NEW DELHI: Asia's gasoline crack edged up on Tuesday, snapping a three-day losing streak, after analysts estimated a decline in U.S. inventories.

The crack was at $7.50 a barrel, the lowest since early July, up from $7.30 in the previous session.

A Reuters poll estimated that U.S. stockpiles of gasoline fell by about 1.7 million barrels last week, indicating positive demand sentiment. In physical markets, demand for 92-octane gasoline held firm as Unipec and PTT purchased two cargoes each.

Asia's naphtha crack also added gains for a second straight day, while the prompt inter-month spread stabilised at $1.75 after flipping into contango on Friday.

The crack rose to $116.63 a tonne from $111.30 in the last session. Oil prices rose on Tuesday, extending sharp gains on a bullish demand outlook as Mexico suffered a big production outage and U.S. regulators issued their first full approval for a COVID-19 vaccine.
