Cardano holders are being asked to bet $5 million on copper hitting a new record

Cardano's community treasury is being asked to commit 22 million ADA, worth about $5 million, to a proposed copper reserve that would require the metal to rise nearly 50% to break even under the proposal's assumptions. Toto Finance's plan would allocate roughly two-thirds of the budget to physical copper, with the remainder covering operations, while consuming just over half of Cardano's remaining withdrawal allowance; voting closes Nov. 15. The proposal could expand Cardano's tokenized real-world asset ambitions, but its substantial break-even hurdle and non-replenishing treasury cap could intensify debate over the use of community funds.

Palm Oil Set for 3rd Straight Weekly Gain

Malaysian palm oil futures are heading for a third consecutive weekly gain, rising nearly 1% for the week and holding above MYR 4,800 per tonne amid tightening supply expectations and strong export demand. Shipments surged 58.5%–78.4% during Oct. 1–20 versus the same period in September, while severe El Niño conditions, Indonesia's upcoming B50 biodiesel mandate, and festival-related buying from India supported prices. Continued supply constraints and stronger biodiesel demand could extend palm oil's rally, although inflation-driven weakness in food demand may limit further gains.

Wake up! The long bond's up two points!

US Treasuries surged as investors fled risk amid growing concerns over the AI investment boom, with 10-year Treasury yields plunging 19 basis points in their biggest daily drop since early 2023. Fed funds futures rallied as much as 22 ticks, Meta shares fell almost 7%, and CoreWeave dropped another 10% as concerns over AI infrastructure funding weighed on markets, while Brent crude remained above $113 a barrel.
