"The Strategic Petroleum Reserve is in place for emergency natural disasters. So I would not recommend [tapping it], and I don't think the president would either," Perry was quoted by Platts energy news services as telling reporters at the World Gas Conference in Washington.
"We look at this as an opportunity for OPEC members to fill this gap, if you will," he added.
S&P Global Platts Analytics expects a loss of more than one million barrels a day by November if the US manages to force buyers of Iranian crude to wind down their imports.
Perry believes, however, that since Saudi Arabia will be able to produce 11 million barrels of oil a day and that Russia will increase output "the worldwide crude market does have some stability."
According to Bank of America Merrill Lynch experts, disruption to oil supplies from Iran as a result of US sanctions could see crude prices soar to around $90 a barrel.
Oil prices spiked this week after Washington said it would offer no extensions or waivers to Iran's oil buyers when sanctions return in November.
The re-imposition of sanctions on Iran, which US President Donald Trump threatened in May, includes a universal ban on Iran buying or acquiring US dollars as well as restrictions over purchases of crude oil from the country and investing in its oil projects.
Iran’s Oil Minister Bijan Namdar Zaganeh said on Friday that the US could not have imposed sanctions on the country’s oil sector if Iranian crude exports had reached 4 million barrels a day.
