And if we now increase imports I expect a larger global trade imbalance, which increases the supply of Dollars against other currencies, particularly the Euro, if oil prices rise further. This will affect other oil importing countries too. Although, with greater supply of the Dollar, theoretically a weakening in the Dollar should make Dollar denominated oil more affordable to consumers buying in other currencies, the empirical evidence shows no such relationship as the demand elasticities are extremely small and the volatility of oil price is usually four to five times that of the currency, completely overwhelming any currency effect.
