The first step is to determine the genuine effect of the currency or commodity swing on the supply chain. Although a business might be based in a certain country and affected by the currency swing, it is likely that part of the cost is based in another currency. For example, sourcing from a Swiss supplier (with prices set in Swiss francs) would obviously be costly in today’s climate. On deeper investigation, however, the business might find that its supplier is sourcing a proportion of its raw materials and subcomponents from a country in Europe and paying for them in euros. Knowledge of this could give the business some room to renegotiate costs and protect its profit margin.
