China’s banking sector just flipped from net lender to net borrower in short-term funding markets, a reversal that hasn’t happened in seven months. The mechanism: a significant ramp-up in negotiable certificates of deposit issuance, the financial plumbing through which Chinese banks tap wholesale funding.

What actually happened

Negotiable certificates of deposit, or NCDs, are short-term debt instruments that banks issue to raise cash from other financial institutions. When banks issue more NCDs than they buy from peers, they become net borrowers. That’s exactly what just happened across China’s banking system for the first time since late 2025.

NCDs have been a critical funding tool since China introduced them in 2015. They’re used primarily by smaller and mid-tier banks that lack the vast deposit bases of state-owned giants like ICBC or Bank of China. Historically, those state-owned behemoths have acted as net suppliers in the NCD market, essentially lending surplus liquidity to their smaller counterparts during periods of stress.

The PBOC’s balancing act

In April, the PBOC executed a net withdrawal of 200 billion yuan through the one-year medium-term lending facility, or MLF. That’s roughly $27.5B at current exchange rates, pulled out of the banking system in a single operation designed to tighten conditions.

As of end-July 2024, Chinese banks’ liabilities to the non-bank financial institution sector stood at 7.7% of total liabilities, while their claims on those same institutions were only 6.6%. That gap illustrates just how dependent the banking system had become on non-bank funding channels, a dynamic the PBOC has been trying to normalize.

What this means for investors and crypto markets

The PBOC draining 200 billion yuan through the MLF while banks simultaneously ramp up NCD issuance is a double signal. The central bank is actively pulling liquidity, and banks are feeling the pinch enough to go borrowing.

Smaller Chinese banks, the ones most reliant on NCD funding, have faced growing regulatory scrutiny over their balance sheet quality and exposure to local government debt. If wholesale funding costs rise meaningfully, some of these institutions could face margin pressure.
