Currency Gains Drove Most of Berkshire's Q2 Operating Earnings Increase

Berkshire Hathaway's operating earnings increased by about $1.8 billion in the most recent quarter, a jump of roughly 16%. Coverage of the results notes that approximately $1.2 billion of that increase came from foreign-currency effects tied to the conglomerate's non-dollar denominated debt, rather than from improved results at its insurance, railroad, energy or manufacturing units. The distinction matters for investors tracking the durability of Berkshire's earnings power, because currency translation gains reverse when exchange rates move the other way and are not a recurring source of profit. Excluding the currency line, the underlying increase in operating earnings was materially smaller than the headline figure suggests.
