Investopedia explains 'Letter Of Guarantee'
A letter of guarantee often helps firms conduct business with parties they would never normally get the chance to deal with. Many suppliers will often choose to do business with customers that have a letter of guarantee because it eliminates the risk that they will not receive the appropriate payment for the goods that they are selling.
Additionally, call writers will often use a letter of guarantee when the underlying asset of a call option is not held in their brokerage account.
