Is this the beginning of the global financial collapse? No, seriously. That is the topic I want to debate.
Most of the stores Walmart is closing, are "Walmart Express". Those are their smaller stores in more urban areas.
Walmart competes almost entirely on price, and competing on price is a hard business. They've been able to do it so long by being the biggest retailer, and by having such big stores. They can buy in such large quantities that they can get cheap prices, and they have a dense supply chain.
But once the rural and suburban areas in the US were saturated, they started expanding into cities with smaller stores, and expanding overseas with acquisitions, and they don't have a competitive advantage in either of those markets. At the same time, online retailers like Amazon have been doing way better than physical retailers, both on price and convenience. Amazon is stealing market share from Walmart, Macy's, and other large stores.
So no, Walmart's store closings has little to do with the global state of the economy. In fact, really cheap stores like Walmart and dollar stores tend to do better than other stores during recessions. Wealth concentration has made the middle class smaller, and so high-end and low-end stores have received more customers while middle stores have been in a tough spot.
The real bad indicator of global economic problems is the price of oil. It is now below $30.00 a barrel. This is a indication of the slowdown of the worldwide, including, the US economy.
That's more of an oversupply problem than a demand problem.
China's demand dropped, and the US has had an unusually warm December, but the bigger global issue is supply. Over the last several years, supply kept going up, because OPEC kept producing, and less conventional sources like oil sands and shale oil ramped up, increasing producing from places like the US and Canada. Supply has spiked over the last five years or so. And now, investors are taking into account the likelihood that Iran will be able to start supplying the world with oil again, which is yet another increase in supply.
Usually when supply outpaces demand, OPEC reduces supply to keep prices high. But this time they didn't do it, because they don't want to lose market share to the U.S., and so they've kept production going full steam to try to make the US reduce their production.
