Transits have gone from an average of over 60 a day to less than 6 a day. None of the transits are significant amounts of oil. That is called "effectively closed."

400 million barrels from multiple countries oil reserves, with 172 million coming from the US oil reserves for now. Other countries have oil reserves closer to the immediate need for oil, so they were cajoled into release oil on the promise that in the near future it would be replaced out of our oil reserves. That is not included in the 172 million, so we may be losing quite a bit more than 172 million.
