NEW YORK — Oil's plunge is spreading both pain and gain across the globe.
The price of a barrel has fallen by about half since June, punishing the economies of some major exporters. Russia's currency has nose-dived, for instance, and investors worry Venezuela could default on its debt.
For countries that consume a large amount of the world's oil, it's a different story. The world's four biggest economies — U.S., China, Japan and that of the European Union — all benefit from lower oil prices.
"Economically this is a good thing for the U.S., it's a good thing for Europe, it's a good thing for China and it's a good thing for most consumers," says Sarah Ladislaw, director of the energy and national security program at the Center for Strategic and International Studies.
Whether the price plunge ultimately helps or harms the global economy depends on how low oil prices fall, how long they stay low, and whether they trigger political upheaval that interrupts trade or spooks investors.
On Friday the global price of oil traded near $61, down 47 percent from its high for the year of $115. That drop removes nearly $5 billion a day in revenue from the global oil industry — and reduces costs for consumers.
The prices of bonds of some state oil companies and developing nations have fallen. And a possible recession in Russia next year could hinder European economies in their recovery. But the U.S. stock market is trading near an all-time high, helped by some of the best employment and wage growth since the Great Recession.
