NEW YORK (Reuters) - Oil prices edged higher on Tuesday, helped by weakness in the dollar, although gains were capped as concerns mounted over a U.S. slowdown and the impact of tariffs on global economic growth.
Brent crude futures were 36 cents, or 0.5%, higher at $69.64 a barrel by 1:01 p.m. EDT (1701 GMT) after falling as low as $68.63 in early trade. U.S. West Texas Intermediate crude futures gained 28 cents, or 0.4%, to $66.31 a barrel after previous declines as well.
Both benchmarks closed 1.5% lower in the previous session.

Oil prices, however, pared back some gains after U.S. President Donald Trump said on Tuesday he had instructed his commerce secretary to add an additional 25% tariff on all steel and aluminum imports from Canada, bringing the total tariff on those products to 50%.
"That kind of drama is adding to the volatility here," said Phil Flynn, senior analyst with the Price Futures Group.
Trump's protectionist policies have shaken global markets, imposing and delaying tariffs on major oil suppliers Canada and Mexico, while also raising duties on China, prompting retaliatory measures.
Over the weekend, Trump said a "period of transition" was likely and declined to rule out a U.S. recession.
Stocks, which crude prices often follow, extended their decline after slumping on Monday when the S&P 500 posted its biggest one-day drop since December 18 and the Nasdaq slid 4.0%, its biggest single-day percentage drop since September 2022.
In supply, U.S. crude oil production is poised to set a larger record this year than prior estimates, at an average 13.61 million bpd, the U.S. Energy Information Administration said on Tuesday.
Investors are waiting for U.S. inflation data due on Wednesday for clues on the path of interest rates.
Meanwhile, they are closely monitoring OPEC+ plans after the producer group announced plans to increase output in April.
A scaling back of U.S. tariffs would ease fears of inflation and economic contraction, said PVM analyst Tamas Varga, but the recent oil price plunge meant it was "hard to see OPEC+ going ahead with its plan and releasing oil back to the market from April."
On Friday, Russia's Deputy Prime Minister Alexander Novak told reporters that the OPEC+ producer group would go ahead with its April increase but may then consider other steps, including reducing production.
Brent is finding strong technical support at around $70 a barrel and may look to stage a bounce, said Suvro Sarkar, energy sector team lead at DBS Bank, adding that the OPEC+ supply response would be flexible, depending on market conditions.
