Enough with the surveys and polls, traders appear to be in "wait and see" mode as equities hold steady ahead of a closely watched Brexit vote. "Anyone that wants to call this referendum with confidence is extremely foolish," said John Curtice, professor of politics at Strathclyde University. "The contest is very close to 50-50." Politicians on both sides of the debate will be making their last arguments today ahead of polling stations opening tomorrow at 7:00 a.m. London time.

Just in case there was still anybody holding out for a July rate hike, Janet Yellen quashed that idea yesterday in her Humphrey-Hawkins testimony. Mostly repeating the memes from the recent FOMC policy meeting and her press conference, Yellen cited "considerable uncertainty" about the economic outlook, and the potential for a Brexit vote to shake up the markets. She testifies again today, this time before the House Financial Services Committee.

Puerto Rico is being sued in New York by a group of hedge funds claiming it's illegally using an emergency fiscal-crisis law to dodge payments that are supposed to be guaranteed by the island's constitution. While Governor Alejandro Garcia Padilla has not yet implemented a temporary debt moratorium, many speculate he will soon because the territory is expected to default on a payment of nearly $2B on July 1.

Acting Brazilian President Michel Temer has authorized the transfer of 2.9B reais ($849M) from the federal government to the state of Rio de Janeiro, which is struggling with a fiscal crisis less than two months before the Olympic Games.

North Korea fired two ballistic missiles off its east coast overnight in what appears to be the most successful test of its mid-range Musudan rocket to date.

The bankruptcy petition of mobile phone carrier Oi (NYSE:OIBR), the biggest ever in Brazil, poses no threat to the country's state banks or the wider financial system, Finance Minister Henrique Meirelles told Globo News.

Volkswagen's top management and supervisory board are expected to get an earful from shareholders today as the automaker hosts its first annual shareholders' meeting since its emissions scandal erupted in September.

BlackBerry is also holding its annual general meeting this morning, with executives likely to face questions about the future of the company's hardware business. The one-time smartphone leader has been struggling in recent years and its first Android-powered phone, the Priv, has so far failed to boost sales. BlackBerry's (NASDAQ:BBRY) software and services operations, on the other hand, have performed better, with revenue in the category last quarter jumping 106% Y/Y.

Samsung Electronics plans to invest $1.2B in the U.S. over the next four years on "Internet of Things" technologies.

Facing hefty compensation costs and falling sales, Mitsubishi Motors (OTC:MMTOY) is predicting a net loss of ¥145B ($1.4B) for 2016 in the wake of its mileage-cheating scandal.

McDonald's has received more than half a dozen bids for thousands of its China and Hong Kong stores in a deal that could be worth about $3B.

A federal judge in California has allowed a lawsuit accusing Starbucks (NASDAQ:SBUX) of deliberately underfilling lattes about 25% less than their advertised sizes.

A separate class-action in April accused the coffee giant of putting too much ice in cold beverages, leaving consumers with just over half the amount they paid for. Starbucks called both lawsuits "without merit."

U.S. senators are pushing for a compromise gun control bill, a day after they failed to advance four gun measures following last week's mass shooting in Orlando.
