The People's Bank of China lent 541 billion yuan to banks overnight at 1.25% on Monday, the first operation after it made the one-day reverse repo rate its main policy rate in place of the 1.4% seven-day rate it had used as its benchmark.

The switch matters for anyone holding Chinese government bonds, borrowing in yuan or pricing loans off mainland money markets. The new anchor sits 15 basis points below the old one, and analysts at Huatai Securities have described the change as a de facto rate cut, according to Bloomberg. It also ties the central bank's main lever to the rate that banks actually trade most: overnight deals make up about 90% of repo turnover in China's interbank market, Reuters reported in August.

The central bank said the Nov. 2 operation was carried out at a fixed rate through quantity bidding and fully met the demand of primary dealers. Xinhua described it as the first operation under a revised mechanism the PBOC announced late last month.

How the PBOC's New Policy Rate Works

Under the new arrangement, the PBOC will run overnight reverse repos every working day at a fixed rate, letting banks bid for as much as they want at that price, Caixin reported. The seven-day operations do not disappear. They will be used mainly around tax deadlines and month-ends, according to Caixin.

The last seven-day operation under the old regime, on Oct. 30, was small: 15 billion yuan at 1.40%, the central bank's notice showed. On the same day, it injected 1 trillion yuan through overnight reverse repos, part of a run of daily one-day operations scheduled from Oct. 21 through Nov. 2, Bloomberg reported.

Governor Pan Gongsheng laid out the logic at the Financial Street Forum in Beijing on Oct. 19. The interbank overnight repo rate, known as DR001, had become the de facto target of monetary policy, he said, while open market operations and the official policy rate were mostly seven-day. He called that a maturity mismatch and said the PBOC would look into making overnight operations the main tool, with the overnight rate serving as the primary policy rate.

The PBOC debuted an overnight tool in late June without publishing the rate, Caixin reported; Bloomberg later said the rate had been set at 1.25%. Through the summer, the central bank leaned on the new tool more often, including a stretch in August when dealers did not use the routine seven-day facility for three straight days, Reuters reported.

What It Means for China Bonds, Loans and the Yuan

Lower and steadier overnight funding helps leveraged bond investors, who borrow short term to hold longer-dated debt. After Pan's speech, China's 10-year government bond yield stood at 1.64% and the 30-year at 2.06%, Bloomberg reported, while the overnight repo rate held at 1.26%. Overnight interbank costs had fallen below 1.3% in October, the lowest since May.

Analysts have pointed to a longer road. Michelle Lam, greater China economist at Societe Generale, told Bloomberg the PBOC should run more frequent one-day operations, while Tianfeng Securities analysts led by Liu Jie expect the overnight rate to be formally set as the benchmark anchor in the first half of 2027. The central bank has now moved faster than that forecast.

Loan pricing is the next piece. Pan said financially strong companies may choose either the interbank overnight repo rate or the loan prime rate as the benchmark for floating-rate loans, after negotiating with their banks, and that some lenders have already started using market rates. He added that the loan prime rate could remain the benchmark for loans to small businesses and individuals, and that the overnight rate could serve as an alternative benchmark for pricing bonds and derivatives.

The move runs against the trend elsewhere in the region, where several central banks have turned to rate increases this year to contain energy-driven inflation. The yuan has held firm regardless and touched a four-year high in October.

New Backstop for the Bond Market

The rate change came days after the PBOC set up a separate safety net for bond markets. On Oct. 26 it announced the Bond Market NBFI Swap Facility, which in a market-wide liquidity squeeze would let systemically important bank wealth management units and mutual fund managers borrow central bank bills from the PBOC and use them for repo financing. The cash would go toward buying eligible bonds or units of funds hit by redemptions, with the assets pledged back to the central bank.

Together, the two steps give the PBOC a price lever that matches where banks fund themselves and a backstop aimed at the fund industry. Pan has also said the central bank will issue policy guidelines for financial institutions in due course.

The overnight operations now run every working day, so the daily notice from the PBOC's Open Market Operations Office shows the policy rate and the volume banks take. Any change in that 1.25% figure would be China's first move under the new anchor.
