Global bond yields are experiencing sustained upward pressure, even as oil prices decline from recent peaks. West Texas Intermediate crude was trading around $90 per barrel as of September 30, 2026. This trend is driven by lingering uncertainty surrounding the Middle East conflict and a resurgence of fiscal concerns. In Japan, the 10-year government bond yield eased to approximately 3.08% on September 30, retreating from 30-year highs. This retreat was supported by strong demand at recent government debt auctions, including for 2- and 40-year bonds, which saw better-than-expected investor interest. The demand for the 40-year bond sale was the strongest since 2020. These developments occur despite expectations that the Bank of Japan may continue to raise interest rates to combat persistent inflation, with a former BOJ official indicating a potential second consecutive rate hike in October. Falling oil prices, signaling reduced inflationary risks, also contributed to the easing of Japanese yields.
