In early August 2026, the global bond market is experiencing a rare capital migration. While the 30-year US Treasury yield has climbed to its highest level since 2007 and the belief in 'risk-free' US Treasuries is beginning to loosen, international large asset management institutions such as UBS Asset Management, Barings, and Aviva Investors have, as if by prior agreement, turned their eyes to Europe—German government bonds, French government bonds and even Southern European bonds are quietly becoming the new 'safe havens' for global capital. Is this a short-term tactical rebalancing or a long-term change in global bond allocation logic? It is worth investors' in-depth interpretation.
Why Are US Treasuries Unpopular? Policy Uncertainty Becomes the Biggest Hidden Worry
The root of the fading halo of US Treasuries lies in the erosion of its 'certainty premium'. Last week, the 30-year US Treasury yield once soared to its highest level since 2007, underperforming German government bonds, with the spread widening to the widest level this year. The market's doubts about the credibility of Fed Chair Kevin Warsh in fighting inflation are deepening—the Fed kept the benchmark rate unchanged last week, Warsh's vague stance on key issues, plus foreign media reports that he is considering reducing the frequency of policy meetings, have made investors question the Fed's determination to bring inflation back to the 2% target.
Deeper pressure comes from the fiscal side. The expansion of defense spending and the social welfare burden brought by population aging continue to increase, while geopolitical turmoil, climate change, and trade barriers may all keep inflation at a high level for longer. Crude oil has risen by about 15% since the end of February, becoming the main driver of interest rate repricing this year. When fiscal deficits and inflation stickiness reinforce each other, the holding cost and risk premium of long-term US Treasuries naturally rise.
Europe's Relative Certainty: Low Growth, Low Inflation and a Credible Central Bank
In sharp contrast to the US, Europe presents 'relative certainty' in the eyes of investors. Brian Mangwiro, investment manager at Barings, summed up the institutional mentality: 'Reducing the allocation of US Treasuries and British government bonds and shifting to European assets has full logical support. If seeking a more stable institutional and political environment while facing a low-growth, low-inflation landscape, Europe is a reasonable destination.'
Kevin Zhao, global head of sovereign fixed income and foreign exchange at UBS Asset Management, was even more blunt: 'Europe has no inflation problem, which is completely different from the UK and the US. In the long run, Europe is low-growth, low-inflation, but has a highly credible independent central bank.' He believes that the German 10-year government bond yield breaking through 3% last month provided a good buying opportunity—market expectations for the European Central Bank's tightening are clearly excessive.
Data can also confirm this. The swap market shows that traders are betting that the European Central Bank will raise rates by 25 basis points this year, with a 60% probability of another rate hike; by the middle of next year, the market's cumulative rate hike pricing is about 70 basis points. Aviva Investors believes this expectation 'has gone too far', so the overweight position of Eurozone bonds is more attractive. Craig Veysey, portfolio manager at Guinness Global Investors, added that the European Central Bank tends to sacrifice potential growth to more forcefully control inflation, 'weaker economic growth is actually beneficial for bonds'.
Institutions Voting with Their Feet: Latest Rebalancing Roadmap
In addition to verbal statements, the rebalancing actions of real money are more worthy of attention:
- UBS Asset Management and Guinness Global Investors continue to increase German government bonds;
- Barings reduces US Treasuries and shifts capital to Italian, Spanish and French bonds;
- Aviva Investors said that the overweight position of Eurozone bonds is quite attractive;
- JPMorgan Asset Management has reduced long-term Italian government bond exposure and instead sees opportunities in French government bonds.
It is worth noting that this is by no means a simple 'buy Europe' safe-haven trade. Kim Crawford of JPMorgan Asset Management has reduced exposure to long-term Italian government bonds, citing the risk of the September budget negotiations and cracks in the ruling coalition of Prime Minister Meloni; on the contrary, she sees opportunities in French government bonds—the French 10-year government bond yield is nearly 80 basis points higher than German bonds of the same type, and the premium has become attractive. 'Europe is attractive, although the upside is less than the UK. European policy is in a neutral zone, while the UK is still in a tightening zone.' Crawford said.
Global Perspective: Japanese and British Bonds Have Their Own Troubles
Looking at the global picture, the 'alternative options' for safe-haven assets seem to be far from calm. Japanese government bonds continue to be under pressure due to yields rising to multi-decade highs, and recent Japanese 10-year government bond auctions have encountered the weakest demand since May 2025, and exchange rate intervention measures may only provide temporary relief. In the UK, investors remain cautious before Prime Minister Burnham announces his first budget at the end of October—his government is facing the major challenge of raising military funds and adult social care funds, and the 30-year UK government bond yield is already at the highest level among developed markets.
Of course, Europe is not a paradise. Eurozone bonds are also affected by the global sell-off caused by the Iran war and the resulting energy crisis, and there are significant differences in fiscal pressure and political risks among countries. Once investors decide to shift from the US to Europe, 'selecting countries to buy bonds' becomes the new key test—the fiscal discipline of Southern European peripheral countries and the supply capacity of core countries will determine the attribution of relative returns.
Allocation Implications: Bond Investment Enters the 'Selection Era'
For global asset allocators, this round of capital migration sends three signals. First, the policy paths of major global central banks are increasingly divergent, the traditional framework of anchoring solely to US Treasuries is failing, and the investment portfolio needs more diverse sources of interest rate risk. Second, the weight of 'country selection' in bond investment has significantly increased—European bonds such as German, French and Italian bonds have completely different risk pricing, and active management capabilities have become scarce again. Third, in the new normal of inflation stickiness and fiscal expansion, duration management and volatility budgeting are far more important than before, and a dumbbell position structure remains a systematic solution to high volatility.
Looking ahead to the future, whether the US Treasury yield can peak and fall, the key still lies in the oil price trend, the Fed's policy communication and the game of the US fiscal budget; whether the relative attractiveness of European bonds can continue depends on the tightening rhythm of the European Central Bank and the evolution of the political situation in various countries. For ordinary investors, instead of betting on the rise and fall of a single market, it is better to follow the trend of 'diversification and decentralization' of capital flows and recalibrate the risk-return ratio of bond positions globally. After all, when the definition of 'safe haven' itself is changing, only discipline and balance can be the unchangeable way to navigate volatility.
