WASHINGTON (Reuters) - The United States is determined to push Iranian oil exports to zero, U.S. Special Representative Brian Hook said on Wednesday, through a ‘calibrated’ approach using maximum economic pressure without lifting oil prices.

The United States resumed sanctions on Iran’s oil, shipping and banking industries on Monday after President Donald Trump pulled out of a 2015 nuclear deal earlier this year. It granted temporary exemptions to eight countries allowing them to continue importing Iranian oil, although it said the ultimate goal is to completely halt exports from Iran.

Hook declined to give details of the confidential bilateral deals with the countries, which include China, India, South Korea, Taiwan, Japan, Greece, Italy and Turkey.

The deputy head of Iran’s elite Revolutionary Guards, Brigadier General Hossein Salami, said on Wednesday that his country can flourish under sanctions and would defeat the United States in the economic war.

“We have been very careful about applying maximum economic pressure (on Iran) without lifting the price of oil and we have done that successfully,” Hook told reporters.

“We are going to be continuing our path to zero,” Hook said. “We do want to achieve maximum pressure without harming friends or allies and we don’t want to lift the price of oil. ... We have calibrated this very well.”

Iran’s exports peaked at 2.8 million barrels per day (bpd) in April, including 300,000 bpd of condensate, a lighter form of oil. Overall exports have since fallen to 1.8 million bpd, according to energy consultancy Wood Mackenzie, which estimates volumes dropping to 1 million bpd.

Oil prices in October rallied above $85 per barrel on fears of a steep decline in Iranian exports and have fallen since then. On Wednesday, oil slipped after U.S. crude output hit another record and domestic inventories rose more than expected. [O/R]

Asked if the administration had a target in reducing Iranian oil exports in the next six months, Hook said, “I can’t tell you what our target is; we do have a target.” He added that the ultimate aim was to halt Iranian exports entirely.

He said the United States expected increased global oil supply in 2019, surpassing demand, which would better position Washington to ask Iranian oil importers to reduce purchases to zero.

Washington’s “maximum pressure” strategy would also apply to the escrow accounts holding Iranian oil revenues, Hook said, adding that the Treasury Department would ensure that the accounts are never used for illicit goods. “We will police these very aggressively,” he added.

‘FLOATING LIABILITY’

Hook raised the possibility that countries and port operators could face U.S. penalties for facilitating Iran’s “illicit activities” if they allowed Iranian ships access to international waterways and port facilities. Iran regularly shipped “millions of barrels of crude” to Syria in support of Syrian President Bashar al-Assad, he said.

Hook said Iranian vessels would lose access to international insurance markets under U.S. sanctions.

“From the Suez Canal to the Strait of Malacca and all choke-points in between, Iranian tankers are a floating liability,” Hook said. “Self-insured Iranian tankers are a risk to the ports that permit them to dock, the canals that allow them to transit and the boat that cross their path. This exposes the entire maritime shipping network to immense liability.”
