Global government bond yields are surging, largely driven by escalating energy prices and renewed inflation fears. The Middle East conflict, specifically the Iran conflict, has pushed oil prices higher, with Brent crude futures rising to $95.61 per barrel and WTI crude back above $90 per barrel. This has reignited concerns about inflation, which was already a persistent worry.

Analysts predict that bond yields, particularly in the short term, are likely to continue their upward trend. The US 10-year Treasury note yield has already reached a near three-year high of 4.81% and is expected to climb toward 5%. Similarly, Japan's 10-year yield is above 3%, a 30-year high, and Australia's 10-year government bond yields have risen to 5.198%, their highest in over 15 years. The UK's 10-year gilt yield also reached 5.255%, its highest since 2008.

This bond sell-off is attributed to several factors: investors demanding higher premiums for inflation and fiscal risks, the large amount of debt entering the market, and geopolitical and macroeconomic anxieties. "Bond vigilantes" are seen as driving yields higher in protest of government deficits and rising interest costs. Charu Chanana, chief investment strategist at Saxo, suggests that a 5% yield on the US 10-year note might be necessary to attract buyers back into the market.

Adding to the pressure, Federal Reserve Chairman Kevin Warsh's hawkish comments last week about fighting inflation have led traders to increase their expectations for interest rate hikes. Money markets are now pricing in a 68% probability of a September rate increase by the Fed. The rising yields are also expected to pressure public and private sector debt servicing and negatively impact valuations, particularly in long-duration growth sectors.
