Adds bullet points, updates prices

LONDON July 17 (Reuters) - Geopolitical risks weighed on Wall Street on Wednesday after U.S. presidential candidate Donald Trump sounded lukewarm about defending Taiwan, sending chipmakers' shares lower and helping propel gold prices to record highs.

Futures contracts ESc1 tracking the U.S. S&P 500 equity benchmark equity index .SPX dropped by 1% after the index hit a record high in the previous session.

Shares in artificial intelligence chipmaker Nvidia NVDA.O, fell 3.1% in pre-market trading after a rocky Asian session for Taiwan's TSMC 2330.TW, which closed 2.4% lower.

The Netherlands'ASML ASML.AS, the largest equipment supplier to chipmakers, dropped as much as 7.7% in European morning trade.

MSCI's broad index of world shares.MIWO00000PUS was flat.

The tech mood soured after Trump questioned U.S. support for Taiwan in an interview with Bloomberg Businessweek, saying the closely monitored island thatChina claims as its own territory should pay for U.S. protection.

U.S. and Taiwanese officials haveclaimed for many years that a Chinese invasion of Taiwan would heavily disrupt global trade and high-tech supply chains.

Before Wednesday, markets had formed acautiously optimistic view of a second presidency for Republican property tycoon Trump, who political betting sites tip to beat incumbent Democrat Joe Biden in the November 5 battle for the White House.

"Many strategists have suggested (Trump) is bullish for equities, and I'm just not sure about that," said Benjamin Melman, global chief investment officer at Edmond de Rothschild Asset Management.

"In terms of risk premium, today the market is adding a clearer reading."

WhileTrump's plans for Taiwan remain unclear, he has already signalled reduced U.S. support for strategic allies by picking Ohio Senator J.D. Vance, whoopposes military aid for Ukraine, as his running mate.

Sterling GBP=D3 touched a year-high of $1.3032 after data on Wednesday showed the annual rate ofBritish inflation held at 2% in June against forecasts for a 1.9% increase and traders pared back their bets for a Bank of England rate cut in August.

Spot gold XAU= rose 0.2% to an all-time high of $2,473/29 per ounce on haven buying, and as increased expectations for U.S. interest rate cuts added to the pressure on the dollar.
