TC12 WCI MR: FSD model accuracy continues as record-tight tonnage and improving arbs drive rates higher

WCI MR vessel supply in the seven-day ahead window stands at just 4 ships against a 90-day moving average of 17, 13 below average and the tightest prompt reading since April. The Freight Supply and Demand (FSD) model has been tracking this market with exceptional accuracy. It turned neutral in the third decade of July, correctly anticipating the stabilisation after the June and early July selloff, and flipped to bullish in the middle of last week as the tightening in tonnage availability began to accelerate.

The model now forecasts rates to firm from WS 205 to WS 210 into the 9 to 18 August load window. Incremental demand has turned positive, adding 2 cargoes of demand to the picture. Every input is aligned: tight vessel supply, positive incremental demand, bullish model, and supportive geopolitical tailwinds.

The rate progression in physical fixtures over the past week confirms the rally is already underway. Sea Phoenix I fully fixed loading Sikka for South Africa at WS 230 for a 4 August laycan. Ardmore Purpose fully fixed loading Sikka for South Africa at WS 250 for a 10 August laycan. Ps Roma fully fixed loading Sikka for South Africa at WS 277.5 for a 14 August laycan, carrying gasoline.

The step-up from WS 230 to WS 277.5 across three successive South Africa fixtures in less than a week illustrates the strength and pace of the rally. Vesta fully fixed loading Sikka for Port Sudan at $1,400K for an 8 August laycan, and Sea Runner went on subjects loading Mumbai for Japan at WS 215 for a 12 August laycan, confirming TC12 is indeed moving higher.

The arb picture has remained supportive even with the freight rate recovery and is providing a solid demand foundation that should sustain the rally higher. Sikka to La Plata diesel is the standout arb at +$8.60 cpg in August, and remains open into Q4, providing a persistent medium-term demand pull from South America. Sikka to Durban diesel is firmly open by +$5.40/bbl in August, the widest margin on this route in months. Sikka to Dar-es-Salaam diesel is negative in August at -$2.60/bbl but approaches breakeven by October and turns marginally positive in November. Sikka to Singapore diesel remains shut across all forward months.

The broader macro context reinforces the WCI MR bullish outlook. The same geopolitical dynamics that are driving USGC product demand are simultaneously redirecting global product demand toward WCI as the alternative supply origin for EoS destinations. This structural demand shift is not a short-term phenomenon: the La Plata and Durban arbs are open well into Q4, indicating sustained forward demand especially as the Iran conflict continues.

With prompt supply at only 4 MRs against a 17-ship average, the FSD model turning increasingly bullish, incremental demand positive, arb margins improving, and a fixture programme that has already repriced from WS 230 to WS 277.5 in just a week, TC12 is in the early stages of a sustained rate recovery.

The model called the bottom correctly and is now pointing higher. Owners should push firmly above last done levels. Charterers covering the 9 to 18 August window should act quickly; waiting will only mean covering at higher levels.
