By Thomas Biesheuvel, Prejula Prem and Annie Lee (Bloomberg) — The super-charged rally in commodity prices has made shipping more expensive than any time in the past decade, reviving the fortunes of an industry that was on its knees just a year ago.

The surge also highlights the pressures the commodities industry is under to meet that growth.
