5% Treasury Yield Loses Shock Value as Investors Eye 6% Threshold

Global investors are recalibrating the upper bound of tolerable US borrowing costs after the 10-year Treasury yield breached 5% this month, a level once viewed as a tripwire for financial markets. Attention is shifting toward 6% as a potential new threshold for capital allocation decisions. JP Morgan analysts said the equity market's "breaking threshold" may now sit in the 5.5%-6.0% range, citing a structural shift in the global economy where AI, healthcare and services firms are less sensitive to borrowing costs. A 6% yield would imply higher inflation expectations, US fiscal sustainability concerns, or a prolonged high-rate environment. Invesco's Paul Jackson said world stocks historically decline when the 10-year yield averages 4.72% over 12 months and then rises, though the current average is 4.34%. Emerging markets saw their largest bond fund outflows in months last week.
