KYIV, June 6 - Parliament will vote Thursday on the creation of an anti-corruption court, a key condition of unlocking the country's $17.5 billion International Monetary Fund (IMF) bailout that's been frozen since last year.

Delivery of the funds has been repeatedly put on hold as Kiev struggles to enact the IMF's required reforms, which include the anti-corruption measures and raising household gas prices.

A failure to get enough votes for the anti-corruption court — something Ukrainian politicians have been fighting about publicly, and more fiercely behind closed doors — could tip the nation into deeper uncertainty and send investors running for the door.

"Should the vote fail, it will likely exclude additional IMF support for the foreseeable future while also drawing further negative attention to the government," said Maximilian Hess, a senior political risk analyst at London-based consultancy AKE Group, CNBC reported.

Prime Minister Volodymyr Groysman has threatened to resign if the vote is not passed and all IMF conditions are not met, although he has opposed the hike on gas prices.

Ukraine's central bank has highlighted IMF financing delays as "the key" risk to its financial stability, CNBC reported. The nation of 45 million has a national interest rate of 17 percent — the highest in Europe — and rates are only set to be pushed higher if help from the IMF does not materialize. Inflation, too, remains stubbornly high at 13.1 percent.

Four years after mass protests erupted to remove then-President Viktor Yanukovych from power, Ukrainians citizens and international investors are frustrated at an economy that's remained troubled and steeped in corruption. Transparency International ranked Ukraine 130 out of 180 countries in its Corruption Perceptions Index for 2017.

Ukraine restructured its debt in 2015 following its sovereign debt crisis triggered by conflict with Russia in 2014, leaving it with large annual payments to make between 2019 and 2027. Its foreign currency reserves are at roughly half the level they were before the crisis.

Meanwhile, Groysman and his finance minister Oleksandr Danylyuk have been in an open spat over the naming of appointees, with the latter having sent a letter to his G7 counterparts complaining that nepotism and political corruption continue to dominate Ukraine.

On Wednesday, Groysman asked the Rada to fire Danylyuk — who's been seen as a major reformer — for misconduct. "I am sure that lawmakers would be delighted to vote the reform-minded Danylyuk out of office," said Timothy Ash, senior emerging markets strategist at Bluebay Asset Management.

The Danylyuk-Groysman feud and a potential stricture on Ukraine's ability to sell Eurobonds the way it did last year, could cripple the country's ability to tap the private debt market for its financing needs, Hess said.

Ukraine's economy has been in turmoil ever since the Euromaidan protests in 2014 that triggered Russian annexation of its Crimean peninsula and a war with Russian-backed forces in the country's east that has engulfed 7 percent of its territory and killed more than 11,000 people.

Ukraine managed to successfully sell $3 billion in dollar bonds in 2017, helping mitigate a bit of its debt burden, but the recent sell-off in emerging markets is making borrowing costs far more expensive. The Institute for International Finance recently named Ukraine among the five most vulnerable emerging markets to a strengthening dollar and rate rises. It currently has more than $20 billion in outstanding dollar debt.

"While Ukraine maybe — emphasis on maybe — could meet its debt obligations in 2019-20, a new sovereign debt crisis is entirely possible, particularly if additional IMF support is not forthcoming," Hess said.

"Rising interest rates, the continued conflict with Russian-backed separatists in eastern Ukraine, and uncertainty around the elections and about further loans or guarantees from the EU and other Western partners mean that concerns over the sustainability of Ukraine's state debts could return rapidly."
