Reuters survey: The Federal Reserve's interest rate hike expectations for December remain solid, but there is still controversy over the end of the tightening cycle

A Reuters survey shows that about 55% of the economists surveyed, or 56 out of 101, expect that the interest rate hike in December will mark the end of the current tightening cycle, a figure that is basically unchanged from last month.However, 45 economists still expect that the Federal Reserve will raise interest rates at least two more times, including more than half of the surveyed primary dealers, which is consistent with the expectations reflected in market pricing, and believe that the risks to the inflation outlook have not changed since the U.S. midterm elections. Changes in the political landscape are unlikely to quickly alleviate inflationary pressures.Despite market hopes that the nearly 9-month-long Middle East conflict could be resolved, leading to a drop of over 22% in crude oil futures prices from the late October peak, inflationary pressures still persist. A strong labor market, resilient economic growth, and inflation remaining above the Federal Reserve's 2% target for nearly six years all indicate that further tightening of monetary policy is still necessary.Wells Fargo Chief Economist Tom Porcelli stated, "The Federal Reserve's decision-making depends on the upcoming inflation data, which will prompt it to raise rates again. In fact, the Federal Reserve has every reason to raise rates at the October meeting."

According to a report by Decrypt, due to the long delivery cycle of new gas turbines, AI data center developers are turning to second-hand gas turbines and retired jet engines. Data from the energy consulting firm Wood Mackenzie shows that the average delivery time for new gas turbines in the United States has reached 6 years, with related delivery discussions focusing on 2030 and 2031. Reuters reports that global gas turbine orders have exceeded 100 gigawatts, while manufacturers' annual production capacity is estimated to be only 60 to 70 gigawatts. Siemens Energy, GE Vernova, and Mitsubishi Heavy Industries have all stated that order growth exceeds production capacity.One response is to retrofit gas turbines based on aircraft jet engine technology. AI infrastructure company Crusoe ordered 13 units from ProEnergy in Missouri in April, each with a rated power of 50 megawatts, totaling 650 megawatts, for future data centers in the United States. Equipment brokers and energy analysts say that well-maintained second-hand turbines sell for about $1.5 million to $1.7 million per megawatt, while new ones cost about $2 million to $2.5 million per megawatt.The International Energy Agency expects global data center electricity consumption to increase from 485 terawatt-hours in 2025 to 950 terawatt-hours in 2030, with electricity consumption for AI facilities expected to double during the same period. The U.S. Environmental Protection Agency states that stationary turbines and engines used by data centers must comply with federal air pollution standards. Finnish manufacturer Wärtsilä told Reuters that it has received orders for about 3 gigawatts of gas engine generators from U.S. data centers since spring 2025.

The Zama spin-off project Raycash has launched on the Ethereum mainnet and entered the private testing phase

According to The Block, the stablecoin payment startup Raycash, spun off from the privacy protocol Zama, has launched on the Ethereum mainnet and is currently in the private testing phase. Raycash stated that over 75,000 people had joined the waiting list before the launch, and access will be opened in batches during the private testing period, followed by a full launch.Raycash is built on the Zama protocol and employs fully homomorphic encryption technology to encrypt on-chain balances and transaction amounts. Users can wrap stablecoins 1:1 into tokens under the ERC-7984 confidential token standard for payments and receipts, and earn yields through Morpho, with amounts and balances kept private; the underlying stablecoins can be retrieved through permissionless unwrapping. Initially, the application supports USDC and allows for bank transfers, credit card or stablecoin deposits, and withdrawals to bank accounts, with Ethereum Gas fees handled by the platform in the background, so users do not need to hold ETH.Raycash stated that its wallet is a self-custodial wallet, and confidential tokens do not have freezing or confiscation capabilities at the token level, allowing users to grant viewing permissions to specific parties such as accounting and auditing institutions. Additionally, the Raycard for privacy consumption is under development.
