Portugal Colonial - Oil surges on Russia tensions

The price of benchmark oil contract, Brent North Sea crude, jumped more than five percent to back above $100 per barrel after Russia rejected a ruling from the UN's top court to suspend its Ukraine offensive.

"Russia's invasion is still dictating price action... given the country's global importance in terms of supply," Interactive Investor analyst Victoria Scholar told AFP.

The fallout from the war in Ukraine could cut global economic growth by "over one percentage point" in the first year after the invasion, the OECD grouping of developed economies said in a report.

The impact "if sustained" would produce "a deep recession in Russia" and further increase global consumer price inflation by approximately 2.5 percentage points, it added.

The warning came as Russia's finance ministry said it had carried out interest payments on two foreign bonds, avoiding default for now after it was hit by unprecedented Western sanctions over Ukraine.

Central banks were also in focus with the Bank of England expected to announce a third straight interest rate rise to combat decades-high UK inflation.

The Bank of England (BoE) gives its latest rate decision at 1200 GMT, a day after the Federal Reserve lifted US borrowing costs to tackle soaring prices.

"The global economy faces elevated levels of inflation because of various factors, including from surging energy and commodity prices," noted Fawad Razaqzada, analyst at ThinkMarkets.

"While the Fed has just started its hiking cycle, the BoE is well on the way, having raised interest rates in its previous two meetings."

In Asia, Hong Kong's main stocks index closed with another massive gain, as investors pile back in after China's pledge to support markets.

The Hang Seng surged seven percent, a day after a nine-percent jump.

Another blistering surge in tech firms helped Hong Kong extend its recovery from the recent rout, while traders also cheered soothing comments on the US economy by the Fed after it lifted interest rates.

China's top economic official has vowed measures to support beaten-down markets and indicated that a debilitating crackdown on the technology sector was nearing its end.

"The statement addressed so many issues on various fronts, which is really rare," said Ding Shuang at Standard Chartered.

"Selloffs tended to be self-fulfilling partly because of the lack of response from the government," but part of the government's aim is likely to break that inertia and stabilise expectations, he added.
