I understand that bond market issues drove the stock market decline and then I guess the subsequent increase.

But why did the 90-day tariff pause make that happen?

If Japan and/or China are dumping their Treasury bonds because they believe the US financial markets are unstable, why does a temporary pause on increased tariffs make them feel like the US bond market is a safe investment?  Especially in light of the U.S. increasing China's tariff to 145%? Aren't Japan and China going to continue to dump their bonds?
