Government bond yields have surged around the world, raising the cost of borrowing for governments, businesses, and households alike. Benchmark government bonds in major economies reached multi-year highs on Tuesday, with the US 10-year Treasury yield climbing to its highest level since January 2025. Japan’s 10-year bond yield briefly touched 3 percent for the first time since 1996, signaling a major shift in global fixed-income markets.
Finance Minister Francois-Philippe Champagne said Canada’s borrowing costs are being held in check by strong investor confidence despite global market turmoil, according to Yahoo Finance. He noted that Canada has seen $8 billion in foreign investment into government bonds during the second quarter of this year. Champagne added that while Canada is not immune to global disruptions, the country’s financial position remains solid enough to handle current volatility. The Canadian government has also been taking steps to maintain stability in the short and long term, according to Champagne.
Meanwhile, Australia’s government is facing higher borrowing costs as its 10-year bond yield hit a 15-year high after years of low interest rates, according to a report from The Conversation. Mortgage holders in Australia have already seen interest rate increases over the past year due to actions by the Reserve Bank of Australia. But the impact is not limited to households — businesses and governments are also feeling pressure from rising rates. Australia’s federal government debt recently passed A$1 trillion, contributing to higher interest payments for the country’s public sector.
The main reason behind these increases is growing government debt and rising demand for returns from investors. Governments issue bonds to raise money for spending that exceeds tax revenue, and the more debt they carry, the higher the interest rates must be to attract buyers. In the United States, national debt has grown to more than $40 trillion — a figure that is more than 20 times the size of Australia’s economy. This level of debt is pushing up interest rates globally, as investors are becoming more cautious about the long-term sustainability of government finances.
Treasury Secretary Scott Bessent has tried to reduce borrowing costs by buying back some of the US government’s own debt. However, these buybacks had only a temporary effect on market rates, as investors concluded that underlying factors like rising inflation and increased issuance still drive interest costs upward. Experts say no amount of financial engineering can reverse the trend of higher interest rates in the medium to long term.
The situation is not limited to the US — countries around the world are seeing rising bond yields. Central banks like the Reserve Bank of Australia can influence short-term interest rates but cannot control longer-term bond yields directly. If the RBA were to cut rates sharply, it might actually raise expectations of inflation and push up longer-term bond yields instead. This is because central banks can only manage short-term borrowing through tools like the cash rate, not long-term market rates that are set by investor demand.
The US has historically enjoyed a special advantage in global markets due to the dominance of the dollar and trust in its government bonds. This allows the US to issue large volumes of debt without needing to raise interest rates significantly. But even this advantage is being tested by growing fiscal deficits and rising corporate borrowing for AI development.
Rising yields are also affecting equity markets, especially sectors like artificial intelligence where high growth expectations are already priced in, biz.heraldcorp.com reported. Analysts warn that continued increases in bond yields could lead to a correction in stock prices and broader financial instability.
The global bond selloff is being fueled by several factors including geopolitical tensions, higher inflation expectations, and growing government and corporate debt issuance. In particular, rising oil prices due to conflict in the Strait of Hormuz have added to inflation fears.
This environment is making it harder for heavily indebted nations to manage their finances and service existing debts. The US national debt has surpassed $40 trillion last month, and its fiscal deficit continues to widen, increasing pressure on interest rates.
Investors are demanding higher returns to offset the erosion of purchasing power caused by inflation. Central banks aim to keep inflation in check, which helps stabilize long-term interest rates. The Reserve Bank of Australia has set an inflation target of 2–3% to guide its monetary policy.
Despite these efforts, the global trend shows that rising bond yields are becoming a persistent challenge for governments and businesses worldwide.
