LONDON - Asian spot prices for liquefied natural gas (LNG) fell after six straight weeks of gains as more supply emerged and buyers aggressively revised down bids for December shipments.

Spot Asian LNG prices for December delivery fell to $8.90 per million British thermal units (mmBtu), with the bid-offer spread widening as sellers maintained high asking prices for now.

According to one Singapore-based trader, bids for December deliveries in northeast Asia are at $8.50 per mmBtu with offers at $9.50 per mmBtu, contrasting with a week ago when buyers were more closely aligned with sellers.

November prices are assessed at $8.55 per mmBtu.

"This week Taiwan, China and South Korea returned to the market after their holidays, they are willing to buy but not willing to pay these levels," he added.

With more supply emerging from Russia, Angola, Indonesia, Oman, Australia and the United States, sellers were expected to revise price pitches more in line with buyer expectations, several sources said.

Expressed as a percentage of Brent, spot Asian LNG prices are at around 17 percent, exceeding oil-linked, long-term contract levels.

That incentivises Asian buyers to request more supply under 25-year supply deals, reducing demand for spot LNG.

Malaysia's state-run Petronas sold a free on board cargo from Australia's Gladstone LNG plant to Shell, sources said. Petronas also sold a separate shipment for November delivery from its Bintulu LNG plant to Taiwan's CPC for an estimated $8.70-$8.80 per mmBtu, they said.

Cheniere's Sabine Pass liquefaction plant on the U.S. Gulf Coast offered more volume for November and December, one trader said, after bringing its fourth production unit on stream.

Angola's export facility this week sold a cargo via tender to British oil major BP, whose British Emerald tanker is currently loading supply at the plant.

Italian oil major Eni sold a cargo from Indonesia's Bontang plant, potentially to an oil major, a trader said, although details could not be confirmed.

Russia's Novatek-led Yamal export facility in the Arctic is due to ship two cargoes in November and four in December, potentially via spot market tenders, more than the market had expected from the project's start up phase.

Indonesia's Tangguh plant launched a tender offering up to two shipments per month in 2018.

A cargo is also being offered by Oman for December delivery via a closed tender, a trader said.

Commodity trader Trafigura is expected to carry out several reloads from the Gate import terminal in the Netherlands, sources said.

It has chartered the Hoegh Giant, currently moored at Gate, and the Adam LNG tanker, scheduled to lift volume on Oct. 24, shipping sources said.

Wide prices spreads with Asia are making European reloads more attractive. Several exports from France's Montoir terminal have been sold to Brazil. Spain's first reload in 14 months may take place on Oct. 12-13 from the Cartagena facility, according to Enagas data.

On the demand side, some price-sensitive Indian buyers cancelled purchase plans. A tender launched by India's GSPC for two cargoes appears to have gone unfilled, traders said. Gail India, however, may have purchased supply under its three-cargo tender for delivery across November and December.

The status of Indian Oil Corp's LNG tender could not be verified.

Mexico purchased a cargo this week for mid- to late-October delivery at the Pacific port of Manzanillo, traders said. One pointed to Shell as the likely supplier.
