Global Bond Market Rout Deepens as Japan’s Record Yields Heighten Inflation Concerns

Accelerating Global Bond Selloff
On 18 May 2026, benchmark U.S. Treasury yields surged—10-year at 4.631 % (its highest since Feb 2025), 2-year at 4.102 % (14-month peak), and 30-year at 5.159 % (one-year high). The rally coincided with a sharp decline in bond prices across the United States, Europe and Japan, marking the latest episode of a worldwide bond rout driven by mounting inflation expectations and geopolitical stress.
Inflation Pressures and Middle-East Conflict
Rising oil prices—Brent crude at $111 per barrel—followed a stalled effort to end the Iran-UAE war after a drone strike on an Emirati nuclear plant. Hotter-than-expected consumer-price and producer-price data from the United States, China, Germany and Japan reinforced fears that the conflict-induced energy shock could translate into broader price rises, prompting markets to price a >50 % chance of a Federal Reserve rate hike by December.
Japan’s Record-High Government Bond Yields
Japan’s bond market moved in tandem. The 30-year Japanese government bond (JGB) yielded 4.200 %—the highest on record (Reuters) and roughly 4 % in other reports. The 10-year JGB reached 2.800 % (its highest since Oct 1996) while other sources listed yields near 2.38 %–2.78 %. The surge follows the government’s plan to issue fresh debt for an extra budget aimed at cushioning the war’s economic impact, adding pressure to a debt-to-GDP ratio of about 230 %.

Impact on Global Liquidity and Capital Flows
Japan, the world’s largest net foreign creditor, traditionally supplied cheap yen-funded carry-trade capital to overseas markets. Higher domestic yields and an anticipated Bank of Japan (BoJ) rate hike in June make repatriation of Japanese institutional funds—particularly from the Government Pension Investment Fund (? $1.8 trillion)—more attractive. Analysts warn that such outflows could drain global liquidity, push U.S. and European yields higher, and tighten financing conditions for risk assets, including cryptocurrencies.

Criticism & Opposition
