A dark cloud is gathering over the global economy, and this time the storm is brewing not in an emerging market but at the heart of the world's financial superpower - the United States.
For decades, US Treasury bonds have been regarded as the safest financial asset on earth, the ultimate refuge during wars, recessions and financial crises. Today, that sanctuary is under unprecedented pressure. Investors across the world are selling government bonds at a pace unseen in years, driving borrowing costs sharply higher and reviving fears that the global financial system is entering a new era of expensive money and mounting debt risks.
Warren Buffett once warned that long-term government bonds could become "a terrible mistake" when inflation outpaces interest rates. That warning now appears remarkably prescient.
From Washington to Tokyo, London to Frankfurt and Beijing, bond markets are flashing warning signals. Oil prices are climbing towards US$100 a barrel, stock markets are retreating, central banks are reconsidering interest-rate cuts, and investors are demanding higher returns before lending money to governments burdened with record debt.
This is no longer a Wall Street story. It is rapidly becoming a global economic story - and Bangladesh is unlikely to escape its consequences.
The Crisis Beneath the World's Safest Asset
The epicentre of the turmoil is the US Treasury market, the foundation of the international financial system. Treasury yields serve as the benchmark for global borrowing costs, influencing mortgage rates, corporate loans, currencies, commodity prices and capital flows across virtually every economy.
The United States now faces an unprecedented fiscal challenge. Its national debt has crossed US$40 trillion, while annual budget deficits remain above US$2 trillion. To finance this widening gap between spending and revenue, Washington must continuously issue massive volumes of Treasury bonds.
The growing supply of government debt is colliding with weakening investor appetite.
Bond prices have fallen sharply while yields have surged to multi-year highs, signalling that investors are demanding a much higher premium to finance the US government. The benchmark 10-year Treasury yield has climbed close to 4.8 per cent, threatening to breach the psychologically important five per cent threshold.
The crisis is largely self-inflicted. Years of expansionary fiscal policy, pandemic-era stimulus, rising military expenditure, tax cuts and the enormous financial cost of successive wars have left America's Treasury drowning in debt. Markets are increasingly questioning whether the world's largest economy can continue borrowing indefinitely without paying a much steeper price.
Adding fuel to the fire is renewed geopolitical instability.
The latest escalation in the conflict between the United States and Iran has reignited fears over the Strait of Hormuz, one of the world's busiest oil shipping routes. Brent crude has surged to around US$96 per barrel, with traders increasingly betting that oil could soon return to US$100.
Higher oil prices immediately translate into higher transportation, shipping, manufacturing, food and electricity costs across the world, complicating the inflation outlook for every major central bank.
Only weeks ago, investors expected the US Federal Reserve to begin cutting interest rates. Now markets are increasingly pricing in another rate hike and a prolonged period of tighter monetary policy.
Why China, Japan &Europe Are Changing the Global Financial EquationThe bond crisis is no longer solely an American problem. The world's three largest economic blocs - China, Japan and the European Union - are reshaping the global flow of capital in ways that could fundamentally alter international financial markets.
China has quietly been reducing its exposure to US Treasury securities for years. Once America's second-largest foreign creditor, Beijing has steadily cut its holdings to around US$750-800 billion while increasing purchases of gold and diversifying foreign exchange reserves.
China is unlikely to dump US Treasuries overnight because doing so would inflict billions of dollars in losses on itself and destabilise its export-driven economy. Yet its gradual retreat removes one of the largest traditional buyers of American debt precisely when Washington needs overseas investors the most.
Japan presents an even bigger challenge.
For nearly three decades, Japanese interest rates hovered close to zero, encouraging banks, pension funds and insurance companies to invest heavily in US government bonds. That era is ending. Japanese 10-year government bond yields have climbed above 3 per cent for the first time since 1996, making domestic investments increasingly attractive.
Instead of financing America's debt, Japanese investors are beginning to repatriate capital. That shift matters enormously because Japan remains one of the largest foreign holders of US Treasuries.
The European Union is facing its own bond market stress.
Eurozone inflation has accelerated again, forcing investors to expect tighter policy from the European Central Bank. Germany's 10-year bond yield has risen to its highest level in more than 15 years, while borrowing costs across France, Italy and other eurozone economies continue to climb.
Britain is experiencing similar pressure. UK government bond yields have surged above 5 per cent, approaching levels last seen during the 2008-09 global financial crisis as investors question Britain's fiscal discipline and growing public debt.
The verdict from global markets is unmistakable: governments across the developed world will have to pay significantly more to borrow.
The Return of the Bond VigilantesFinancial markets have revived a phrase largely forgotten since the 1990s - bond vigilantes.
The term does not refer to organised traders plotting against governments. It describes investors collectively refusing to lend cheaply to countries they believe are borrowing beyond sustainable limits.
Washington has already felt that pressure.
US Treasury Secretary Scott Bessent recently launched an extraordinary intervention by expanding buybacks of longer-dated Treasury bonds to restore liquidity and calm markets. Billions of dollars were injected into the market, temporarily lowering yields.
The relief lasted only days.
Investors resumed selling, wiping out the impact of the intervention and pushing Treasury yields back to their previous highs. Markets have effectively rejected Washington's attempt to engineer lower borrowing costs without addressing America's structural debt problem.
The message is blunt: financial engineering cannot replace fiscal credibility.
Another powerful force is intensifying the competition for capital.
America's technology giants - including Amazon, Google, Microsoft and Meta - are borrowing at an unprecedented pace to finance artificial intelligence infrastructure, hyperscale data centres, semiconductor facilities and clean-energy projects. Corporate bond issuance has reached record levels, meaning governments and multinational companies are competing for the same pool of global savings.
That competition is making capital more expensive everywhere.
Bangladesh in the Crossfire of the Global Bond StormBangladesh owns very little US Treasury debt, but it has enormous exposure to the consequences of rising global bond yields.
The first impact will come through imported inflation.
Bangladesh imports almost all of its petroleum products, LNG and a significant share of edible oil, wheat, fertiliser and industrial raw materials. If crude oil remains above US$95 or climbs beyond US$100, the country's import bill will rise sharply, widening the trade deficit and placing renewed pressure on foreign exchange reserves.
Higher fuel costs will cascade through transport, agriculture, manufacturing and consumer goods, making inflation harder to contain even if domestic demand remains weak.
The second shock will come through the US dollar.
Higher Treasury yields generally strengthen the dollar as investors shift capital into dollar-denominated assets offering higher and safer returns. A stronger dollar weakens the taka, making imports more expensive and increasing the cost of servicing Bangladesh's external debt.Every depreciation of the taka raises the government's debt-servicing burden and pushes up prices for imported essentials.
The third impact is capital flight from emerging markets.
When US government bonds offer attractive returns with minimal risk, global investors reduce exposure to frontier and developing economies. Foreign direct investment, portfolio investment and external commercial borrowing become harder and more expensive to secure.
This comes at a difficult time for Bangladesh, which is already experiencing slower FDI inflows, persistent balance-of-payments pressure and a fragile foreign exchange position.
The banking sector could face another external shock.
Already burdened with record defaulted loans, capital shortages and liquidity stress, Bangladeshi banks may face higher costs for syndicated loans, trade finance and overseas borrowing. Sovereign borrowing from international markets will also become more expensive as investors demand higher yields from emerging economies.
The capital market is equally vulnerable.
Higher global bond yields tend to reduce investors' appetite for equities because government securities begin offering attractive returns with lower risk. Foreign institutional investors become more cautious, while higher borrowing costs squeeze corporate profitability and discourage new investment.
Export-oriented industries may also feel the pain. Slower economic growth in the United States and Europe - Bangladesh's two largest export destinations - could weaken demand for garments, leather goods and other manufactured products. Remittance growth could also moderate if labour markets soften in migrant-hosting economies.
A New Era of Expensive MoneyThe turmoil sweeping global bond markets is far more than another bout of financial volatility. It signals a structural shift from an era of cheap money to an era where governments, businesses and households must pay significantly more for capital.
The United States is struggling to finance a US$40 trillion debt mountain. China is gradually reducing its dependence on US Treasuries. Japan is keeping more of its savings at home. Europe is paying its highest borrowing costs in more than a decade. Together, these developments are reshaping the architecture of global finance.
For Bangladesh, the risks are immediate and interconnected: higher fuel and food prices, a stronger US dollar, tighter external financing, weaker investment, pressure on foreign exchange reserves, costlier sovereign borrowing and renewed inflationary shocks.
The world's safest financial market is sending an unmistakable warning.
If confidence in the US Treasury market continues to weaken, the tremors will not stop at Wall Street. They will travel through global banks, commodity markets and currency markets before reaching Dhaka's banking system, stock market, foreign exchange market and, ultimately, the pockets of millions of Bangladeshi consumers.
