NEW YORK (Reuters) - Sterling jumped alongside gold, while stocks and the U.S. dollar fell on Tuesday after Britain called a snap election for June, adding to investor concerns over geopolitical instability.
The British pound rallied as much as 2.7 percent against the U.S. dollar to hit its highest level since early October after British Prime Minister Theresa May surprised markets by calling for an early parliamentary election.

A poll giving centrist independent Emmanuel Macron the lead ahead of the first round of France's presidential election boosted the euro. Polls have for months shown far-right leader Marine Le Pen and Macron qualifying this Sunday for the May 7 run-off, but it remains a contested, four-way vote with conservative Francois Fillon and far-left candidate Jean-Luc Melenchon.
The possibility of U.S. military action against North Korea remained on investors' minds, as well.
On Wall Street, disappointing quarterly results from corporate heavyweights Goldman Sachs and Johnson & Johnson dragged major stock indexes lower.
Investors are also concerned that the recent flaring of geopolitical tensions has shifted focus away from expected business-friendly reforms in the United States, seen as the fuel for the U.S. equity rally that peaked in early March.
"We seem caught in the back and forth in the uncertainty around the (Trump) administration’s plans," said Rick Meckler, president of investment firm LibertyView Capital Management in Jersey City, New Jersey.

The pound rallied as British Prime Minister May called for an early election on June 8, saying she needed to strengthen her hand in divorce talks with the European Union.
"The way the market is reading it, it is viewed as something that creates a more stable political outlook for Brexit to happen, which in itself is viewed as a positive," said Alvise Marino, FX strategist at Credit Suisse in New York.
Weighing on the dollar were also bank comments: while Deutsche Bank said the surprise UK election call is a "game-changer" for sterling, Goldman Sachs analysts exited long dollar bets against the euro and pound, citing a pickup in global growth.
The dollar index .DXY fell 0.77 percent, with the euro EUR= up 0.85 percent to $1.073.
