NEW YORK, Oct 7 — Stock markets firmed yesterday with the Nasdaq and S&P 500 hitting record highs in the United States, as oil prices retreated on easing supply worries, which helped temper concerns about rising government borrowing costs.

On Wall Street, the technology-focused Nasdaq index advanced 0.5 per cent to a new high, coming off a record set on Monday driven by AI enthusiasm.

The S&P 500 also hit a new record after rising 0.6 per cent.

The brisk trading in New York stoked European stock markets, after gains across most Asian equity markets.

Oil prices were subdued as Gulf exports inch back toward pre-war levels, with the international benchmark Brent North Sea crude closing just above the psychological level of US$100 (RM408) a barrel.
