China's central bank cut its one-year pledged supplementary lending (PSL) rate by 25 basis points to 1.5% from 1.75% as part of a suite of new monetary policy adjustments announced Tuesday.

The People's Bank of China expanded the scope of the PSL facility to support the construction of the "six networks," which covers water infrastructure, new-type power grids, computing power, next-generation communications, urban underground pipelines, and logistics, according to a statement on Tuesday.

Additionally, the central bank raised the quota for its sci-tech innovation and technological upgrading relending facility by 200 billion yuan to 1.4 trillion yuan, while increasing the support ratio from 60% to 100%.

Meanwhile, the quota for agriculture and small business relending was increased by 500 billion yuan to 4.85 trillion yuan, including a 300 billion yuan rise for private enterprise relending to 1.3 trillion yuan.
