [2][3] - Despite the overall PMI decline, production activities in manufacturing are still expanding, particularly in the equipment and high-tech sectors, which are crucial for economic growth [3][5] Price Indices - Among the 13 sub-indices of the manufacturing PMI, the purchasing price index and the ex-factory price index have risen, indicating improved market conditions in certain sectors [5] - The main raw material purchasing price index has risen to 51.5%, marking the first increase above the critical point since March, suggesting a potential recovery in material costs [5] Non-Manufacturing Sector - The non-manufacturing business activity index is at 50.1%, reflecting a slight decline, but summer consumption is beginning to show positive effects in retail, travel, and entertainment sectors [7][9] - Retail activity is increasing, with the retail business activity index rising above the critical point, indicating strong consumer purchasing intentions [8] Future Outlook - The implementation of policies aimed at expanding domestic demand, such as "two new" and "two heavy" initiatives, is expected to support stable economic expansion and quality improvement in the second half of the year [1][9] - The positive impact of summer consumption is anticipated to continue into August, contributing to economic recovery [9]

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - The market is somewhat cautious, and the black - related products are oscillating weakly. Steel prices are affected by factors such as the off - season consumption, production changes, and market sentiment. Iron ore prices are influenced by global shipments and iron - water production. Double - coking products are in a state of multi - empty game, and power coal prices are affected by supply, demand, and market sentiment [1][3][6][8] 3. Summary by Related Categories Steel - **Market Analysis**: Yesterday, the futures prices of rebar and hot - rolled coils were 3061 yuan/ton and 3191 yuan/ton respectively. The national urban inventory of building materials was 375.07 million tons, a 1.29% month - on - month increase, and the hot - rolled coil inventory was 174.22 million tons, a 1.87% month - on - month increase. The national building materials transaction volume was 96,000 tons. Building materials are in the off - season, with a slight increase in production and low inventory. Plate production has a slight month - on - month increase, and the current export remains high. The market lacks speculative demand, and the weak off - season demand will suppress steel prices [1] - **Strategy**: Unilateral trading is expected to be oscillating, while there are no strategies for inter - period, inter - variety, spot - futures, and options trading [2] Iron Ore - **Market Analysis**: Yesterday, the futures price of iron ore weakened slightly, with the main 2509 contract closing at 731 yuan/ton, a 0.68% decline. The prices of mainstream imported iron ore varieties at Tangshan Port remained stable. The global iron ore shipments decreased significantly this period, with a total of 29.95 million tons. The daily transaction volume of national main ports decreased by 8.14% month - on - month, and the forward spot transaction volume decreased by 13.13% month - on - month. In the short term, the iron ore price has rebounded, and the basis discount has been significantly repaired. In the long term, the supply - demand pattern is relatively loose [3] - **Strategy**: Unilateral trading is expected to be oscillating, while there are no strategies for inter - period, inter - variety, spot - futures, and options trading [4] Double - Coking Products - **Market Analysis**: Yesterday, the futures of double - coking products oscillated. The spot market of port coke was stable, and the domestic market sentiment improved. The inventory of the two ports increased slightly. The price of coking coal in the main production areas oscillated weakly. The expectation of domestic coal mine resumption is increasing, and the supply is expected to increase. The iron - water production of steel mills is at a high level but shows a downward trend. The supply - demand of coking coal has improved slightly. The profit of coke enterprises is not good, but the downstream steel demand has improved. In the short term, the supply - demand of coke has improved slightly, and in the long term, it is still in a relatively loose pattern [6] - **Strategy**: Both coking coal and coke are expected to oscillate in unilateral trading, while there are no strategies for inter - period, inter - variety, spot - futures, and options trading [7] Steam Coal - **Market Analysis**: The price of steam coal in the main production areas oscillated weakly.

The high - calorie Australian coal has a price inversion with the domestic winning bid price, and the low - calorie Indonesian coal has obvious cost - performance advantages [8] - **Strategy**: No strategy is provided [8]

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - The market misinterprets the Central Financial and Economic Commission meeting as a new round of supply - side reform in the upstream of the industrial chain, but the actual target is anti - involution in the downstream manufacturing sector, so the price increase may not be sustainable [2]. - The real estate market is still in the process of bottom - building, and the economic data in May was slightly below expectations while the PMI data in June improved month - on - month. The current state of the steel market is weak supply and demand, and with the arrival of high - temperature weather, demand will further weaken and inventory is expected to rise slightly [2]. - Currently, the iron ore market is affected by factors such as the decline in steel mill iron - water production, high global shipments, and high proportion of trade ore inventory, but in the short term, it may maintain a slightly stronger oscillatory trend driven by the price increase of products like rebar and glass [5]. Summary by Relevant Catalogs I. Rebar and Hot - Rolled Coil - **Market Situation**: The market misinterprets the Central Financial and Economic Commission meeting. The real estate market is bottom - building, economic data in May was slightly below expectations, and PMI in June improved. The steel market is in a state of weak supply and demand, and demand will weaken with high - temperature weather [2]. - **Supply and Demand Data**: This week, rebar production increased, factory inventory decreased, social inventory increased, and total inventory decreased slightly. Apparent demand rebounded slightly month - on - month. The 247 - steel - mill average daily iron - water volume decreased by 1.44 million tons (- 0.59%) compared to last week, and the national building materials steel mill rebar production increased by 3.24 million tons (1.49%) [2][3]. - **Price Data**: The rebar steel main contract closing price was 3072 yuan/ton, up 2.57% from last week; the hot - rolled coil main contract closing price was 3201 yuan/ton, up 2.56% from last week.
