Iron ore is currently the bread and butter of $BHP Group Ltd(BHP.AU)$ and $Rio Tinto Ltd(RIO.AU)$ . I'm bullish for this long term as buildings and cities develop worldwide, but this demand could slump if there is a global recession. The weak china demand makes sense right now and the companies sound bullish for demand in india increasing.
I'm interested to see how BHP handles the nickel issues. This could certainly be a drag for them
