So much for that “one-time correction.” The People’s Bank of China let the yuan drop again overnight, fixing the currency 1.6% below Tuesday’s close, following the 1.9% devaluation heard around the world a day ago.

It then had to intervene to keep things from getting out of hand.

Cue continued freakout for global markets.

Deutsche Bank, for one, is predicting the yuan is overvalued by around 10%, so if the yuan continues to weaken, things could yet get a lot darker for markets. And stocks aren’t dealing well with the new China reality they’ve seen so far.

Jani Ziedins of the Cracked Market blog says the U.S. market’s reaction — the S&P 500 fell 1% Tuesday, and futures are pointing sharply lower on Wednesday — looks a bit overdone. Still, he says, it’s understandable given the reasons behind it — fears of much bigger economic problems in China. Good news? “...if a crumbling Chinese economy cannot bring down this market, then nothing will and all we can do is hang on and enjoy the ride,” he says.

Ziedins says watch the next two days to get some insight into the market’s psyche. Either selling is revving up to drop this market to levels not seen in years or this emotional purge will exhaust itself, and a rebound will follow, he predicts. Our chart of the day shows just how long it’s been since the S&P 500 has had a decent correction.

But if death crosses and visions of rotting Apples are disturbing your sleep, you aren’t alone. ”The darkest horizon ever approaches, infused with Chinese black coal,” predicts the Fly, blogging for iBank Coin. It’s time to be cautious, he says. More on that here.

The call

SocGen’s permabear, Albert Edwards, is among those who have been calling this yuan devaluation for years. So a little gloating is in order, we guess.

Weighing in on yesterday’s move in a fresh note, Edwards predicts China’s actions will release a tidal wave of deflation in the West. “Make no mistake, this is the start of something big, something ugly,” he says. And while western nations have been sighing with relief over abating deflation pressures, Asia has presented a “puss-filled boil” that needs to be lanced, he warns.

“We have long believed that we are only one misstep from outright deflation in the West, with core inflation in both the U.S. and the eurozone at just 1%. We expect the acceleration of EM devaluations to send waves of deflation to the West to overwhelm already struggling corporate profitability and take us back into outright recession,” Edwards says.

With that, he predicts “a financial market rout every bit as large as 2008,” along with sub-1% 10-year Treasury yields TMUBMUSD10Y, 0.664% as core inflation drops below zero.

Note that Edwards has had his share of misses. As CNBC recently pointed out, the S&P 500 has gained nearly 50% since the strategist warned in September 2012 that the U.S. was in recession and a Wall Street rout was coming. Read that story here, where he also predicts a repeat financial crisis.

The buzz

Standard & Poor’s Ratings Services has put Berkshire Hathaway’s BRK.A, -2.46% BRK.B, -2.37% ratings on review after news that Warren Buffett’s conglomerate will buy Precision Castparts US:PCP for about $32 billion. The S&P is partly worried about how Berkshire will finance the deal.

“What’s interesting is that Buffett is buying this stock after it’s had several great years. Since 1978, PCP is up over 158,000% to the S&P 500’s 2,100%,” notes Crossing Wall Street’s Eddy Elfenbein.

The FDA chewed out Kim Kardashian over a “misleading” Instagram selfie about a morning sickness drug. Meanwhile, watch this news anchor flip out over the mere mention of that family’s name:

GE GE, -7.70% is selling $8.5 billion of healthcare-related loans and its Healthcare Financial Services U.S. lending unit to Capital One for about $9 billion.

The chart

Short Side of Long blogger Tiho Brkan reminds us that the S&P 500 is in one of the longest stretches in its history — nearly 4 years — without a meaningful correction. He’s watching to see if the index drops below its 200-day moving average support of around 2,075. Pressures’s on as the S&P 500 has traded above its 200-day moving average for 183 out of the last 187 weeks.

Yesterdays’ tumble for the S&P 500 and futures calling for another rout this morning mean the bears could be ready to take control, at least for a while, says Brkan. Read the full blog here.
