Commodity Watch shows that the price of copper closed on Sept. 3 at the unofficial London Metal Exchange price of $3.48/lb. Also noteworthy: aluminum and zinc, both of which are up around 5% in five days.

With the yen up almost 10% vs. the dollar since the end of March, some numbers in Commodity Watch (like copper at $3.34/lb.) are mighty interesting to stare at. There’s also a nice chart of tin spot prices; you shoulda bought it a year ago!

Aluminum’s spot-market price slipped 8% in one week, according to Commodity Watch. Crude oil finished last week closer to $60/barrel than $90. And the U.S. dollar seems to have bottomed, maybe.

Is the summer “driving season” over now? The price of crude oil fell by $5 last week, according to Commodity Watch. Copper? It’s right there, near $3.25/lb.

With the dollar down below where it was at the end of April, our Commodity Watch figures for the past week are full of “up” numbers. Copper, for example, rose 1.2% last week to $3.33; tin hurdled the $9/pound mark; and gasoline rose $.04.

As the U.S. dollar index hasn’t been below 82 in a while now, the bounces up in copper, crude oil, silver, and aluminum (up almost 6% last week) that you’ll find in Commodity Watch probably might not be a surprise.

Last week’s hottest commodity was tin—which was up 7.4%. But right behind it was copper, bouncing off the $2.95 level on up to $3.17, for a gain of nearly 6.5%. That’s what you’ll find, along with a lot more data and a few charts, in Commodity Watch.

Copper bounced down to the wrong side of $3/lb. last week and is down 11% since April 30. As you’ll see in Commodity Watch, almost every other item we track (except the euro and the yen) took it on the chin last week and looks pretty bad compared with the end-of-April close. Deflation, anyone?

Copper bounced back up above the $3/lb. level in trading last week, and several other items we follow in Commodity Watch did, too. But the U.S. dollar weakened just a bit, and crude oil regained what it lost in the earlier week. What does all this mean? A slow week in early July might mean just about…nothing.

In Commodity Watch, copper ended last week at $2.90/lb., all of the other metals took gas, while the U.S. dollar index fell (and gold did as well). What’s the story?

Copper’s price, anchored around $3 lately, is still down 15% and more since April started. Crude oil is down 9.5% in the same time. And the U.S. dollar, you’ll learn in Commodity Watch, is up 5.6% in less than three months. Makes sense to you?

Four of five base metals we track weekly went up last week. Gold set a new record, silver hurdled the $19/oz. barrier, and the U.S. dollar took some gas. But the price of copper remained (third weekly close in a row) below $3 per pound. What does it all mean? We’re not sure, but you can keep an eye out with Commodity Watch.

Copper remains below $3/lb.—and is more than $.64 down from its April 2 close; Zinc’s per-pound spot price is down $.30. For other weird (and current) numbers, see Commodity Watch.

In a week in which key items in Commodity Watch fell like a stone (all five of the metals), copper fell—decisively???—below the $3/lb. mark. Compared with the close of April 2, everything we watch is down, except for gold, natural gas…and the U.S. dollar!

Copper is almost 3% lower than it was three months ago, but it’s still close to $3.15/pound. After bouncing below the $70/barrel mark, the spot price of crude oil is back up near $75. What’s going on? You tell us—but first see Commodity Watch.
