Recently, U.S. long-term bond yields have risen again. The yield on 30-year U.S. Treasury bonds climbed to around 5.18%, the highest level since July 2007; the 10-year Treasury yield also rose to near 4.67%, reaching its highest level since January 2025. 

Many people think bond yields are only related to the bond market.  
But in fact, long-term bond yields reflect the market's view on future funding costs.  
The market is beginning to worry: money in the future might remain expensive for a long time.  
That's why the market is becoming anxious. 

What's the difference between short-term and long-term bond yields?  
Short-term bond yields, such as those on 3-month, 1-year, or even 2-year U.S. Treasury notes, are more influenced by central bank policy.  
Markets use them to gauge whether the Federal Reserve will cut interest rates in the future or if rates will remain high. 

Long-term bond yields, such as those on 10-year and 30-year U.S. Treasury securities, reflect a more complex picture.  
They do not merely indicate current interest rates, but rather capture the market's expectations regarding future inflation, economic outlook, government debt, and funding needs. 

What's the problem with high long-term bond yields? 

First, government debt becomes more expensive.  
The U.S. government has long relied on issuing bonds to finance its operations.  
When long-term bond yields rise, it means the government will have to pay higher interest rates when borrowing in the future.  
If the debt level is already high, and interest costs increase further, fiscal pressure will naturally grow. 

Second, corporate financing has become more expensive.  
Companies often need to borrow money when setting up factories, purchasing equipment, conducting research and development, or acquiring other businesses. As borrowing costs rise, many investment plans must be reevaluated.  
Projects that were once worthwhile may no longer be profitable. 

Third, asset valuations need to be recalculated.  
When safer assets offer higher returns, investors will naturally demand more attractive returns from other assets such as stocks, real estate, and gold. 

In terms of stocks, highly valued companies tend to be more sensitive.  
This is because when funding costs rise, the market's patience for "future stories" diminishes. 

In the past, when interest rates were low, the market was willing to pay high prices for future earnings.  
But as bond yields rise, the market becomes more focused on whether a company is actually making money today. 

Gold is also affected. Although gold serves as a safe-haven asset, it itself does not generate interest. 

When long-term bond yields are low, the opportunity cost of holding gold is not high.  
But when long-term bond yields rise, investors tend to compare 

If safe-haven demand is strong enough, gold prices can rise.  
However, if bond yields and the dollar strengthen simultaneously, gold is likely to face pressure. 

The key is:  
Is the demand for safe-haven assets greater, or is the pressure from high interest rates greater? 

With long-term bond yields rising, the market is beginning to wonder: will the low-interest era return as quickly as expected?  
When such thoughts emerge, government debt servicing, corporate financing, stock valuations, and gold prices all need to be reassessed.
