A Derivatives Market With No Physical Metal Underneath
SGX doesn't set an iron ore price the way the LME sets metal prices. Its AsiaClear swaps and futures are cash-settled against independent index providers — Platts/S&P Global, Fastmarkets MB, TSI — who survey actual physical cargo deals. SGX is where that index gets hedged, not where it's created.
Why Singapore, of All Places
Singapore is neither a major producer, unlike Australia or Brazil, nor the dominant buyer. That neutrality, paired with English common-law contract enforcement and an existing deep shipping and trade-finance industry, made it trusted middle ground for miners and Chinese steel mills alike.
Miners on One Side, Steel Mills on the Other
Vale, Rio Tinto, BHP and Fortescue sit on the supply side; Chinese steel mills, which buy the overwhelming majority of globally traded iron ore, sit on the demand side. SGX iron ore volumes are, in effect, a live bet on Chinese steel output and construction activity.
The Grade Problem
Iron ore can't have one clean spot price the way gold or copper do, because ore varies hugely by iron content and impurities like alumina, silica and moisture depending on where it's mined. Pricing had to evolve around standardised index benchmarks — commonly 62% Fe fines — rather than a single uniform commodity grade.
SGX's iron ore derivatives market barely existed as a serious global benchmark before around 2009 — within roughly a decade it was trading a multiple of the world's entire annual seaborne iron ore volume in derivatives alone, almost entirely on the strength of Chinese demand.
