Global Bond Yield Volatility

Analysis

The turmoil across global debt markets began mid-week with volatile trading in US government bonds, tracking sharp movements in crude oil prices. Following an early morning period of relative stability, US Treasury yields moved higher. The sell-off originating in the United States spread quickly across international financial hubs, fueling a sharp rise in yields worldwide. The most prominent impact was registered in Japan, where 10-year government bond yields surged to their highest level since 1996, marking a nearly three-decade high.

The sharp rise in market rates immediately weighed on equities and borrowing costs. Nasdaq futures dropped between 1% and 1.2%, deepening a sell-off in semiconductor stocks. Meanwhile, the pressure in debt markets was felt across the real economy in the United States, where mortgage interest rates reached 7%. In Europe, by contrast, bond markets later began to calm, with government debt yields easing slightly after the initial wave of heavy selling.

Toward the end of the week, the global rout in debt markets showed signs of slowing, and leading Wall Street indices shifted into positive territory. The shift in investor sentiment was supported by stronger-than-expected US economic data, new corporate deals, and the conclusion of a summit in Washington between US President Donald Trump and Chinese leader Xi Jinping. At the same time, investors closely tracked geopolitical developments, particularly relations between the United States and Iran and wider events in the Middle East. Despite the relative stabilization, the precise trajectory of US yields remained a subject of conflicting reports at week's end.
