China's growing liquidity crisis has been drowned out by the frenzy over the US Federal Reserve's taper talk but spiking inter-bank rates have catapulted it to the forefront of markets' concerns.
The People's Bank of China edict was its first official comment since China's libor rate hit the highest levels since 2003 last week.
Fears over the cash squeeze have intensified worries about China's economic slowdown, pushing the benchmark Shanghai Composite Index under the 2000-point support level on Monday to be 3.54 per cent lower at 1999.71 in late trading.
IG market analyst Evan Lucas said the Chinese central bank could be starting to change its hawkish stance for the first time since last September, with some reports suggesting it is looking to fine tune monetary policy.
"Lending between Chinese banks has been heating up for months as the central government cracks down on shadow banking and…the huge amount of illegal capital inflows that have made credit in China easy," Mr Lucas said.
"Some are suggesting that the current state of affairs in China is very similar to that seen in the US pre-GFC.
"Leverage was cheap and easy, investors and business leaders alike snapped up credit with glee and high leverage levels were king – then it collapsed. Is China in a similar state of affairs?"
If the ASX was to find its feet again this year, cyclical stocks would need positive leads from China, he said.
