Thanks for your response.
As you agree with my teacher, I see those two sentences match each other.
I've taken out this sentence in question from a longer article so I had some more information to imagine further from. (Sorry if my mere imagination caused unnecessary confusion)
Let me simplify my question:
Is the original sentence grammatically good to mean the same as the two sentences?
One reason why I don't feel clear is that I've always learnt the word "risk" should be followed by the preposition "of".
And "in" makes me think of the circumstances in which the merchants have to face the risk. That way it doesn't seem to be clarified what the risk is...
