Dollar hits new highs as yields spike after Trump win

NEW YORK (Reuters) - The dollar rose across the board and hit its highest in nearly four months against the Japanese yen on Wednesday, as U.S. Treasury debt yields touched multi month highs following Republican candidate Donald Trump’s victory in the presidential election.

Prices fell on benchmark 10-year Treasury notes and 30-year bonds, pushing yields to their highest levels in 10 months, as investors expected Trump to enact protectionist trade policies that would put upward pressure on U.S. wages and boost inflation.

U.S. 30-year bond yields, which move inversely to prices, had their sharpest rise in more than five years while 10-year note yields posted their largest increase since July 2013.

Fear of rising inflation tends to erode the value of bonds, increasing yields. Higher U.S. interest rates raise the value of the dollar by making dollar-denominated assets more attractive to investors.

“Yields are driving moves and are driving everything we’re seeing in the markets, and as long as they continue to rise you’ll see dollar/yen rise,” said Kathy Lien, managing director of BK Asset Management. “Dollar/yen is getting positive support from the turnaround in U.S. stocks, positive support from the yield spreads and generally speaking we’re seeing pretty consistent price action across these different markets.”
