J.P. Morgan CEO Jamie Dimon states that it costs the corporation $1 Billion a year to protect assets worth $350 Billion against risk of exposure to interest rate movements. However, if the interest rates were to move higher, J.P. Morgan would make even more money. Sounds like a very prudent hedging strategy.
And their risk overseas is so nicely spread that any one country going wrong would not hurt J.P.Morgan's books to any effect.
CEO Jamie Dimon presides over a corporation with a winning and very sound strategy. No wonder its stock is rising after his testimony.
