(Updates for market open)

Oct 29 (Reuters) - India's equity benchmarks opened

higher on Wednesday, tracking gains in their Asian peers, ahead

of the U.S. Federal Reserve's policy decision later in the day.

The Nifty 50 was up 0.18% at 25,982, while the BSE

Sensex rose 0.04% to 84,663.68, as of 9:15 a.m. IST.

All 16 major sectors advanced at open.

Most markets in Asia rose on the day, with MSCI's broadest

index for Asia Pacific stocks outside Japan up

0.5% following a fresh wave of optimism over artificial

intelligence.

The focus is also on the Fed's rate decision. Markets are

pricing in a 99.9% chance for a 25-basis-point rate cut,

according to CME's FedWatch Tool.

Lower U.S. rates typically make emerging markets such as

India more attractive to foreign investors.

Overseas investors bought Indian shares worth 103.4 billion

rupees ($1.18 billion) on Tuesday, as per provisional data,

marking their biggest single-day buying in months.
