KIEV, Nov. 9 - President Petro Poroshenko said Wednesday he hoped the United States would continue to support Ukraine in its stand-off with Russia following the victory of Donald Trump in the U.S. presidential election.

"The President looks forward to a continuation of U.S support in two important areas: Ukraine's fight against Russian aggression ... and also assistance in the realization of major reforms," Poroshenko was quoted by Reuters as saying in a statement.

Investors dumped Ukraine's sovereign bonds on Wednesday, fearing that Trump's election victory will swing U.S. foreign policy towards Russia, leaving Kiev isolated between the two world powers and wrecking its fragile economy, according to Reuters.

The dollar-denominated bonds fell across the curve, shedding two to three cents. Ukraine's average yield premium to U.S. Treasuries rose as much as 84 basis points, significantly underperforming the broader emerging debt index.

Trump's ascent in recent months and the perception he is favorably inclined towards Russian President Vladimir Putin has raised unease among investors, who last year agreed to write off a chunk of their Ukraine holdings as part of an International Monetary Fund-led bailout.

Many fear that Trump, who has said he was "honored" to have been complimented by Putin, will soften the U.S. stance on the Kremlin or even ease the sanctions put on to punish Moscow for annexing Ukraine's Crimea and for fomenting unrest in the country's east.

"It's a case of 'watch this space' but the market is probably right to increase the risk premium on Ukraine because that's one area of foreign policy where we will probably see some adjustment," said Kieran Curtis, a portfolio manager at Standard Life Investments.

Trump has hinted he might recognize Crimea's annexation and hold back from aiding the Baltic states should they be attacked by Putin, even though they are members of U.S.-led NATO. As a result, emerging market investors braced for a Trump win by buying Russian assets.

"There is clearly now a risk to sanctions, and they will probably not be tightened, and there is a risk of them being relaxed," said Evghenia Sleptsova at Oxford Economics.

She considers Ukraine's bonds, now worth 93 to 98 cents on the dollar, overvalued. Aside from Trump risks, she said Kiev's European allies were likely to be preoccupied with Brexit and upcoming elections in France and Germany.

"This is really going to be a hard year for Ukraine ... if it wasn't priced in already, without a doubt that will be priced in now." (rt/ez)
