Morning Coffee: 23 year-old M&A banker ruins career in one move. John Cryan, miser

However successful and sparkling your investment banking career, you are only one stupid email away from disaster. This is the lesson to be learned from the sorry story of Justin Kwan.

Kwan is the (ex) Barclays analyst who last week sent a facetious email to incoming interns on the bank's 'power team.' One week later, Kwan has reportedly disappeared from Barclays. Worse, Kwan was reportedly on the verge of leaving Barclays for private equity fund Carlyle, but Carlyle is said to have rescinded its offer after the email fiasco. So, now Kwan is sadly left with nothing. Maybe this is a good moment to double down and do an MBA?

Separately, the Financial Times has a profile of John Cryan which seems to confirm suspicions that he will preside over some serious pay cuts at Deutsche Bank. Cryan is a "shy man" reportedly disapproved of UBS's lavish 150th birthday celebrations at London's Somerset House on the grounds that they were a, "waste of money." He has an "enormous brain" and a "freakish work ethic" and when he worked at SG Warburg in the 1990s Cryan always ate in the, "cheap English canteen," and, "he took the oldest black leather satchel into meetings and travelled economy class.”
