The cut was timed to maintain adequate liquidity conditions in the face of ongoing capital outflows and lower short-term rates somewhat to counter their recent rise with the automatic withdrawal of significant short-term liquidity, post-Chinese New Year.

Meanwhile, it sent a clearer signal of monetary policy accommodation now that exchange rate concerns and pressures have eased compared with earlier this year.

Additional RRR cuts have been expected and needed for a while to offset sizeable yuan-depreciation fanned capital outflows since last October's RRR cut. We estimate non-FDI capital outflows stayed high at around $160 billion in December and January.

However, the central bank has until now been reluctant to deliver, preferring to use shorter liquidity provisioning or interest rate tools such as Standing Lending Facilities and Medium-term Lending Facilities instead, for fear of further aggravating RMB depreciation pressures.

Now that exchange rate concerns and pressures have eased somewhat versus the Chinese New Year, the PBOC appears to be sending a clearer signal of monetary policy accommodation.

Even before G20 finance ministers and central bank governors' calls last week, the Chinese government had been indicating that it would be adopting more expansion in fiscal and monetary policies to support growth.

December's Economic Work Conference laid out a clear easing bias for China's 2016 policy plans. We expect more detailed measures to come, including the new budget to be unveiled at the annual National People's Congress this weekend, on the monetary, fiscal and structural fronts.

As Governor Zhou Xiaochuan reiterated last Friday, there will be more policy easing to come, but the PBOC does not intend to let its currency depreciate sharply and will manage its exchange rate referencing the basket while considering dollar-yuan movements. We still see the PBOC cutting the RRR multiple times by a total 300bp cuts and cutting benchmark rates twice more (taking the 1-year deposit and lending benchmark rates to 1 percent and 3.85 percent, respectively) this year.

While benchmark interest rates were not cut on Monday, persistent deflationary pressures mean that real interest rates remain too high, pushing up corporates' debt servicing burden and risking passive monetary tightening. We maintain our view that the RMB will only be allowed to depreciate by a modest 5 percent against the US this year, leaving it at 1: 6.8 by the end of 2016.
