Global bond markets came under renewed pressure on Thursday as government borrowing costs surged to multi-decade highs across the United States, Europe and Japan. The move reflects a broader reassessment of inflation, economic growth and future interest rates, while rising yields are increasing financing costs for governments, companies and households.

US Treasury Market Reaches a New Pressure Point

The benchmark US 10-year Treasury yield climbed to 5.34%, its highest level since 2002, extending a sharp selloff that has made the third quarter the bond market’s most difficult period in decades. The yield increased by 87.1 basis points during the September quarter, representing its largest quarterly rise since 1994.

The 30-year Treasury yield also moved above 5.65%, reaching its highest level since 2002. Because Treasury yields serve as a global reference point for borrowing costs and asset valuations, the increase has implications well beyond the US government bond market.

Higher yields generally translate into higher financing costs across the economy. Companies face more expensive debt issuance, mortgage borrowers encounter higher borrowing costs, and governments must allocate more of their budgets toward interest payments when debt is refinanced.

Global Bond Markets Face Similar Pressures

The US move has been accompanied by significant selling across other major government bond markets. French 10-year yields approached 5% as investors assessed the government’s budget plans, while UK 30-year borrowing costs crossed 6%, reaching their highest level since 1998.

Japanese government bond yields have also continued to rise, extending a multi-quarter trend as investors adjust to a different inflation and monetary-policy environment after decades of unusually low borrowing costs.

The synchronized increase suggests that the latest bond selloff is not being driven by a single country’s fiscal or monetary outlook. Instead, markets are responding to a combination of higher energy costs, stronger growth expectations and concerns about the amount of government and private-sector borrowing required to finance investment.

AI Investment Adds Competition for Capital

One important structural factor is the rapid expansion of artificial-intelligence and data-center investment. The construction of large computing facilities requires substantial amounts of capital, increasing competition for funding at a time when governments are also issuing significant quantities of debt.

At the same time, stronger economic growth can create an unusual cross-asset dynamic. Robust growth supports corporate earnings and can benefit equities, but it can also reduce expectations for monetary easing and push long-term bond yields higher. The result is a more demanding environment for interest-rate-sensitive assets.

Higher Yields Increase the Pressure on Global Markets

For investors in Israel and global markets, the central issue is whether elevated yields represent a temporary repricing or the beginning of a longer period of structurally higher borrowing costs. The answer will depend on inflation, energy prices, central-bank policy, economic growth and government borrowing requirements.

Markets will also monitor whether higher yields begin to materially weaken credit demand, business investment or consumer activity. If borrowing costs remain elevated, governments and companies may face increasing pressure to manage financing requirements, while equity valuations could become more sensitive to the higher return available from government bonds.
