Why Bond Yields Are Rising in All Major Countries — Except China

UPSC Syllabus: Gs Paper 3 – Indian economy

Introduction

Government bond yields are rising across major economies, increasing borrowing costs for governments, households and businesses. Rising oil prices, inflation concerns, growing public debt and increased borrowing for Artificial Intelligence (AI) investments are contributing to this trend. However, China is experiencing falling bond yields. This contrast reflects differences in inflation, domestic consumption, economic growth and investment patterns, with important implications for borrowing costs and economic stability.

What Are Government Bonds and Bond Yields?

1. Government Bonds: These are loans given by investors to governments, which are generally considered relatively safe borrowers because investors expect them to repay their debt.
2. Bond Yields: Bond yields represent the returns investors expect from lending money to the government. They change with bond prices: when prices fall, yields rise, and when prices rise, yields fall.
3. Link with Borrowing Costs: Rising government bond yields generally increase borrowing costs across the economy because governments set a key benchmark for other borrowers. This can make loans more expensive and slow economic growth.

Recent Trends in Bond Yields

1. United States Records High Yields: The 10-year US Treasury yield reached 5.34%, its highest level since 2002, while its third-quarter rise approached 90 basis points.
2. Multi-Decade Highs in Major Economies: Bond yields reached multi-decade highs in Germany, the United Kingdom, Japan and France, reflecting rising inflation concerns and government borrowing needs.
3. Changes in Ten-Year Bond Yields: Between June and September, average ten-year bond yields increased by 0.52 percentage points in the United States, 0.50 in Germany, 0.40 in the United Kingdom and 0.34 in Japan.
4. Increase in South Korean Yields: South Korea’s average 10-year government bond yield increased from 4.18% in June to 4.45% in September, reflecting the wider upward movement.
5. Growth in World Trade: Global trade growth has strengthened because of the information technology investment boom, which has increased US imports of capital goods and supported trade in Mexico, Korea, Canada and Indonesia.

Major Factors Driving Bond Yields Up

1. Rising Oil Prices and Inflation: Renewed increases in oil prices linked to US–Iran tensions have raised inflation concerns, leading investors to expect further interest rate increases.
2. Expectations of Higher Interest Rates: Investors demand higher returns when inflation rises because it reduces the purchasing power of future repayments, while central banks raise interest rates to contain price increases.
3. Growing Government Debt: The United States’ public debt has exceeded $40 trillion, while debt-to-GDP ratios have reached or exceeded 100% across the Group of Seven (G7) economies, except Germany.
4. Higher Government Borrowing Requirements: Governments face rising borrowing and spending needs, increasing concerns about debt sustainability and the cost of future interest payments.
5. Rising Borrowing for AI Investments: Five major technology companies—Alphabet, Amazon, Meta, Microsoft and Oracle—issued $220 billion in debt during 2026 to finance data centres and AI models, more than double their combined issuance in the previous year.
6. Demand for Higher Returns: When governments and companies seek more loans, investors can demand higher interest rates to supply the required funds, pushing bond yields upward.
7. Bond Vigilantes and Fiscal Discipline: Bond vigilantes are investors who demand higher returns from governments they consider financially irresponsible, putting pressure on policymakers to control public debt and inflation.

China: An Exception to the Global Trend

1. Falling Bond Yields: Unlike major economies experiencing rising yields, China has seen its government bond yields decline, reflecting different domestic economic conditions and investor behaviour.
2. Low Inflation and Deflation: China’s consumer inflation rate was 0% in 2025, compared with 0.2% in both 2023 and 2024, while inflation is expected to reach only around 1% in 2026.
3. Limited Pressure to Raise Interest Rates: Low inflation reduces the need for China’s central bank to increase short-term lending rates, unlike central banks responding to rising prices elsewhere.
4. Slower Economic Growth: China’s growth has moderated over the past decade, replacing earlier double-digit growth rates and reducing the demand pressures that typically contribute to higher inflation.
5. Export-Led Growth and Weak Domestic Consumption: China relies heavily on foreign demand for its exports, while domestic consumption remains weaker than policymakers would prefer, limiting inflationary pressure within the economy.
6. Excess Savings and Limited Investment Options: China has excess savings but fewer attractive investment opportunities because of the property market slowdown and restrictions on overseas investment.
7. Higher Demand for Government Bonds: Chinese investors increasingly buy government bonds as safe investments, raising their prices and lowering yields; however, these falling yields also signal weak domestic demand and economic concerns.

Consequences of Rising Bond Yields

1. Higher Government Debt-Servicing Costs: Rising yields make refinancing existing debt more expensive, with the United Kingdom’s interest bill reaching almost 4% of economic output, roughly twice its pre-pandemic decade average.
2. More Expensive Household Loans: Higher bond yields influence mortgage, student and car loan rates, making borrowing costlier and reducing households’ ability or willingness to spend.
3. Pressure on Businesses and Economic Growth: Higher borrowing costs make business investment less attractive and can reduce spending, slowing economic activity across the wider economy.
4. Pressure on Government Spending: Increasing interest payments absorb public funds that could otherwise support areas such as AI, defence and clean energy, creating difficult budgetary choices.
5. Effects on Stock Markets and Investors: Higher bond yields can make stocks less attractive compared with bonds, while hedge funds operating across multiple markets may face additional financial pressure.

Way Forward

1. Reduce Government Debt: Governments should take concerted steps to reduce public debt, as high debt burdens increase investor concerns and borrowing costs.
2. Control Inflation: Policymakers should contain inflation because investors demand higher returns when they believe inflation is not being managed effectively.
3. Boost Economic Growth: Governments should strengthen economic growth to improve their ability to manage debt and bring down long-term borrowing costs.
4. Use Bond Purchases During Market Stress: Governments can use bond buybacks, while central banks can purchase government bonds to address severe market stress and disorderly increases in borrowing costs.
5. Maintain Fiscal Discipline: Governments should follow responsible borrowing and spending policies to reassure investors and reduce pressure from bond vigilantes.
6. Recognise the Limits of Central Bank Support: Governments should address their underlying debt problems instead of relying on central banks to rescue their bond markets.

Conclusion

Rising bond yields reflect inflation concerns, higher oil prices, public debt and borrowing for AI investments. They raise financing costs for governments, households and businesses and can slow economic growth. China’s falling yields reflect low inflation, weak domestic consumption and excess savings. Long-term relief requires debt reduction, fiscal discipline and stronger growth.
