Five Things You Need to Know to Start Your Day

Good morning. A landmark corporate tax pact, caution on easing restrictions and meme stocks continue to grab attention. Here’s what’s moving markets.

The Group of Seven rich nations secured a landmark deal that could help countries collect more taxes from big companies and enable governments to impose levies on U.S. tech giants. The deal satisfies a demand from the U.S. for a minimum corporate tax rate of “at least 15%” on foreign earnings and will pave the way for levies on companies in the countries in which they operate, rather than just those they are based in. Note, however, that key details need to be nailed down and the full implementation could take years with a need for more countries to sign up. Ireland, for example, has already expressed concerns given the hit its revenue would take.
