Which of the following is false about the bid/ask spread on currency quotations? (Points : 3.5)

Currencies for countries with frequent political risks (i.e., the country risk of the currency is high) will have smaller bid/ask spread. The more intense the competition for the traded currency, the smaller the bid/ask spread is. The higher the inventory costs, the larger the bid/ask spread is. The larger the order costs, the larger the bid/ask spread is.
