U.S. Treasuries are telling the market: money is getting more expensive.

What is really worth watching lately is not just the charts for U.S. stocks and crypto.

It is the yields on 5-year, 10-year, and 30-year U.S. Treasuries.

Many people know that rising Treasury yields suppress risk assets. But the three maturities represent completely different things.

5Y looks at corporate financing.
10Y looks at stock valuations.
30Y looks at long-term credit and fiscal conditions.

5Y is closest to the financing environment companies will face over the next few years.

U.S. companies rely heavily on corporate bonds, bank loans, and other forms of financing. When much of their debt matures, they need to borrow new money to repay the old.

Debt that was issued at 3% in the past may need to be refinanced at 5%, 6%, or even higher if the risk-free rate remains elevated.

High rates for a few days are not a major problem.

High rates for several months or even years are what really hurt.

More and more old debt enters the refinancing cycle → interest eats into profits → cash flow declines → buybacks and investment are reduced → layoffs and asset sales.

So when 5Y is high, it pressures companies’ future profits and cash flow.

10Y is the line I pay the most attention to when looking at U.S. stocks.

It is one of the most important valuation anchors for global risk assets.

When 10Y is only 2%, investors are willing to assign AI, semiconductor, and technology companies valuations of dozens of times earnings or even higher.

When 10Y approaches 5%, the market has to recalculate.

If buying Treasuries already offers a nominal yield close to 5%, why take on 20% or 30% volatility in stocks to buy companies trading at dozens of times P/E?

So AI demand can continue to grow, and earnings reports can remain strong, yet stocks can still fall.

The companies have not gotten worse.

Investors are simply no longer willing to pay such expensive prices.

So when 10Y is high, it is valuation that gets crushed.

What really makes me more cautious is 30Y.

30Y is no longer trading solely on whether the Federal Reserve will cut rates at its next meeting.

Behind it are America’s long-term fiscal deficits, Treasury supply, inflation, energy prices, and the price at which global investors are willing to continue lending money to the U.S.

If 30Y stays above 5% for an extended period or continues to hit new highs, it means the market is demanding higher long-term risk compensation.

This will ultimately be transmitted to long-term corporate financing, real estate, mortgages, infrastructure, and the entire financial system.

So when 30Y is high, it pressures long-term balance sheets and the credit system.

The truly dangerous combination is:

5Y↑ + 10Y↑ + 30Y↑

5Y tells you that corporate money is getting more expensive.

10Y tells you that stock valuations are becoming harder to sustain.

30Y tells you that long-term funding for the entire financial system is also getting more expensive.

If oil prices rise at the same time, the chain becomes even more complete.

Oil prices↑ → inflation pressure↑ → room for rate cuts↓ → Treasury yields↑ → stronger dollar → declining global liquidity.

It will ultimately reach the crypto market.

Because crypto runs on liquidity.

When money is cheap.

BTC → ETH → SOL → altcoins.

Capital spills over layer by layer into higher-risk areas.

When money starts getting more expensive, the process completely reverses.

Altcoins die first → ETH/SOL come under pressure → BTC proves relatively resilient → liquidity continues to deteriorate → BTC eventually catches down.

That is why sometimes BTC does not appear to have fallen much, while altcoins are already littered with corpses.

The story has not suddenly ended.

The water level has started to fall.

From now on, remembering a few things is enough when watching the markets.

5Y looks at financing.
10Y looks at valuation.
30Y looks at long-term credit.
The dollar looks at global liquidity.
BTC/ETH look at risk appetite.

Stocks can continue making new highs, and BTC can continue holding up.

But if 5Y, 10Y, and 30Y continue making new highs simultaneously,

I will become increasingly cautious.

Because Treasuries will not tell you what day the market will collapse.

They will only tell you in advance that money is getting more expensive.

Once refinancing starts coming due in concentrated waves and leverage begins to contract,

stocks will be hit on valuation.
Crypto will be hit on liquidity.

In the end, it is all the same pool of money that gets hit.
