Rates for panamaxes, the largest coal and iron-ore carriers to pass through the Panama Canal, may jump about 55 percent as Japan buys more raw materials to generate power and rebuild after its worst-ever earthquake.

Japan may need to buy an extra 6 million metric tons of coal after the disaster crippled nuclear plants, Credit Suisse Group AG estimates. That’s enough to fill about 90 panamaxes.
