PBOC Window Guidance Directs Major Banks to Cut Back Interbank Lending; Overnight Repo Rate Rebounds to 1.4%
Miles Bennett
The PBOC has told major banks to cap net interbank lending, pushing the overnight repo rate from 1.2% back to 1.4% — level with the policy benchmark — signaling that cheap liquidity is no longer a free pass.
What exactly did the PBOC do?
The central bank issued window guidance — informal verbal directives — to major lenders including policy banks, ordering them to strictly limit net lending to other banks, Bloomberg reported citing people familiar with the matter.
This means → big state banks are the main "tap" for interbank liquidity. The PBOC didn't raise rates; it turned down the tap directly.
The PBOC did not respond to a request for comment.
What has the market felt so far?
The overnight repo rate climbed from roughly 1.2% in April to 1.4%, now matching the policy benchmark rate.
The 10-year government bond yield also rebounded from 1.7% at the start of the month to 1.75%.
In plain terms = money had become too cheap and too easy to borrow; borrowing costs are now returning to what the PBOC considers "normal."
Why did cash pile up in the first place?
Corporate and household loan demand has stayed weak; credit growth has fallen to its lowest level on record.
Banks, unable to lend out funds, turned to lending to each other or buying bonds — cash churned inside the financial system instead of reaching the real economy.
This reflects a structural mismatch: liquidity the PBOC released never reached businesses and consumers; it circled among banks, pushing borrowing costs to multi-year lows.
Why not just raise interest rates?
A global energy-price shock is hitting the Chinese economy; high oil prices are suppressing both consumer and producer prices.
Several economists have pushed their forecast for the PBOC's next rate cut to 2027.
This means → the PBOC can neither cut rates (risking more idle cash) nor hike (the economy still needs support). Window guidance is a compromise — adjust the volume, not the price.
What does this mean for markets?
Markets had broadly bet that with rate cuts off the table, the PBOC would substitute loose liquidity instead. This guidance rejects that bet outright.
Banks have turned net short-term borrowers for the first time in seven months — excess liquidity is normalizing.
In plain terms = the PBOC's message is clear: the policy rate is the anchor, and easy liquidity is not an unconditional promise. Any trade built on "money stays cheap" needs reassessing.
