BEIJING, Aug 27 (Reuters) - China has been so surprised by the global reaction to its currency devaluation that it is likely to keep the yuan on a tight leash in the near-term to head off a currency war that could spark a broader financial crisis, policy insiders say.

Internal calls for the yuan to weaken by up to 10 percent since the Aug. 11 devaluation have faded as top leaders worry that market fears of such a move could fuel further capital outflows, signs of which have intensified in July and August.

Government economists and policy advisers say the People's Bank of China (PBOC) will now try to stop the yuan weakening much past 6.5 per dollar, which is 4.5 percent below its pre-devaluation levels. On Thursday morning, the yuan traded as low as 6.4162 per dollar.

"The global reaction was bigger than expected," said a senior economist at the cabinet's think-tank.

"The global economy is very fragile  competitive currency devaluations could in turn affect China's own economy - undermine its exports and investment."

Indeed, when cutting interest rates and bank reserve requirements on Tuesday, the PBOC said currency fluctuations had caused a shortfall in liquidity.

That was seen as a signal that capital outflows had accelerated since the devaluation as market investors feared China would drive the yuan lower.

An influential economist at a top government think-tank said policymakers may have underestimated the global impact from the yuan devaluation, which happened when jitters about China's slowdown had intensified due to a stock market plunge.

"You chose the timing as the economy weakened and the stock market plunged, sending out a wrong signal to foreign countries that you want to spur the economy through devaluation and leading to competitive devaluations," said the economist, who last month discussed policy issues with Premier Li Keqiang.

"This put us on the defensive; it looks like China is the trigger."

Premier Li was quoted by state television as saying on Tuesday that there was no basis for continued depreciation.

China ran down its foreign exchange reserves by $340 billion from mid-2014 to the end of July, which some economists see as a proxy measure of outflows. No data is available yet, but analysts think the pace quickened after the devaluation.

The PBOC will count on its war chest of FX reserves - still the world's largest at $3.65 trillion - to defend the yuan from selling pressure as foreign investors flee the country and domestic investors convert yuan into dollars.
