But the big question was whether Friday's bounce was due to Ike coming ashore and apparently not leaving too much damage to the oil and gas producing, refining and distribution facilities along the Texas coast between Houston and Galveston.
At least 13 refineries in Texas were shut for the passage of Ike.
That was 3.64 million barrels a day of refining capacity.
But as we have seen after storms in the past month, once the situation is clarified, then the prices of oil, petrol and gas will ease quite quickly.
And that's what seems to have happened after Ike as oil fell in early electronic trading in new York to $US99.25 after dropping to $US98.75 a barrel early this morning, our time.
The October New York contract briefly dipped to $US99.99 on Friday, falling under the $US100 level for the first time since April 1.
But Nymex crude in New York rose 31c to close at $US101.18 a barrel.
In London, October Brent North Sea crude eased 6c to settle at $US97.58 a barrel.
Oil prices are down $US47.29 a barrel since the peak of $US147.47 on July 11.
For all the sound and fury of Ike, the real story remains the continuing dip in American consumption of oil-based energy products.
US energy consumption is down 3.8% over the past four weeks compared with the same period in 2007, while petrol consumption is down 2.1%.
On the Chicago grain markets, the emphasis is shifting as the harvest gets underway and the yields of wheat, corn, soybean and other crops becomes clearer.
The United States Department of Agriculture said on Friday that the hugely important corn harvest won't be as big as thought because of widespread dry, warm weather last month.
The USDA said farmers will harvest 1.8% less corn than forecast last month, while the soybean harvest will be down 1.3%, but wheat output will be higher in both the US and globally.
The USDA forecasts steeper increases in corn and soybean prices, which have eased from the record levels set earlier in the year.
December corn rose 30 USc, or 5.6% on Friday to $US5.6325 a bushel in Chicago. That pushed prices up 2.7% this week. That left the price of the most active contract down 30% from the all time high of $US7.9925 in late June.
November soybean futures rose 26c, or 2.2%, to $US12.02 a bushel in Chicago. The price rose 2.1% last week. Beans are down 27% from the all time high of $US16.3675 hit in early July.
The USDA said the average cash corn prices in the crop year that began September1 were $US5.50 a bushel, compared with $US5.40 estimated in August and $US4.20 in the most recent year.
The Department said cash soybean prices will average $US12.35 a bushel this crop year (which started on September 1), up from last month's estimate of $US2.25 and up from $US10.15 in the previous year.
Wheat was the odd one out with prices falling for a third straight week after the USDA made no change in its estimate of US domestic stocks in the coming year, suggesting that there might be more grain than the market thought.
The USDA said it expects US carryover stocks on May 31 (the end of the wheat crop year) will be around 574 million bushels, while exports will total 1 billion bushels, matching the forecasts made in August by the USDA.
December wheat futures fell 7c to $US7.1925 a bushel on Friday, down 4.3% over the week and 19% this year.
The USDA also increased its estimate of global production to a record 676.3 million tonnes, up from last month's forecast of 670.8 million tonnes.
Canadian farmers will harvest 25.4 million tonnes, up slightly from the August forecast of 25 million tonnes; European Union output will be 147.2 million tonnes, up from 143.2 million tonnes in the August forecast and these will offset declines in Australia and Argentina: Australia will produce 22 million tonnes, down from the 25 million tonnes in the August forecast and Argentina growers may harvest 12.5 million tonnes, 1 million tonnes down on the August estimate.
According to the USDA's forecast, the US is expected to be the largest exporter of wheat, followed by Canada, Russia, Australia, Ukraine and Argentina.
Copper had its best week in three, rising sharply on Friday as the US dollar lost ground against the euro.
Comex December copper futures added 7.15 USc, or 2.3%, to $US3.194 a pound. The price was up 3.1% last week
The metal climbed from Wednesday-Friday, as signs of declining mine output increased concerns that supplies may be tight next year. Some analysts, especially at Citigroup, are forecasting demand to run ahead of production next year.
Copper was also supported Friday by a fall in Chinese stocks.
Stocks overseen by the Shanghai Futures Exchange dropped 29% to 13,554 tonnes, the lowest level since 2003.
On the London Metal Exchange, three month copper rose $US192, or 2.8%, to $US7,122 a tonne, or $US3.23 a pound.
Gold jumped Friday, ending a nine-day losing streak, thanks to the US dollar's fall against the euro.
The euro rose as much as 1.5% against greenback, but ended off 0.3% for the week.
The Australian dollar finished at $US82.36 in New York, up from $US80.48 in Sydney on Friday afternoon and $US81.64 in Sydney the week before.
It was a rare gain for the currency, the first for a month or more over the week and the strongest daily performance for weeks.
Gold fell 4.8% over the week, despite a $US19 dollar an ounce rise on the day.
Comex December gold rose $US19, or 2.5% to $US764.50 an ounce in New York. The metal had fallen 11% from the end of August to last Thursday
Silver also had a rare rise, finishing up 24c, or 2.3%, to $US10.795 an ounce for the December contract. The metal still dropped 12% last week and is down 28% this year.
Gold is down 26% from the record $US1,033.90 reached in March and is off 8.8% in 2008.
