Rising oil prices are helping the VanEck Vectors Oil Service ETF (OIH), which is up 30% year-to-date. The ETF ended last week’s trading session with a 10% gain thanks to fears of rising inflation. “Oil extended gains from its highest close in more than a year on a slump in U.S. oil inventories and a broader lift to the reflation trade taking place across global markets,” a World Oil article said. “Futures in New York rose near $63 a barrel. Inventories of U.S. oil have fallen by 40 million barrels over the last three weeks, with cold weather demand for heating fuels offsetting a rise in gasoline and crude stockpiles.”
