The cost of the RN65 brown .5 watt Dale MF resistors that are very popular with many amp makers and many DIYers jumped in price by about 40% just recently. I was unaware until I needed to replenish my stock on a few values - I thought it was an error.Nope, it's real - a nearly 40% increase. I didn't check any other Vishay products, so I don't know what else may have changed.
Watch out if you are planning/budgeting a project that uses them.
Follow Ups:
I go through hundreds of the RN65 series a month and the latest price increase does hurt. I recently had to order several hundred and the increase was very apparent with such quantity.Basically, anything with any amount of metal in it is going up.

Those are one of the better metal films and I use them in places to..Have you noticed the 1/2 resistor in the rn65 series is as big as many 2 and 3 watt resistors made now physically?
Amveco transformers, about35%Phoenix resistors, about 25%
Panasonic and Solen caps, about 15%
Evidently it's anything that uses nonferrous metal, especially copper, which is going through the roof. We may be using up the easily-available resources of the planet; mostly to put into SUVs and 72" plasma screens.
Everything with copper as a significant component is inflating rapidly. I don't think it has much to do with Euro health and environmental regulations.Just think. You make a resistor. Add up what you need. Then figure that your last shipment of copper was triple the price of a year ago. There's only so long you can hold out, wait for the commodity price to drop, before you have to raise your selling price. And if you have tried to wait it out (because you want to hold on to your customers) when you finally do give in, you have to relieve a lot of pressure on your own costs.
For quite some time there has been under investment in both mines and refining capacity for non ferrous metals, to the extent that there was no point in investing in this infrastructure as it would not make sufficient returns.With demand for commodities increasing from China in particular as that economy grows and the population becomes more affluent (they want to buy more stuff) as well as commodities that go into manufacture for export, the more demand than supply can, well, supply means prices go up. Simple really.
BTW, if you think that places like the mountains of South America, the jungles of Indonesia and PNG (where Mining has been going on for decades) are "easily accessible", it could be worth reconsidering that assessment.
Similarly, it really cracks me up when I read about complaints in the USA (I lived there for a significant period BTW) about "predatory oil companies". The notion that the "taps should be turned on" betrays a serious lack of understanding about how long it takes to find, evaluate and develop not only an oil or gas field, but pretty much any commodity.
I'll get off the soap box now. :-)
There is another reason, not simply to blame the fat and stupid Americans, it is the new and exploding China demand.

Last I checked they weren't. Maybe that's the cause of the cost increase.
They still aren't Mark - I had that same thought. I suppose we'll get another "bump" when they do.

Tin, possibly alloyed with a few % of Antimony, will coat Copper nicely. However, I suspect you are right about Zn coated Fe. ROHS gives the parts makers an opportunity to cheapen the product, while increasing the price. :~(
