Federal Reserve Chairman Kevin Warsh used his first Jackson Hole address as Fed Chair to make an inflation-forward case, arguing that responsibility for 65 months of elevated inflation sits with the central bank. According to Deutsche Bank analysis, Warsh pointed to PCE inflation running at 3.7% over twelve months and 4.1% over six, stating 'we have work to do.' The immediate market response was predictable, with 2-year Treasury yields rising 11 basis points and the implied probability of a September hike moving from 35% to 58%. However, something else Warsh said received far less attention: 'Trends matter most.' As Deutsche Bank argues, this phrase may also apply to the Fed's decision-making around sovereign debt across the short, medium and long term.
Federal Reserve Chairman Kevin Warsh told G20 finance leaders that the world is experiencing a global investment surge that is helping to power growth, reversing past savings glut that kept capital idle due to a shortage of investment opportunities. According to reports from Reuters, Warsh made these remarks during his first international economic policy meeting since taking office in May, speaking at the G20 opening plenary session on August 31 in Asheville, North Carolina. As reported by Reuters, Warsh emphasized that the situation has reversed significantly from previous G20 meetings, even before the 2008 global financial crisis, when participants would have been discussing 'a global savings glut.' 'If I were to try to characterize this moment, it would be one of a global investment surge,' Warsh stated, adding that the notion of secular stagnation no longer applied to the current economic environment. The remarks were made alongside U.S. Treasury Secretary Scott Bessent during the plenary session with finance ministers and central bank governors from G20 countries.
One of the biggest changes affecting global capital flows is the enormous investment being directed toward artificial intelligence infrastructure. As reported by Reuters, companies and investors are financing large bond offerings to build data centers, power infrastructure and other facilities required to support the rapid expansion of AI. These investments are creating new destinations for capital that previously might have flowed into safer assets such as U.S. government bonds. This shift has implications for both the Federal Reserve and the U.S. Treasury, as for decades, strong global demand for Treasuries helped keep government borrowing costs relatively low. The abundance of savings also contributed to favorable financing conditions for households, including lower mortgage rates. The emergence of competing investment opportunities could reduce that demand for Treasuries and contribute to higher government bond yields. Deutsche Bank notes that AI is the only credible route to easing the debt burden, but its capital demands could worsen the Treasury funding contest before productivity arrives.
According to Deutsche Bank's dbDataInsights survey, people in the US and UK see more opportunity in equities than in bonds, with 28% of US respondents and 25% of UK respondents preferring stocks over bonds during uncertain periods. This represents a reversal of the traditional relationship where bonds provided counterweight during market weakness. Deutsche Bank reports that bonds have at times suffered significant losses alongside equities since 2022, with the traditional group of haven assets - gold, dollar, Swiss franc, yen, 10-year Treasuries and Bunds - failing more often than working since 2020. The bank calculates that the number of VIX spike events per month has risen 51% from its pre-Covid level since interest rates normalized in 2022. This trend is particularly concerning given that sovereign debt is the greatest concern among Deutsche Bank's six global forces framework, with the bank's sovereign deficits indicator deteriorating for three decades.
The changing global savings pattern comes at a time when sovereign debt concerns are reaching critical levels. According to Deutsche Bank, the Congressional Budget Office expects public debt to rise from around 100% of GDP to 120% by 2036, with deficits exceeding 6% of GDP. Even in Deutsche Bank's optimistic scenario where AI adoption accelerates, productivity rises materially and government spending contributes positively to growth, the sovereign debt indicator only returns from clearly negative territory to broadly neutral by 2030. Deutsche Bank believes AI could prove more consequential than the internet boom of the 1990s, with its technology indicator potentially exceeding its 1990s peak by 2030, implying a potentially powerful productivity boost. However, the capital intensity question matters most for sovereign debt, as a capital-hungry AI buildout could compete with government borrowing for savings just as fiscal financing needs rise. The challenge will be determining whether the emerging investment boom represents a durable increase in the economy's productive capacity or a source of additional inflationary pressure.
