LONDON (Reuters) – Global markets have been pummeled yet again on Wednesday as President Donald Trump’s eye-popping 104% tariffs on China took effect and a savage selloff in U.S. bonds sparked fears that foreign funds were fleeing U.S. assets.

Here is an overview of all the market news you need to start your day. Mike is off today, but check out his latest column to find out why the yuan is making analysts across Wall Street rip up their recently revised dollar forecasts.

Today’s Market Minute

* China’s top leaders plan to convene a meeting as early as Wednesday to discuss measures to boost the economy and stabilise capital markets, people with knowledge of the matter said.

It’s a ‘bond story’ now

This week has brought crisis-era volatility to markets, erasing trillions of dollars in value from stocks and hitting commodities and emerging markets with force.

At the epicentre of the latest rout are U.S. Treasuries, effectively the backbone of the global financial system. The benchmark U.S. 10-year yield rose by as much as 26 basis points to a high of 4.515% in Asia, before the selloff abated, leaving it up 7.7 bps at 4.34%.

“Last week was an equity story but as ever, it’s moved from an equity story to the more important bond story,” Chris Beauchamp, chief strategist at IG, said. “This is the financial plumbing and clearly, the plumbing has begun to seize up.”

Potentially adding to the pressure on Treasuries is an auction of new 10-year notes later on today that could prove a crucial litmus test of investor appetite for U.S. government debt.

Meanwhile, the yield on the 30-year Treasury briefly spiked above 5% before dropping back below 4.9%.
