The U.S. Army Just Called China’s Bluff in the Rare Earth War

Just recently, in a span of about six weeks, one impressive company was selected by the U.S. Army to build and operate rare earth processing facilities on an American military base…the first time the Army has ever done this. That same company closed $100 million in institutional financing, giving it a war chest of roughly $130 million. It was also formally added to the Russell 3000 Index. And it locked in MOU’s for feedstock agreements covering billions of tonnes of rare earth-bearing material from sources across Wyoming, Appalachia…

Oil Prices Ignore the Warning Signs in Physical Markets

Oil price movements since the start of March this year have become the topic of dozens of discussions.

It appears the reason is sheer optimism and a bet on market adaptability. However, there is a problem with that. Adaptability has limits.

To prevent localized grid blackouts or harmful voltage spikes, utilities are increasingly pairing renewables with battery storage and/or rapid-response natural gas plants to smooth out fluctuating supply. However, Finland has now come up with a rather eccentric method to store excess renewable energy and release it…

Refined Fuels, Not Crude, Are Driving the Oil Market Crunch

Oil prices have just come off a fresh two-month high as the crude oil market has tumbled this week amid signals of de-escalation in the U.S.-Iran conflict. Despite the slump in crude prices and the extreme volatility in the past five months, the refined product market continues to tighten with refining margins at record highs because the supply of petroleum products is much tighter than crude supply. Refining margins held at record highs even as crude oil prices soared last week to $100 per barrel. That’s because global gasoline, diesel,…
