Global Bonds Suffer $2.5 Trillion Wipeout Amid Iran War Fears
The specter of stagflation, fueled by the escalating conflict in Iran, has erased more than US$2.5 trillion from the value of global bonds in March alone. This staggering loss is on track to become the most severe monthly decline in over three years, sending shockwaves through financial markets worldwide.
Bond Market Plunge Mirrors 2022 Crisis
According to data from a Bloomberg index, the total market value of government, corporate, and securitized debt has plummeted to US$74.4 trillion, down from nearly US$77 trillion at the end of February. This represents a 3.1 percent drop for the month, marking the most significant contraction since September 2022. During that period, the United States Federal Reserve was aggressively hiking interest rates to combat inflation.
Stagflationary Pressures Intensify
The bond selloff has been driven by a surge in oil prices, which has accelerated inflationary pressures and eroded the value of fixed-income payments from debt. "Markets are beginning to price what I think is going to be a stagflationary impulse manifested very soon," said Kathryn Rooney Vera, chief market strategist at StoneX Group Inc., in an interview with Bloomberg Television. "The longer this goes on, the higher oil prices can rise."
While the decline in bond values is less than the roughly US$11.5 trillion lost in global equities, it is particularly unexpected. Debt instruments typically gain during times of geopolitical turmoil as investors seek safe-haven assets. However, the current crisis has upended this conventional wisdom.
Government and Corporate Debt Lead Declines
The selloff has been broad-based, with government debt leading the declines. A Bloomberg index of sovereign securities has slid 3.3 percent in March, while corporate bonds have fallen 3.1 percent. The downturn gathered momentum on Monday after U.S. President Donald Trump threatened to attack Iranian power plants unless the country reopens the Strait of Hormuz. Iran responded by warning it would close the waterway "completely" if such an attack occurred.
Central Banks Face Mounting Pressure
As bond yields climb to multi-month highs, central banks are under increasing pressure to address inflationary risks. The Fed is expected to consider rate hikes at its April policy meeting if energy prices remain elevated and the jobless rate stays stable, according to interest-rate strategists at BNP Paribas. Similarly, European Central Bank Governing Council member Joachim Nagel indicated that the ECB may need to raise rates as early as next month if price pressures intensify due to the Iran war.
"Higher inflationary pressures limit central banks’ ability to help and some will be forced to hike into a down growth cycle to arrest inflation and also FX depreciation," explained Trinh Nguyen, a senior economist at Natixis in Hong Kong.
Global Yield Surge Reflects Market Anxiety
The bond market turmoil has triggered a surge in yields across multiple regions:
- U.S. Treasury yields have reached their highest levels in months after three consecutive weeks of losses.
- In Asia, government bond yields in India, Japan, and South Korea have all climbed.
- Australia’s 10-year yields rose to their highest level since 2011.
- New Zealand’s yields are at their highest since May 2024.
This widespread yield increase underscores the global scale of the financial anxiety stemming from the Iran conflict and its stagflationary implications. As the situation evolves, investors and policymakers alike are bracing for further volatility in the bond markets.
