(Sharecast News) - Asia-Pacific markets were primarily in the red on Monday, as investors digested key economic data from China.

The People's Bank of China maintained its medium-term lending facility rate at 2.5% on CNY 182bn, aligning with expectations.

China also reported a 3.7% increase in retail sales for May, surpassing the anticipated 3% growth from a Reuters poll.

However, industrial output grew by 5.6% year-on-year, missing the expected 6% rise, while fixed asset investment increased by 4%, slightly below the 4.2% forecast.

"China's monthly activity data for May on Monday are likely to reveal an uneven economic recovery," said TickMill market analyst Patrick Munnelly earlier.

"Industrial output is forecast to slow to 6.4% from 6.7% in April, retail sales to pick up to 3% from 2.3%, and urban investment is seen steady.

"Unemployment and house prices will also be watched."

Munnelly added that the PBoC was expected to hold its one-year medium-term lending facility rate at 2.5% on Monday, continuing to prioritise currency stability despite growing calls for older stimulus measures to combat deflationary pressures and spur domestic demand.

"China is also likely to leave its one-year and five-year loan prime rates unchanged at 3.45% and 3.95% respectively on Thursday."

China data, monetary policy in focus

In economic news, China - the world's second-largest economy - released key economic data for May, presenting a mixed picture of its recovery.

Retail sales outperformed expectations, growing by 3.7% year-on-year, surpassing the 3% rise anticipated by a Reuters poll of economists.

That suggested resilient consumer spending despite broader economic challenges.

However, other critical economic indicators fell short of forecasts, as industrial output increased by 5.6% compared to the same period last year, below the predicted 6% growth.

Similarly, fixed asset investment rose by 4% year-on-year, slightly missing the 4.2% projection.

The urban unemployment rate remained steady at 5% in May, consistent with April's rate and marking a 0.2 percentage point improvement from May last year.

In monetary policy, the People's Bank of China maintained its one-year medium-term lending facility rate at 2.5% on CNY 182bn (£19.8bn) of loans, aligning with market expectations.

The central bank also injected CNY 4bn through seven-day reverse repurchase operations, keeping the seven-day interest rate unchanged at 1.8%.
