Bosera Market Commentary March 17: The three major indices fluctuate, ChiNext drops over 2%

🌟【Bosera Market Review March 17】Three Major Indices Adjust, ChiNext Falls Over 2%

📝Daily Viewpoint

🎈Today, the Shanghai and Shenzhen three major indices adjusted, with the ChiNext Index falling over 2%. Market turnover continued to shrink compared to yesterday, totaling 2.22 trillion yuan. From March 15 to 16, local time, Chinese and U.S. trade representatives, including Vice Premier He Lifeng and U.S. Treasury Secretary Janet Yellen, held economic and trade consultations in Paris, France. Main topics included tariff arrangements, promoting bilateral trade and investment, and maintaining existing consensus. Both sides agreed to explore establishing a cooperation mechanism to facilitate bilateral trade and investment and to continue negotiations. Currently, the market is gradually pricing in an extended duration of the US-Iran conflict, with crude oil prices likely remaining high, triggering a macro re-pricing chain of “supply-side shocks—rising inflation—passive tightening of financial conditions,” which impacts corporate profits, liquidity, and risk appetite in the equity market. In the short term, caution is advised regarding market volatility, with balanced allocations and a focus on defensive assets such as dividends.

🔥News Highlights

🎈From March 15 to 16, China and the U.S. held trade negotiations in Paris. Li Chenggang, China’s International Trade Negotiator and Vice Minister of Commerce, stated that over the past day and a half, both teams engaged in honest, in-depth, and constructive discussions, reaching preliminary consensus on some issues. Both sides will continue to maintain the negotiation process.

Brief Comment: This is the first face-to-face contact between China and the U.S. amid escalating friction, and achieving preliminary consensus is a positive signal. Discussions on adjusting tariff levels and delaying non-tariff measures indicate both sides’ willingness to manage differences and prevent further deterioration of economic and trade relations. The idea of establishing a cooperation mechanism to promote bilateral trade and investment provides a institutional framework for future dialogue. The results of the negotiations help stabilize market expectations for China-U.S. relations, but attention should be paid to the follow-up of the U.S. Section 301 investigation and possible countermeasures by China, as the long-term nature of trade frictions may remain unchanged.

🎈On March 16, the Ministry of Industry and Information Technology, Ministry of Finance, and National Development and Reform Commission officially issued the “Notice on Conducting Hydrogen Energy Comprehensive Application Pilot Projects.” The notice clarifies that by 2030, hydrogen energy in urban clusters will achieve large-scale application across multiple fields, with the average terminal hydrogen price reduced to below 25 yuan per kilogram, aiming for around 15 yuan per kilogram in some advantageous regions. The nationwide fuel cell vehicle fleet is expected to double compared to 2025, reaching 100,000 vehicles.

Brief Comment: This “Notice” marks a critical policy turning point from industry “0 to 1” towards “1 to N.” Its core change involves shifting subsidies from solely fuel cell vehicles to diversified industrial scenarios such as green ammonia and hydrogen metallurgy. This strategic adjustment clarifies the path of commercializing large-scale industrial applications to reduce overall industry chain costs and drive down terminal hydrogen prices. Investment logic is shifting from simple vehicle promotion to broader industrial green hydrogen applications, with related technological upgrades expected to be released.

🎈On March 16, the Shanghai Branch of the People’s Bank of China, together with the Shanghai Regulatory Bureau of the China Financial Supervision and Administration, issued the “Notice on Adjusting the Minimum Down Payment Ratio for Commercial Property Loans in Shanghai.” The notice states that from March 16, 2026, onward, the minimum down payment ratio for commercial property (including “commercial-residential mixed-use” properties) in Shanghai will be adjusted to no less than 30%. This is the first adjustment to Shanghai’s commercial and office property loan policies in over ten years.

Brief Comment: The central bank and the China Financial Supervision and Administration issued a document in January this year to unify the minimum down payment ratio for commercial property loans nationwide at no less than 30%, requiring local branches to implement city-specific policies. Shanghai’s adjustment is a concrete implementation of the national policy and marks a substantial step in activating existing assets in first-tier cities. Lowering the down payment from the usual 50% to 30% directly reduces entry barriers for investors and institutions, helping to stimulate potential demand previously limited by capital thresholds.
