Trading activity Sunday night shows the recent tumult on Wall Street will continue.

What's going on: The yield on the benchmark government bond continued its swift slide lower as nervous investors pile into the safe-haven asset, while pre-market trading pointed to steep declines for U.S. stocks. Oil prices dropped sharply.

Details: The yield on the 10-year Treasury note fell below 0.5% at one point on Sunday night.

  • There's been a massive move in yields in a short amount of time. Less than one week ago, the yield broke below 1% for the first time ever. At the beginning of the year, the yield was around 1.88%.
  • S&P 500 futures fell 5%. That’s the most the CME allows it to fall before curbing trading until the market officially opens on Monday. That limit was last hit more than three years ago.
  • Separately, the OPEC-Russia production-limiting pact fell through, prompting oil prices to collapse. The price of Brent crude fell more than 20%.

Driving the news: Coronavirus cases spiked in the U.S. over the weekend. Overseas, Italy shut down a key economic hub to contain the spread of the virus.

Democrats called on President Trump to disclose his tax returns following a New York Times report alleging he paid $750 in federal income taxes in 2016 and 2017 and nothing in 10 of the past 15 years.

Details: Trump said the report was "total fake news," that he's unable to release the returns as they're "under audit" by the IRS, "which does not treat me well." House Speaker Nancy Pelosi (D-Calif.) said in a statement the report "provides further evidence of the clear need" for a House lawsuit to access the tax returns and "ensure the presidential audit program is functioning effectively, without improper influence."

Firefighters in the western U.S. were facing "critical fire weather conditions," as a rapidly spreading new wildfire in Northern California prompted fresh evacuations Sunday.

Why it matters: Wildfires have burned a record 3.6 million acres in California this year, killing 26 people and razing over 7,600 structures, per Cal Fire. Utility provider Pacific Gas & Electric cut power to 11,000 customers early Sunday and planned outages for 54,000 others later in the day because of fire risks.
