The coronavirus is already disrupting the global supply chain, starting with these commodities

This is the web version of the Bull Sheet, Fortune’s no-BS daily newsletter on the markets. Sign up to receive it in your inbox here.

Happy Friday, Bull Sheeters. “Uncertainty” is the word of the day, reflected in the schizophrenic daily swings of the global markets. As I type, Asia is mixed, Europe, after a decent start, is down, as are the U.S. futures.

Tonight, at 11 p.m. London time, Brexit goes into effect. If you think that’s the end of that dispute, pull up a chair. I have a bridge to sell you.

We will get to Brexit another day. Today we’re going to talk coronavirus (213 dead, confirmed cases in 23 countries outside mainland China), and the significant impact it’s having on markets.

To recap: yesterday, the U.S. markets rebounded late in the day on the World Health Organization’s warning that the contagion situation is bad, but don’t panic. And hence we had the first, to my knowledge, “WHO bounce.” I’m calling it that. (The U.S. State Department probably killed and buried the “WHO bounce” hours later, advising Americans: “do not travel” to China.)

The projections for how bad this contagion could get are all over the place. My Fortune colleagues did an exhaustive job tallying all the companies—from Tesla to United Airlines —that have curtailed or shut down operations in China in recent days, or imposed employee travel bans. And Moody’s warns the coronavirus will impact global supply chains.

To see the short-term impact on the supply chain just look at commodity prices, which is the subject of today’s chart. China is a huge consumer of commodities, from copper to crude oil. Aluminum, steel, nickel, too. It’s building stuff at a pace that’s unfathomable to G7 nations. And so when China catches a cold, much of the commodities market sinks.

Commodities take a pounding

***

Commodities prices—with the notable exception of gold—are down across the board. As the chart above shows, the Bloomberg Commodity Index has plunged 6% since Jan. 17, when we got the first big outbreak disclosures. (That Bull Sheet made its newsletter debut right around then is merely a coincidence, dear reader.) Copper, Brent crude and palm oil, which China imports like no other country, are down even worse in that time.

I even find the swing in gold revealing. It’s up, but not by much, which might say something about investor uncertainty extending even into safe havens. So where are investors putting their money? What’s your coronavirus strategy? Drop me a line. Let me know.

Like Brexit, the coronavirus saga has only just begun.

Today's reads

Recession radar. You may have heard in recent weeks the terms "inverted yield curve" and "recession" in the same sentence. It's a fairly uncommon markets event, one that's overwhelmingly pessimistic. Why's that? Erik Sherman explains what it all means

15 seconds. Something suspicious happened yesterday in Blighty. 15 seconds before the Bank of England surprised the markets with its rates decision, the pound sterling took off. Coincidence? The UK's Financial Conduct Authority isn't so sure. It's opened an investigation into whether there was a leak.  

No clue. I appreciate the candor of Bridgewater Associate's Ray Dalio's missives on LinkedIn. Yesterday, he called himself a "dumb shit," admitting he has no idea how the markets will withstand the coronavirus contagion, and that he plans to study up on the great pandemics of the past. He then geeked out, charting the markets impact of the Swine flu, SARS, and the Spanish flu outbreaks of years past. Love the charts!

Market candy

Super Sunday. On occasion of this weekend's Super Bowl, S&P Global Market Intelligence shared with us a few data points about the big stock market winners and losers in select Super Bowl years. Warning: there's absolutely no correlation here, this is merely fun. For example, "when the teams in the Super Bowl combine to score at least 46 points, the stock market returns 15.8% on average (based on 28 years). If the final combined score is under 46, the average market return is just 7.3%."

I don't have a big preference this year, but this caught my eye: "The market has gained an average of 23.9% following each of the 49ers"—the Kansas City Chiefs face off against the San Francisco 49ers—"victories including the largest annual return in the Super Bowl era of 37.6% following Super Bowl XXIX in 1991."
