SINGAPORE, Feb 12 (Reuters) - Asia's gasoil margin clung to broadly steady levels of about $20 per barrel on Thursday, while the market continued to eye mixed sentiment regarding supply into March.

Trading momentum was thin in the Singapore spot market, with cash differentials for 10ppm sulphur gasoil GO10-SIN-DIF rangebound from the previous session.

The market structure for gasoil also held steady at a backwardation of over $1 for the prompt months.

For now, inventories in Singapore edged higher, with combined gasoil and jet fuel stocks breaching 9 million barels for the first time in 10 weeks.

Meanwhile, jet fuel market timespreads rebounded in volatile trading, after weakening in the previous session. A trade also emerged in the spot window, supporting the cash premium on Thursday.

The regrade spread JETREG10SGMc1 closed at a discount near 60 cents per barrel, LSEG data showed.
