The global bond selloff has crossed an important line. The benchmark US 10-year Treasury yield rose above 5.27% on Monday, its highest level in nineteen years, while two-year yields were heading for their largest monthly increase since early 2023.The move is broader than one weak auction or one central-bank decision. Oil above $100, resilient activity and renewed policy tightening are forcing investors to reconsider the assumption that inflation would fade quickly enough to return borrowing costs to the post-financial-crisis norm.
Policy and term risk are moving together
The Federal Reserve raised its target range to 3.75% to 4% on 16 September, citing solid activity, robust capital investment and inflation that remained elevated. Markets have since pushed long yields much higher, adding compensation for duration, supply and the uncertainty around future inflation.That distinction matters. A central bank controls the overnight policy rate. A ten-year yield also reflects fiscal issuance, inflation credibility and the price investors demand to hold long-duration assets. Rising short and long rates together tighten almost every financing channel.
The hurdle rate has become the market's central variable
At 5%-plus sovereign yields, an equity story must offer more than revenue growth. Infrastructure projects need higher contracted returns, leveraged acquisitions become harder to justify, and governments pay more to refinance without adding a single service.Global Markets Review's assessment is that investors should stop treating the selloff as a temporary valuation shock. Until inflation expectations, energy risk or fiscal supply retreat, the default comparison for every risky asset is a government bond offering a historically substantial nominal return.The immediate pressure will be uneven. Cash-rich businesses gain interest income and refinancing flexibility. Highly valued companies, indebted states and households resetting fixed-rate loans absorb the cost.
The next signal is whether credit follows sovereign debt
Watch investment-grade spreads, mortgage resets, auction demand and the share of corporate issuance used for refinancing rather than expansion. Stable credit spreads would show that investors still distinguish higher base rates from default risk.If sovereign yields remain high and credit spreads widen at the same time, the market will have moved from repricing money to rationing it.
