With the northern hemisphere winter approaching, the oil-price slump will cushion households and businesses during a period of slowing economic growth. Countries that import oil and have current-account deficits, such as South Africa, also will stand to benefit. China is the world's biggest importer of oil and is already battling a broader moderation in its economy amid a trade war with the U.S. and domestic challenges.
What does it mean for inflation?
Lower oil prices mean less pressure on inflation and less pressure on central banks to raise interest rates. One example: Bloomberg Economics says the energy slump is a game changer for India and could mean the Reserve Bank of India shifts to a neutral outlook.
What about emerging markets?
Every $10-per-barrel fall in oil prices boosts incomes by about 0.5 to 0.7% of gross domestic product in major emerging market oil importers, Capital Economics analysts estimate. The same discount will cause a 3% to 5% loss of GDP in most of the Gulf economies, and a slowdown of 1.5% to 2% of GDP in the United Arab Emirates, Russia and Nigeria, all on an annualized basis, according to the analysts.
What does it mean for the United States?
Trump has described the slump in oil prices as the equivalent of a tax cut. Still, diminishing American reliance on imported oil due to the emergence of shale production will erode the positive economic consequences at the industry level.
