Your morning briefing, the business news you need in just 15 minutes.

On today's podcast:

(1) An upcoming Supreme Court ruling on the legality of the sweeping tariffs that President Donald Trump rolled out in April, briefly sending shockwaves through markets, looms as one of the next big tests for US stocks and bonds.

(2) US President Donald Trump could find out as soon as Jan. 9 whether the Supreme Court will strike down a key portion of his tariffs campaign. The court is considering whether Trump can use an emergency law that had previously never been wielded to impose import taxes, and its decision could be included in an upcoming opinions release on unspecified cases.

(3) Rio Tinto Group is in talks to buy Glencore Plc to create the world’s biggest mining company with a combined market value of more than $200 billion, a little over a year after earlier talks between the two collapsed.

(4) China’s consumer-price growth accelerated last month thanks largely to higher food costs, as deflationary risks stalk the world’s second-biggest economy in the absence of more forceful stimulus measures.

(5) Trump administration officials have discussed sending payments ranging from $10,000 to $100,000 to Greenland residents, Reuters reports, citing four sources familiar with the matter.
