Dangerous Brew Rattles Bond Markets
The bond market faces challenges with rising yields, driven by government borrowing and inflation. Despite common assumptions, long-term rates are likely to remain elevated, impacting both the US and global economies.
Bond Market Instability and Rising Yields
Bond markets exhibit significant volatility, with yields rising sharply in recent weeks. This unexpected increase challenges conventional wisdom, particularly given historical trends. Government borrowing remains a substantial driver of this instability, especially in the United States, where fiscal expansion has exceeded the Federal Reserve's 2% inflation target since 2022. The additional demand from heavy corporate borrowing, such as for AI infrastructure, further pushes long-term interest rates upward. The recent selloff, characterized by declining bond prices and rising yields, saw the 30-year Treasury yield reach a 19-year high of 5.18% before a slight retreat, while the 10-year Treasury yield stood at 4.584%.
Yields have now surpassed 5% across various maturities, exceeding the Fed's short-term interest rate target of 5.25% to 5.5%. The Fed's target rate is 1.75 percentage points lower than the current short-term rate, indicating a substantial gap. The primary force behind the recent surge in yields has been investor demand for higher compensation over extended periods, signaling a shift in market expectations. This reflects a broader sentiment that debt, inflation, and populism collectively impact the bond market, preventing a return to lower rates.
Fiscal Deficits and Inflationary Pressures
Economic shocks since 2020 have been largely inflationary, starting with supply chain disruptions, the Russian invasion of Ukraine, and the energy crisis. Central banks have consistently fought to keep inflation below 2%, employing strategies such as near-zero short-term rates and bond purchases. Investors, perceiving bonds as a safe haven during crises, accepted low returns. However, with inflation persisting, central banks are now reconsidering these approaches.
Historically, the left and right political factions struggled to address fiscal deficits effectively. UK Prime Minister Keir Starmer faces resistance to spending cuts from his Labour Party. Similarly, in the US, President Biden's administration sought to pass a USD 2.1 trillion spending bill for the Pentagon, adding to an already high fiscal deficit. Fiscal imbalances contribute significantly to inflation, as increased government spending fuels demand. If the Fed continues to raise rates, it will exacerbate deficits, with estimates suggesting an additional USD 200 billion to deficits over a decade. This scenario puts pressure on central banks to raise rates further, amplifying concerns about inflation.
Global Economic Responses to Inflation
Global economic trends also contribute to inflationary pressures. U.S. deficits have averaged 6.2% of gross domestic product from 2010 to 2019, and 2.3% from 2002 to 2007, reflecting an underlying fiscal challenge. Japan, for instance, has leveraged its capital to absorb its massive debt, with a recent package aiming to alleviate energy costs by cutting gas taxes. Other nations, such as the US, are considering similar measures. This global fiscal expansion, coupled with supply chain fragilities, suggests a prolonged period of elevated inflation.
Geopolitical tensions, such as the war in Ukraine, further complicate the outlook. Japan's Prime Minister, Fumio Kishida, has acknowledged that the war will likely increase inflationary pressures. These “one-off” events, instead of being temporary, may have lasting effects on global prices. The public's expectations of higher inflation could become entrenched, leading to continuous price increases. This suggests that central banks worldwide will likely continue to raise rates to bring inflation back to target levels, creating an environment where investors demand higher yields.
Conclusion: Persistent High Yields Ahead
The prevailing view that deficits and inflation are distinct phenomena may be flawed; they often interact, with one feeding the other. The cost of living has eroded public trust in politicians, making them less willing to accept cuts to benefits or higher taxes. This creates a cycle where populist policies lead to higher deficits, which in turn fuel inflation. Kevin Warsh, former Fed Chair, has highlighted that AI productivity and cost cuts could offset some inflationary pressures, but this is a minority view. The consensus remains that persistent debt, tariffs, and oil prices will continue to drive inflation, leading to higher yields for the foreseeable future.
The implication is that confident expectations of higher earnings from equity markets might lead to a misjudgment of the true inflation trajectory. A combination of debt, populism, and inflation could further destabilize financial markets, making it imperative for investors to prepare for a sustained period of higher interest rates and increased market volatility.
