Overview
- On Thursday, October 1, long‑term U.S. Treasury yields spiked to roughly the mid‑5% range, validating warnings that bond costs could climb substantially and increasing benchmark borrowing rates for governments, mortgages and corporate loans.
- Oil prices rose sharply after reports of attacks on Saudi infrastructure, a possible additional U.S. carrier deployment and Chinese refiners curbing exports, a move that added near‑term inflation and supply‑risk concerns for markets.
- Investors reacted with mixed U.S. equity moves and elevated caution ahead of Friday’s U.S. September jobs report, which markets see as key for the Federal Reserve’s interest‑rate outlook.
- Emerging markets felt clear pressure: the Mexican peso slid to its weakest level since December 2025 and Argentina’s central bank resumed net dollar purchases (about USD 93m), lifting reserves back above USD 48.2bn even as sovereign risk jumped toward ~635 basis points.
- Higher long‑term yields raise the cost of refinancing and could squeeze borrowers and fiscal budgets, so markets will watch U.S. payrolls, oil‑supply developments and Argentina’s reserve flows for signs of further stress or stabilization.
