The market is still climbing.
But underneath the surface, multiple warning signs are flashing at the same time.
Here are the numbers investors are watching.
1. Margin debt hits $1.42 trillion
Investors have borrowed a record $1.42 trillion to buy stocks.
The bigger warning is the speed.
Margin debt surged 53.7% year over year, reaching growth levels similar to periods before major market peaks like 2000, 2007, and 2021.
The peak itself is not usually the problem.
The problem is when leverage starts reversing and forced selling begins.
What keeps me awake at night?
This.
One of the oldest froth gauges on Wall Street: the year-over-year change in margin debt. How fast investors are borrowing money to buy stocks.

2. The dollar is strengthening
The U.S. Dollar Index (DXY) is around 101, showing renewed dollar strength.
A stronger dollar tightens global liquidity because foreign borrowers with dollar debt face higher costs.
If the dollar keeps climbing, pressure can spread through global markets.
3. The yen is under pressure
The USD/JPY is around 162 yen per dollar, leaving the yen near its weakest levels in decades.
Japan’s currency weakness is raising concerns about intervention and potential stress in global carry trades that rely on cheap yen funding.
A disorderly unwind could hit risk assets quickly.

4. Government debt is reaching historic levels
Global government debt has climbed to roughly 100% of global GDP.
The concern is that investors may eventually demand higher yields to hold that debt.
Higher yields mean higher borrowing costs for governments, businesses, and households.
Cheap money becomes harder to maintain.
U.S. national debt has now climbed above 100% of GDP for the first time since World War II.
That means the country now owes more than the total value of everything it produces in a year, a level typically seen only in major crises or wartime economies.

5. AI valuations face a reality check
AI spending continues at a massive pace, with companies pouring billions into chips, data centers, and infrastructure.
The question is whether future profits can justify today’s valuations.
The BIS has warned about AI uncertainty, debt fragility, and financial risks.
China will crash the US stock market this year.
They're dumping SOTA open-source models on the US, nearly as good as the frontier labs, basically free.
Nobody can refuse cutting a $100M AI bill down to $5M.

Employment in AI-linked sectors is contracting:
Over the last 3 months, AI-affected sectors posted an average monthly decline of -11,000 jobs.

6. Consumers are running out of room
U.S. credit card debt is near a record $1.25 trillion.
The savings rate is hovering around 2.6% to 3.0%.
More households are using debt while having less cash available for emergencies.
That makes consumers much more vulnerable to another shock.
7. Inflation is still eating into real incomes
The headline wage numbers can look positive.
But if inflation is rising faster than wages, purchasing power is falling.
For many workers, real wage growth is effectively negative.
That pressure is showing up in consumer sentiment, weaker discretionary spending, and households cutting back on nonessential purchases.
This is why the current market debate is getting louder.
It is not just about stock prices.
It is about whether record leverage, rising debt, currency stress, stretched valuations, and a pressured consumer can all coexist without eventually forcing a reset.
The market can ignore warning signs for a long time.
But it becomes dangerous when too many warning signs start pointing the same way.
