Prince Harry wore his banker blues earlier today for a fundraising event held at the BGC Partners offices in London. Harry manned the phones for the better half of his morning and closed out a deal worth 18 billion euros that put him in the world record books. Harry beat out his brother, Prince William, who set the previous record trade of 14 billion. The landmark exchange was part of a philanthropic memorial celebration honoring the 658 BGC employees who lost their lives on 9/11. Harry's participation also raised money for his own organization, Sentebale, which was one of the 29 charities benefiting from the morning's fun. The prince was joined by his cousins recent Goldsmiths college graduate Princess Beatrice and Princess Eugenie and their mother, Sarah Ferguson, as well.
