Global bonds are facing intense pressure driven by the latest surge in energy prices, inflicting losses on investors who bet that the worst sell-off of the year was over, and putting central bank credibility to the test.

Benchmark UK government bond yields recorded their longest streak of daily closes above the 5% level in nearly two decades this week, while yields on 10-year German bonds reached their highest levels since 2011, and their Japanese counterparts approached levels not seen by markets since the 1990s.

Additionally, the yield on the 30-year US Treasury bond settled just below its highest level since 2007, while short-term Treasury yields hit their highest levels in over a year this week.

Biggest Monthly Loss Since March

The sell-off has become so severe that it pushed the average yield on the Bloomberg Global Aggregate Government Bond Index, which tracks investment-grade sovereign bonds, to 3.68%, surpassing the peak recorded three years ago to reach its highest level since the 2008 global financial crisis. The benchmark index is currently heading toward its largest monthly loss since March.

The simultaneous pressure on short- and long-term bond yields comes ahead of a weekend that could witness further geopolitical developments. A series of major central bank rate decisions are also expected next week, including the Federal Reserve, the Bank of Japan, and the Bank of England.

Repercussions of Falling Bond Prices and Rising Yields?

The continuation of the bond market sell-off would heighten concerns about the unsustainability of global debt levels, raise corporate borrowing costs worldwide, and increase the risk of investors shifting away from equities.

Torsten Slok, chief economist at Apollo Global Management in New York, commented on the rise in yields across sovereign debt markets, saying: "There are several similar forces currently influencing the market."

He explained: "Oil prices are rising. This creates problems for the Bank of England, it creates problems for the Federal Reserve, and by the way, also for the European Central Bank."

Middle East Tensions Weigh on Bonds

Global debt markets have faced severe pressure this year due to higher energy prices resulting from the conflict in the Middle East. While crude prices retreated in June as a ceasefire between Iran and the US materialized, renewed hostilities drove oil prices up again this month, with Brent crude climbing above $100 a barrel on Thursday.

The bond market also faced pressure from the resilience of the US economy, amid the continued strength of the labor market and growth figures.

This has contributed to changing expectations for the Federal Reserve's monetary policy path this year, shifting from interest rate cuts to rate hikes.

New Fed Chair's Approach

Traders are also beginning to digest new Federal Reserve Chair Kevin Warsh's approach to restructuring the central bank's communications to reduce forward guidance, increasing the likelihood of any monetary policy shift happening sooner than expected.

Bets on a rate hike during the Federal Reserve's monetary policy meeting on July 28 and 29 have risen, with current market-implied probabilities pointing to a one-in-three chance (33%).

Mark Cabana, head of US interest rate strategy at Bank of America, said: "We know Warsh doesn't want to provide forward guidance to the market, and that's fine." "But in that case, the market will have a greater capacity to price the outcome it thinks the Federal Reserve should take, or price an outcome that might prompt the bank to consider raising interest rates."

The Federal Reserve scaling back forward guidance could mean its next decision might come as a surprise regardless of the direction it takes.

Above all, Warsh and his colleagues must convince markets that the central bank is fully in control of inflation.

Bond Index Down 20% From Peak

Bond funds continue to suffer the fallout after policymakers worldwide were caught off guard by the post-pandemic inflation surge. The benchmark Bloomberg global bond index remains down about 20% from its peak in early 2021.

Analysts at Barclays, including Anshul Pradhan, wrote in a research note on Thursday: "A rate hike would prompt markets to reprice the terminal interest rate at higher levels, leading to a flattening of the yield curve." They added: "As for the decision to keep interest rates unchanged, if not well explained, it will likely lead to higher long-term interest rates."

Weak Yen Pushes Up Japanese Bond Yields

Bond prices are also falling in Asia. Japanese 10-year bond yields continue to climb amid concerns that the central bank is not raising rates quickly enough to curb inflationary pressures stemming from the declining yen.

This comes despite policymakers signaling openness to accelerating the pace of rate hikes ahead of their anticipated meeting next week.

Traders in the UK will focus on Bank of England projections and Governor Andrew Bailey's comments to confirm expectations of two rate hikes by the end of the year. The British central bank is balancing the risks of higher energy-driven inflation against a weak labor market and slowing growth.

Benchmark bond yields in Australia are the highest among developed economies, with risks pointing to the possibility of further gains.

Next week's inflation data and a speech by Reserve Bank Governor Michele Bullock could reinforce expectations for a fourth rate hike this year.

Central Banks Relying on Historical Data

Pooja Kumra, a strategist at TD Securities in London, said: "Central banks face a complex situation because all confirmed economic data is now only measuring past performance." She added: "They are in a tough spot, and this is a situation the whole world is experiencing right now."

BlackRock's iShares 20+ Year Treasury Bond ETF was among the hardest hit, widely used by investors to gain exposure to the performance of long-term US government debt.

The price of the exchange-traded fund dropped by nearly 5% over the past month, pushing its cumulative losses to more than half of its 2020 value.

Atsi Sheth, chief credit officer at Moody's Ratings in New York, said: "We believe we have entered a new macroeconomic phase." This means "structurally higher inflation, the resulting higher interest rates, alongside widening fiscal deficits, and the potential escalation of global uncertainty with the burdens passed onto government balance sheets."
