Earlier this week, before first JPM (JPM) and then Wells Fargo (WFC) revealed that not all is well when it comes to bank energy loan exposure, a small Tulsa-based lender, BOK Financial (BOKF), said that its fourth-quarter earnings would miss analysts’ expectations because its loan-loss provisions would be higher than expected as a result of a single unidentified energy-industry borrower. This is what the bank said:

“A single borrower reported steeper than expected production declines and higher lease operating expenses, leading to an impairment on the loan. In addition, as we noted at the start of the commodities downturn in late 2014, we expected credit migration in the energy portfolio throughout the cycle and an increased risk of loss if commodity prices did not recover to a normalized level within one year. As we are now into the second year of the downturn, during the fourth quarter we continued to see credit grade migration and increased impairment in our energy portfolio. The combination of factors necessitated a higher level of provision expense."

Another bank, this time the far larger Regions Financial (RF), said its fourth-quarter charge-offs jumped $18 million from the prior quarter to $78 million, largely because of problems with a single unspecified energy borrower. More than one-quarter of Regions’ energy loans were classified as “criticized” at the end of the fourth quarter.

It didn't stop there and and as the WSJ added, "It’s starting to spread" according to William Demchak, chief executive of PNC Financial Services Group Inc. (PNC) on a conference call after the bank’s earnings were announced. Credit issues from low energy prices are affecting "anybody who was in the game as the oil boom started,” he said. PNC said charge-offs rose in the fourth quarter from the prior quarter but didn’t specify whether that was due to issues in its relatively small $2.6 billion oil-and-gas portfolio.

Then, on Friday, U.S. Bancorp (USB) disclosed the specific level of reserves it holds against its $3.2 billion energy portfolio for the first time. "The reason we did that is that oil is under $30" said Andrew Cecere, the bank’s chief operating officer. What else will Bancorp disclose if oil drops below $20... or $10?

It wasn't just the small or regional banks either: as we first reported, on Thursday JPMorgan (JPM) did something it hasn't done in 22 quarters: its net loan loss reserve increased as a result of a jump in energy loss reserves. On the earnings call, Jamie Dimon said that while he is not worried about big oil companies, his bank has started to increase provisions against smaller energy firms.

Then yesterday it was the turn of the one bank everyone had been waiting for, the one which according to many has the greatest exposure toward energy: Wells Fargo (WFC). To be sure, in order not to spook its investors, among whom most famously one Warren Buffett can be found, for Wells it was mostly "roses", although even Wells had no choice but to set aside $831 million for bad loans in the period, almost double the amount a year ago and the largest since the first quarter of 2013.

What was laughable is that the losses included $118 million from the bank’s oil and gas portfolio, an increase of $90 million from the third quarter. Why laughable? Because that $90 million in higher oil-and-gas loan losses was on a total of $17 billion in oil and gas loans, suggesting the bank has seen a roughly 0.5% impairment across its loan book in the past quarter.

How could this be? Needless to say, this struck us as very suspicious because it clearly suggests that something is going on for Wells (and all of its other peer banks), to rep and warrant a pristine balance sheet, at least until a "digital" moment arrives when just like BOK Financial, banks can no longer hide the accruing losses and has to charge them off, leading to a stock price collapse.

Which brings us to the focus of this post: earlier this week, before the start of bank earnings season, before BOK's startling announcement, we reported we had heard of a rumor that Dallas Fed members had met with banks in Houston and explicitly "told them not to force energy bankruptcies" and to demand asset sales instead.

We can now make it official, because moments ago we got confirmation from a second source who reports that according to an energy analyst who had recently met Houston funds to give his 1H16e update, one of his clients indicated that his firm was invited to a lunch attended by the Dallas Fed, which had previously instructed lenders to open up their entire loan books for Fed oversight; the Fed was shocked by what it had found in the non-public facing records. The lunch was also confirmed by employees at a reputable Swiss investment bank operating in Houston.

This is what took place: the Dallas Fed met with the banks a week ago and effectively suspended mark-to-market on energy debts and as a result no impairments are being written down. Furthermore, as we reported earlier this week, the Fed indicated "under the table" that banks were to work with the energy companies on delivering without a markdown on worry that a backstop, or bail-in, was needed after reviewing loan losses which would exceed the current tier 1 capital tranches.

In other words, the Fed has advised banks to cover up major energy-related losses.

 Why the reason for such unprecedented measures by the Dallas Fed? Our source notes that having run the numbers, it looks like at least 18% of some banks' commercial loan book' are impaired, and that’s based on just applying the 3Q marks for public debt to their syndicate sums.

In other words, the ridiculously low increase in loss provisions by the likes of Wells and JPM suggest two things: i) the real losses are vastly higher, and ii) it is the Fed's involvement that is pressuring banks to not disclose the true state of their energy "books."

Naturally, once this becomes public, the Fed risks a stampede out of energy exposure because for the Fed to intervene in such a dramatic fashion it suggests that the US energy industry is on the verge of a subprime-like blow up.

Putting this all together, a source who wishes to remain anonymous, adds that equity has been levitating only because energy funds are confident the syndicates will remain in size to meet net working capital deficits. Which is a big gamble considering that as we first showed ten days ago, over the past several weeks banks have already quietly reduced their credit facility exposure to at least 25 deeply distressed (and soon to be even deeper distressed) names.

However, the big wildcard here is the Fed: what we do not know is whether as part of the Fed's latest "intervention", it has also promised to backstop bank loan losses. Keep in mind that according to Wolfe Research and many other prominent investors, as many as one-third of American oil-and-gas producers face bankruptcy and restructuring by mid-2017 unless oil rebounds dramatically from current levels.

However, the reflexivity paradox embedded in this problem was laid out yesterday by Goldman who explained that oil could well soar from here but only if massive excess supply is first taken out of the market, aka the "inflection phase."  In other words, for oil prices to surge, there would have to be a default wave across the US shale space, which would mean massive energy loan book losses, which may or may not mean another Fed-funded bailout of US and international banks with exposure to shale.

What does it all mean? Here is the conclusion courtesy of our source:

If revolvers are not being marked anymore, then it's basically early days of subprime when mbs payback schedules started to fall behind. My question for bank eps is if you issued terms in 2013 (2012 reserves) at 110/bbl, and redetermined that revolver in 2014 ‎at 86, how can you be still in compliance with that same rating and estimate in 2016 (knowing 2015 ffo and shutins have led to mechanically 40pc ffo decreases year over year and at least 20pc rebooting of pud and pdnp to 2p via suspended or cancelled programs). At what point in next 12 months does interest payments to that syndicate start to unmask the fact that tranch is never being recovered, which I think is what pva and mhr was all about.

Beyond just the immediate cash flow and stock price implications and fears that the situation with US energy is much more serious if it merits such an intimate involvement by the Fed, a far bigger question is why is the Fed once again in the a la carte bank bailout game, and how does it once again select which banks should mark their energy books to market (and suffer major losses), and which ones are allowed to squeeze by with fabricated marks and no impairment at all? Wasn't the purpose behind Yellen's rate hike to burst a bubble? Or is the Fed less than "macroprudential" when it realizes that pulling away the curtain on of the biggest bubbles it has created would result in another major financial crisis?

The Dallas Fed, whose new president Robert Steven Kaplan previously worked at Goldman Sachs for 22 years rising to the rank of vice chairman of investment banking, has not responded to our request for a comment as of this writing.
