SE Asia Stocks-Fall tracking broader Asia; global tensions weigh

* Sentiment hit amid tensions in Saudi Arabia, Brexit talks

* Singapore falls ahead of September inflation data

* Indonesia's central bank expected to hold rates steady

By Rashmi Ashok

Oct 23 (Reuters) - Southeast Asian stock markets slipped on

Tuesday, tracking broader Asian markets as a lacklustre

performance on Wall Street, rising tensions over Saudi Arabia's

diplomatic isolation and Brexit talks dampened investor

sentiment.

Nervousness on Wall Street ahead of the U.S. earnings season

and pressure from world leaders on Saudi Arabia to disclose

details on the killing of journalist Jamal Khashoggi weighed

heavily on markets.

The previous session's rally on China's promise to lend

support to companies and tackle market volatility was cut short,

with the MSCI's broadest index of Asian shares ex-Japan

shedding 0.4 percent.

Singapore stocks slumped 0.9 percent, with

real-estate stocks like City Developments Ltd falling

1.9 percent and CapitaLand Ltd losing 1.6 percent to

drag the index.

The city-state's inflation data for September is due later

in the day, and annual all-items inflation in September is

expected to edge up to a 16-month high, a Reuters poll showed.

September's inflation data comes close on the heels of

Singapore's central bank's move to tighten monetary policy for

the second time this year on the likelihood of steady expansion

of economic growth.

Indonesian shares traded near flat ahead of Bank

Indonesia's (BI) meeting where policymakers are expected to hold

its key interest rate, according to a Reuters poll.

Earlier this month, BI Governor Perry Warjiyo indicated a

possible rate hike ahead of the U.S. Federal Reserve's December

meeting, to avoid "drastic" capital outflows.

Malaysian stocks continued their decline and were on

track to fall for a fourth consecutive session. Electricity

generator Tenaga Nasional Bhd lost 2.2 percent and

industrial conglomerate Sime Darby Bhd shed 2.1

percent.

The Philippine index traded lower, with banking

stocks dragging the index. Metropolitan Bank & Trust Company

fell 1.1 percent and sector heavyweight BDO Unibank Inc

lost 0.2 percent.

Among stocks which lost was real-estate conglomerate Ayala

Land Inc which fell 1.5 percent.

Vietnamese shares fell 0.9 percent with losses across

all sectors, particularly banking and real-estate. Joint Stock

Commercial Bank for Foreign Trade of Vietnam fell more

than 1 percent and Vietnam Prosperity Joint Stock Commercial

Bank fell 3.4 percent.

Markets in Thailand were closed for a local holiday.
