China's big banks warn of more margin pressure in the second half

China's major state-owned banks are forecasting increased net interest margin (NIM) pressure for H2, following H1 results that saw sector-wide NIMs hit a record low of 1.42%. This ongoing compression, driven by central bank rate cuts, weak loan demand, and deflation, signals persistent profitability challenges for the sector, despite mixed first-half net profit outcomes. While overall non-performing loan values remained relatively flat, the ailing property sector continues to be a primary source of new NPLs, posing a significant risk to asset quality.

Analysis

China's major state-owned banks are signaling persistent profitability challenges for the second half of the year, driven by systemic net interest margin (NIM) compression. First-half results confirmed this pressure, with the sector's average NIM hitting a record low of 1.42%, significantly below the 1.8% threshold considered necessary for reasonable profitability. This erosion is a direct consequence of central bank rate cuts, deflationary pressures, and tepid credit demand, as evidenced by a record-low 6.9% year-over-year rise in outstanding yuan loans in July. While H1 net profit results were mixed—with Agricultural Bank of China and Bank of Communications posting modest gains of 2.7% and 1.61% respectively, while others like China Construction Bank saw unexpected declines—the universal drop in margins is the overriding theme. Asset quality remains a critical concern, with the ailing property market identified as the primary source of new non-performing loans. Despite relatively flat overall NPL values in the past six months, bank executives explicitly acknowledge the ongoing risk of an "unwinding of the real estate sector," which continues to cast a shadow over the industry's stability and future earnings potential.

Key Decisions for Investors

• Given the explicit guidance for continued net interest margin pressure and significant exposure to the struggling real estate sector, investors should maintain a cautious, and potentially underweight, position on the broader Chinese banking sector.
• Monitor key macroeconomic indicators closely, particularly monthly loan growth data and any further central bank interest rate adjustments, as these are the primary determinants of near-term profitability for these lenders.
• Note the performance divergence in H1 results; consider relative value strategies that favor banks demonstrating earnings resilience, like Agricultural Bank of China (601288.SS) and Bank of Communications (601328.SS), over peers that missed profit expectations, such as China Construction Bank (601939.SS).
