2. China says using its US bond holdings as a weapon in the trade war would be akin to 'playing with fire.' "We don't want to cause any financial instability in global markets," Cui Tiankai, China's ambassador to the US, told Reuters. "This is very dangerous — this is like playing with fire."
3. A top US regulator pours more cold water on a bitcoin ETF. "What investors expect is that trading in that commodity that's underlying the ETF is free from the risk or significant risk of manipulation," Jay Clayton, the chairman of the US Securities and Exchange Commission, said at Coindesk's Consensus conference in New York on Tuesday, according to CNBC. "Those kinds of safeguards don't exist in many of the markets where digital currencies trade."

8. Stock markets around the world are gaining ground. Hong Kong's Hang Seng (+1.33%) led the gains in Asia, and Germany's DAX (+0.24%) is out front in Europe after Larry Kudlow, President Donald Trump's top economic adviser, said there was a "good possibility" the US and China could reach a trade agreement at the G20 summit in Argentina this weekend.
