亚洲石脑油/汽油-石脑油10月购买充足;汽油裂缝超过1年高点

Updates with more details in paragraph 13

SINGAPORE, Aug 22 (Reuters) - Asia's naphtha markets recorded a slew of buying activity for October spot cargoes, though traders were grappling with talks of slightly tighter supply expectations going into next month.

Naphtha's refining margins NAF-SIN-CRK gained slightly from last week, closing at around $79.5 per ton on Friday.

A flurry of procurement from regional importers were done through the week and mostly at higher discussion levels from before, against a backdrop of slightly tighter fundamentals and steady demand.

October deals done by South Korea's petrochemical majors were in the range of small premiums of $2-$4 per ton to premiums of more than $15 per ton to CFR Japan prices for mostly October deliveries, depending on the grade.

Meanwhile, buying from two key southeast Asian importers were at slight discounts to flat for October deliveries to CFR Japan quotes.

A major Taiwan buyer also bought at least one cargo for October delivery at single-digit discounts to CFR Japan quotes.

Margins for producing most petrochemical derivatives remain positive, be it aromatics or olefins, encouraging the high run rates and firm naphtha demand, several trade sources said.

Supply-wise, sentiment was mixed as front-month markets looked slightly tight given a narrower arbitrage west-east price spread — averaging $20 per ton — and limited freight cost fluctuations week on week.

However, the arbitrage situation could change again if Asian markets stayed firm.

For gasoline, three cargoes for first-half September loading from Asia were sold to key buyer in the Americas region, though further details could not be confirmed.

Expectations on supply were mixed across the board, though most traders were of the consensus that regional demand is still firm.

Octane-92 gasoline refining margins GL92-SIN-CRK closed at more than a one-year high of around $11.9 a barrel, extending gains since early week.

On the Asian buying front, Taiwan's CPC Corp is seeking up to 250,000 barrels of octane-95 alkylates for delivery between September 20 and October 15.
