MANILA (Reuters) - The Philippine central bank remains vigilant on domestic liquidity and global developments, including a shift in United States Federal Reserve policy, to stem risks to the financial system, its chief said.

Monetary authorities continue to monitor "domestic liquidity to ensure there are no financial stability risks building up," Bangko Sentral ng Pilipinas Governor Amando Tetangco Jr. told reporters in a mobile text message.

Tetangco also said the central bank is closely watching effects to financial and price stability of global developments like shifts in the US Federal Reserve's policy stance, China's growth prospects and geopolitical issues.

The central bank chief's comments came after data showed Philippine inflation settled at 3.9 per cent in March, against a 4.2 per cent consensus in a Reuters poll and slower than the 4.1 per cent posted a month earlier.
