Warsh Sees Global Investment Surge Replacing the Savings-Glut Era

Asheville, North Carolina, United States, 1 September 2026 – Federal Reserve chair Kevin Warsh has argued that the global economy is moving from an era of excess savings into an investment surge, a shift that could reshape growth expectations, bond supply and the neutral level of interest rates. Speaking during a Group of Twenty finance gathering, Warsh said the secular-stagnation framework no longer describes present conditions. He suggested underlying US growth and productivity could outperform the traditional estimate of about 1.8%, supported by heavy spending on artificial intelligence, data centres, power networks and other infrastructure.

The same investment cycle is creating large financing needs. Corporate bond issuance for digital and energy infrastructure is competing with government borrowing, while US federal debt has moved above US$40 trillion. That combination can support productivity over time but also keep long-dated yields elevated as markets absorb more duration. The immediate market response should be interpreted in the context of monetary policy and global capital allocation. Headline figures provide direction, but the durability of the change will depend on implementation, counterparties and the broader cost of capital.
