Well-established traders marketing ore from India to China were aff ected when an export ban was introduced in India. Why did some well-established traders fail to heed the warning signs? Specific answers might relate to misjudgements about FMG’s likelihood of ramping up production, or shifts in the domestic Indian steelmaking raw materials supply/demand balance, or northeastern Chinese mills’ appetite for low grade ore. But the wider point is the innate difficulties we experience accurately assessing the likelihood and effect of high probability/low impact and low probability/high KOTC Copyright: impact risks.
