Singapore shares opened flat on Wednesday, tracking overnight losses on Wall Street as market participants remained cautious about the momentum of the AI-driven rally and awaited fresh signals from the U.S. Federal Reserve.

The STI, a key benchmark for the Singapore Exchange, rose marginally in early trade by 0.02%, or 1.11 points, to open at 5,343.360.

Sentiment remained subdued after the tech-heavy Nasdaq Composite led overnight losses on Wall Street, declining 1.16% as semiconductor stocks came under pressure despite stronger-than-expected earnings from South Korean chipmaker Samsung Electronics (KRX:005930). The broader S&P 500 slipped 0.45%, while the Dow Jones Industrial Average fell 0.25% at market close on Tuesday.

Investors are awaiting the release of the Federal Reserve's June meeting minutes on Wednesday, the first chaired by Kevin Warsh, for additional insight into the interest rate outlook ahead of the Federal Open Market Committee's (FOMC) July 28-29 policy meeting.
