China's banking sector has flipped from net lender to net borrower in short-term funding markets for the first time in seven months. The shift was driven by a surge in negotiable certificate of deposit (NCD) issuance, as banks sought wholesale funding to cover liquidity gaps.

NCDs are short-term debt instruments banks use to raise cash from other financial institutions. Historically, state-owned giants like ICBC and Bank of China acted as net suppliers, lending to smaller and mid-tier banks. But that dynamic has reversed.

The People's Bank of China (PBOC) compounded the pressure by executing a net withdrawal of 200 billion yuan-roughly $27.5 billion-through its one-year medium-term lending facility (MLF) in April. The central bank is actively pulling liquidity, while banks feel the pinch enough to borrow.

As of July 2024, Chinese banks' liabilities to non-bank financial institutions stood at 7.7% of total liabilities, while claims on those same institutions were only 6.6%. That gap highlights the banking system's reliance on non-bank funding channels-a trend the PBOC aims to normalize.

The dual signal of liquidity tightening and rising NCD issuance is likely to increase pressure on smaller banks already under regulatory scrutiny for balance sheet quality and exposure to local government debt. If wholesale funding costs rise significantly, some of these institutions could face margin strain.
