US copper widens premium to London benchmark

By Caroline Valetkevitch

NEW YORK, July 9 (Reuters) - Major stock indexes rose on

Wednesday as Nvidia ( NVDA ) climbed to a $4-trillion valuation, while

the dollar was little changed and the euro edged lower, as U.S.

President Donald Trump issued final tariff notices to seven

minor trading partners.

At the same time, the Trump administration edged closer to a

deal with its biggest trading partner, the European Union.

On Tuesday, Trump broadened his trade war, announcing he would

impose a 50% tariff on imported copper. The move sent U.S.

copper prices soaring and U.S. stock prices lower. He also said

he would soon introduce levies of up to 200% for

pharmaceuticals.

U.S. copper futures on Wednesday widened their premium to the

London benchmark.

"Certainly President Trump and the administration have shown

a willingness to change course, and what's on the table today

doesn't necessarily mean it will be on the table tomorrow," said

Oliver Pursche, senior vice president at Wealthspire Advisors in

Westport, Connecticut.

"Investors I think are ignoring that noise, and the reason

they're ignoring that noise is that the greatest fear of the

tariffs was they were going to create a significant amount of

inflationary pressure and economic disorder, and it hasn't

happened on a broad basis," he said.

Investors are awaiting further developments in Trump's trade war

in the coming days, after he told 14 nations on Monday they will

face sharply higher tariffs from a new deadline of August 1.

Helping U.S. stocks, artificial intelligence leader Nvidia ( NVDA )

notched a market capitalization of $4 trillion, making

it the first public company in the world to reach the milestone.

The Dow Jones Industrial Average rose 139.86 points, or

0.31%, to 44,377.77, the S&P 500 added 25.30 points, or

0.41%, to 6,250.83 and the Nasdaq Composite rose 152.17

points, or 0.75%, to 20,570.63.

Investors have been concerned that higher tariffs could increase

inflation and slow economic growth.

U.S. stocks stayed higher after minutes from the Federal

Reserve's June 17-18 meeting showed only "a couple" of officials

at the meeting said they felt interest rates could fall as soon

as this month.

Most policymakers remained worried to some degree about the

inflationary pressure they expect to come from Trump's use of

import taxes to reshape global trade.

MSCI's gauge of stocks across the globe rose

3.92 points, or 0.43%, to 923.23. The pan-European STOXX 600

index ended up 0.78%.

The dollar index, which measures the greenback against a

basket of currencies, eased 0.03% to 97.52, with the euro

down 0.07% at $1.1716. Against the Japanese yen, the

dollar dipped 0.18% to 146.28.

Japan, which depends on exports, stands out among major U.S.

trading partners as being the farthest from reaching a trade

deal with Washington.

U.S. Treasury yields dipped. The yield on benchmark U.S. 10-year

notes fell 7.5 basis points to 4.342%, from 4.417%

late on Tuesday.

European government bonds were little changed, with the

benchmark 10-year German yield at 2.637%.

U.S. crude rose 5 cents to settle at $68.38 a barrel.
