Fuel oil rose 2.13% to 5,418 yuan/tonne; the HSFO-VLSFO spread is widening again on winter bunker restocking. For scrubber-fitted owners, per-voyage fuel savings are back in the range that justifies the retrofit.

Fuel oil front-month contract closed at ¥5,349/t, surging ¥321 (+6.38%)—the week’s strongest move; concentrated restocking demand from coastal power plants and bonded bunkering tightened spot liquidity.
