Policymakers seem happy to keep them that way, defying expectations of a move and instead waiting as long, and pulling as many alternative levers as possible, to delay the first of what economists think could be many as six RRR cuts this year.
The People's Bank of China has opted for open market operations to inject short-term liquidity into the financial system in recent weeks, helping to keep credit flowing as growth in the world's second-biggest economy hits a sticky patch due to weak global demand.
Beijing is reluctant to give the green light to another bout of big bank lending while it is still gauging how deep or shallow the latest economic downturn is, especially as policymakers are still trying to soak up the credit excesses and inflationary pressures spawned by a 4 trillion yuan (401 billion pound) economic stimulus program in 2008.
"They are keen to hold things steady. I think they are poised if they have to do something, but I don't think they feel the shock is bad enough, yet," said Tim Condon, head of research at ING in Singapore.
"The fourth quarter was a bad quarter but I don't think it was bad enough to make them really scared. If it gets a lot worse, I'm sure we'll see them moving. It's tough in Q1... the economy is going to be more difficult than usual. "
Difficult yes, but the intensity of the economic headwinds are nowhere near as severe as in the 2008 financial crisis.
Which helps explain why the central bank used two 14-day reverse repurchase operations just ahead of the New Year holidays to meet surging demands for cash.
The 352 billion yuan injected into the system was roughly equivalent to the 350-400 billion yuan delivered by the 50 basis point RRR cut announced on Nov 30, the first in three years. That move took the rate down from a record 21.5 percent.
Investors believe the central bank also conducted reverse repos with individual banks.
"It seems that the PBOC wants to signal its prudent stance. It does not want the market to get a wrong idea that the new year means more credit," said Wei Yao, China economist at Societe Generale in Hong Kong.
"And they are more willing to accept more slowdown and refrain themselves from over-stimulating the economy — basically the same mistake they made years ago."
Uncertain Outlook
The reserve ratio cut for big banks has been followed by a gradual relaxation of some controls on credit at smaller regional institutions in recent months to support the slowing economy.
Meanwhile, the deep-pocketed government has focused more on cutting taxes and red tape for the small businesses that provide about 75 percent of the jobs in China.
By opting for reverse repos — through which the central bank injects cash by buying securities from banks and then selling them back at a set date — policymakers get more time to judge policy while faced with uncertain economic evidence.
Injecting liquidity via reverse repos also helps smooth out volatility in cash demands without spooking the market and sending a confusing signal on a potential policy shift.
"It's a flexible tool, you can correct it in the afternoon if you made mistakes in the morning. But if you make a mistake in RRR, it could cause a big market impact," said Gao Shanwen, chief economist at China Essence Securities in Beijing.
The central bank's caution is justified, with many uncertainties on the horizon, such as whether Europe can muddle through its debt crisis, if the U.S. recovery can gain traction and whether inflation is reignited if commodity prices rebound.
The government is due to release inflation and trade data this week but some of the numbers may be distorted by the timing of Lunar New Year, which was in January this year and in February last year. During the week-long celebrations, factories shut or run at half speed.
In March, the government will release combined factory output, investment and retail sales data for January and February to smooth out seasonal distortions.
Gentle Easing
Few analysts believe the central bank will cut interest rate cuts this year, with annual inflation staying stubbornly higher than the one-year deposit rate of 3.5 percent.
However, it faces limited options but to reduce RRR further to help offset an expected decline in capital inflows that will put strains on its ability to generate enough money supply to support economic growth, analysts say.
