What a difference a year makes: Just more than 1 year ago Royal Bank of Scotland (RBS) paid $100bn for ABN Amro (80% in cash). For this amount, RBS could today buy: Citibank $22.5bn, Morgan Stanley $10.5bn , Goldman Sachs $21.0bn, Merrill Lynch $12.3bn, Deutsche Bank $13.0bn and Barclays $12.7bn, And still have $8bn change for booze, drugs and hookers. Not bad at all.
