Asian markets just lost over $650 billion in a single session. Here's what's actually driving the selloff:

Bond yields are spiking across the US, Japan, and Korea at the same time. Higher yields make borrowing more expensive and signal recession risk to investors.

Trump said there are no active talks with Iran, killing hopes for a peace deal. That keeps oil prices elevated, which matters because most of Asia's oil flows through the Strait of Hormuz.

Growth is already slowing. US GDP missed expectations, and so did Japan's. Higher oil prices and rising yields are pushing inflation expectations up just as growth weakens—a bad combo.

Semiconductor stocks got crushed in the US overnight, and that weakness carried straight into Asia. Major Asian indexes are heavily weighted in AI and chip names, so when semis fall, the whole region feels it.

This isn't panic. It's markets repricing risk in real time as multiple headwinds hit at once.
