Rising expectations that some of the world’s major oil producers will agree to production cuts appeared to steady oil prices on Monday.

But as the coronavirus continues to fan out across the globe, sapping economic activity, analysts were doubtful that a cut in production of as much as one million barrels a day would be enough to stem a weekslong slide in prices.

Officials from the Organization of the Petroleum Exporting Countries and Russia are expected to meet in Vienna this week to try to halt plunging oil prices, which sank about 14 percent last week alone. The spreading coronavirus epidemic is cutting into demand for oil and weakening OPEC’s clout, but the meeting will still be watched closely by market participants because countries representing roughly half of world oil supplies will be present.

Hopes that the gathering will lead to new and deeper production cuts helped lead to price rises on Monday, ending last week’s slide. Brent crude, the international benchmark, rose by about 4 percent to $51.68 a barrel.
