Chinese iron ore futures reclaimed the 700 yuan line on September 30, even as the underlying steel demand data deteriorated at an accelerating pace — a divergence that SMM data suggests will resolve firmly to the downside after the National Day holiday.

The DCE most-traded contract closed at 702.5 yuan/mt, up 0.50%. Qingdao port spot prices rose 2 yuan across all grades except IOCJ, which held flat. Port spot indices told the same story: 65% Fe fines up 2 yuan, 61% Fe up 1 yuan, and 58% Fe unchanged.

The demand data points the other way, and with increasing force. Daily average hot metal output across 242 steel mills fell to 2.3882 million mt, down 6,100 mt week-on-week. The blast furnace operating rate stood at 88.57% and capacity utilisation at 88.15%.

The trajectory leaves little ambiguity. Hot metal output has traced a steady decline from its September 2 peak of 2.4080 million mt to 2.4028, then 2.3991, then 2.3943, and now 2.3882 million mt. That is four consecutive weekly declines totalling 19,800 mt off the peak. The last three drops have widened progressively — from 3,700 mt to 4,800 mt to 6,100 mt. Demand is not bottoming. The contraction is accelerating.

SMM has now issued explicit forward guidance. With mills loss-making, some report they will draw up maintenance plans in early October, and overall hot metal output may fall markedly. Maintenance-related losses are projected to reach 1.6839 million mt next week, a further increase of 55,100 mt. That sets up the first post-holiday hot metal print to potentially be the largest decline of this cycle.

Mill margins are moving the same direction. The average loss on imported ore widened from 5.08 to 6.12 yuan/mt, and SMM expects further deterioration.

One basis tension deserves mention. That margin calculation references September 29 spot and freight costs, whereas on September 30 port spot recovered and freight fell another 4–6% — both of which mechanically repair margins. The first post-holiday print could therefore recover some ground.

Freight collapse reshapes Brazilian economics

Two structural shifts sit beneath the daily noise. The first is the accelerating collapse in capesize freight rates. The C3 route (Tubarão–Qingdao) has slid from $43.06 to $40.26, a two-day fall of 6.5%. The C5 route (West Australia–Qingdao) has dropped from $16.36 to $14.13 — a steeper two-day decline of 13.6%.

The implications for seaborne supply are direct. The argument that high Brazilian freight was curbing shipments is now void. With every dollar off the C3 route, the commercial case for Brazilian tonnage to return to the market strengthens, and the room for Brazilian supply to recover only grows.

The second shift is on the coke side. Coke oven capacity utilisation rose to 75.0% this week, up 2.3 percentage points, with Shanxi province at 72.7%, up 2.8 points. That recovery is the practical precondition for the rumoured first round of coke price cuts — and currently the only thread pointing toward any repair in steel mill input economics.

What October decides

On balance, the pre-holiday bounce in ore prices is sentiment repair and does not change a soft and choppy fundamental picture. For iron ore shippers and capesize owners, the combination of falling hot metal output and recovering Brazilian freight economics points to more cargo chasing weaker steel demand — a bearish mix for both commodity prices and vessel earnings.

The first trading week of October turns on two variables: how large the hot metal decline actually proves to be, and whether the coke price cut lands. The first sets the slope of the decline. The second decides whether it has an end.
