What to watch for today

The US Federal Reserve weighs in. The two-day Federal Open Market Committee meeting comes to an end. In light of disappointing retail sales, the central bank is more likely than ever to hold interest rates steady.

The UK announces its budget. Chancellor George Osborne is expected to unveil £4 billion ($5.6 billion) in further spending cuts, a $2-billion education package, and investment in huge rail and road infrastructure projects. He still plans to get rid of the deficit by 2020.

FedEx reveals its quarterly earnings. The delivery giant is expected to report revenue of $12.4 billion, compared with $11.7 billion a year earlier. FedEx and its ilk are often bellwethers for the wider economy.

While you were sleeping

Donald Trump sent “little” Marco Rubio packing… Trump won Florida, prompting the home-state senator to bow out of the race. But he lost to John Kasich in Ohio, which could lead to a contested convention this summer.

…and Hillary Clinton had a great night. The Democratic front-runner racked up a convincing series of victories in Florida, Illinois, North Carolina, and especially Ohio, leaving Bernie Sanders well behind. She also looks set to take Missouri.

Deutsche Boerse and London Stock Exchange agreed a $30-billion merger. Shares in both exchanges rose 2% with the announcement of a deal that would give the German exchange a majority shareholding, with LSE’s equity holders getting 45.6%. The deal needs regulatory approval and there’s still a chance Intercontinental Exchange could make a higher offer.

German power companies took their government to court. Eon, RWE, and Vattenfall argue they shouldn’t have to foot the bill for decommissioning their nuclear plants (paywall) and seek billions damages for what they say is an expropriation of their assets.

China announced a dual-growth plan. At the end of the 12-day National People’s Congress, Chinese premier Li Keqiang  said that China could implement its economic reforms without mass layoffs or derailing the nation’s growth trajectory, which is set at 6.5% over the next five years.

North Korea sentenced a US student to 15 years of hard labor. Otto Warmbier, a 21-year-old undergraduate at a Virginia university, was found guilty of “crimes against the state” for removing a political banner from a hotel. The sentence will further stoke tensions between Pyongyang and Washington.
