1/ ABOUT THE USE OF SILVER vs COPPER IN SOLAR PANEL,
LONGi SWITCHING,
AND THE DIFFERENTIAL PROCESS OF SOLAR PANEL COSTS

(falling PV energy to produce PV in a feedback loop)
What would be the impact for Solar Panels manufacturers of switching from Silver to base metals? 2/ Most current research and industrial sources discuss that switching to copper would result in 0.8%-1% loss in conversion (e.g., copper-metallized cells can be within ~1% efficiency of silver-based ones).:

Copper-metallised cells are within ~1% efficiency of silver counterparts — TNO / international research: tno.nl/en/newsroom/20… tno.nl/nl

SunPower / research comparison (copper vs silver metallisation): sunpropower.com/news/industry-… sunpropower.com

In that research, fully copper-metallised cells had slightly lower efficiency (e.g., ~23.08% vs 23.79% for silver), indicating about 0.7% — 0.8%+ efficiency difference in some test cases.

STRUCTURED REASONING ON OIL DEMAND FOR 2026 AND BEYOND
a.
2023-2024 LOWEST GROWTH IN OIL DEMAND OUTSIDE OF A RECESSION
b.
DEMAND FOR ROAD TRANSPORTATION WAS THE DRIVER OF TOTAL GROWTH IN OIL DEMAND BUT IS NOW FLAT
c.
A STRUCTURAL SHIFT : OIL DEMAND GROWTH WAS BEFORE DOMINATED BY GROUND TRANSPORTATION
d.
TRUCKS WERE DRIVING OIL DEMAND WITHIN THE TOTAL GROUND TRANSPORATION, BUT THE SHARE OF TRUCK IN $OIL DEMAND IS UNDER ATTACK
e.
CHINA TRUCKS : TRANSPORTATION WENT FROM THE MAIN DRIVER OF OIL GROWTH TO NEUTRAL:
f.
EUROPEAN OEMs ON SHARE OF EV IN TRUCK SALES BY 2030: 50-60%
g.
TRUCKS IN INDIA
h.
VERY LARGE IMPACT FROM E-BIKES
i.
CONCLUSION: LOOKING INTO 2026 AND BEYOND 2/16 DEMAND FOR ROAD TRANSPORTATION WAS THE DRIVER OF TOTAL GROWTH IN OIL DEMAND BUT IS NOW FLAT
In 2024, chemical feedstocks & aviation each accounted for around half of oil demand growth in energy terms (in volumetric terms, the share of feedstocks was higher, at around 70%).

LITTLE REMINDER
In the cash flow statement, non cash expenses like stock compensation are added back and non cash gains are substracted, nothing special just a bit of education for the non-specialists.

There are problems with debt absorption.

1/23 BESSENT THE HEDGE FUND FARMER
As I was reading the piece from Joseph Wang on repo, I remember my readings from different sources and notably from the BIS on systemic risk that showed up in April 2025.

In fact the FED is forced to backstop the dgeneracy of the repo market and hedge fund. The Negative haircuts on UST decried as a source of systemic risk by the BIS.
x.com/FedGuy12/statu…

So what are hedge funds doing with REPO in present of a large primary deficit? 2/23 THE CORE MECHANISM (Simplified)

The U.S. government is spending $2 trillion more than it collects each year → it must issue $2 trillion in new Treasury bonds/bills annually.

Who buys all these Treasuries?
Not just pension funds or foreign central banks (who pay with cash).

A huge chunk is bought by hedge funds, proprietary trading desks, and dealers—but they don’t use their own cash.

Instead, they use leverage:
They borrow cash overnight in the repo market.

They use the newly bought Treasury as collateral for that loan.

This lets them control $100 of Treasuries with only $5–$10 of their own capital. (and in fact with negative haircut as explained by the BIS and it’s a key point)

hy do they do this?

Mainly to run the cash-futures basis trade:
Long the actual Treasury (bought with repo cash),

Short the corresponding Treasury futures contract.

Profit if the two prices converge (which they usually do… until they don’t).

We will explain why they didn’t and it’s structural

The catch: This trade only works if repo funding is cheap and reliable.

And because trillions of dollars of these trades exist, they create massive, ongoing demand for repo loans—not once, but every single day, since repo is often rolled overnight.

It’s that every new Treasury issued is potentially fuel for another leveraged trade, which needs more repo financing.

More deficit → more Treasury issuance → more leveraged buying → more demand for repo.
The lenders of repo cash (money market funds, banks) are finite.

As they run out of “easy” cash (e.g., from the Fed’s RRP facility), they demand higher rates to lend.
Repo rates rise above the Fed’s Interest on Reserves (IOR)—a red flag that funding is getting tight.

1/25 The Lessons of fiat money from the XVIIIth century

For someone using classical economics who has abundant archives about the widespread use of fiat currencies at the end of the 18th century, 2/25 ...the wording used by the financial press of today is very weird. People talk about gold rising?

Let’s review what Henry Thornton says about the possibility of the BoE lending too much money to the government.

1/20 PROVING THAT BITCOIN IS A LIQUIDITY DECOY WITH SIMPLE DIFF EQUATIONS.
“HODL” on to your socks. (a bit technical)

ALSO The Fed is semi-lying, in fact, about “We would lose control of interest rates without IOR.”

docs.google.com/document/d/1n1… 2/20 Well, the opposite is true (long term), in fact, when the portion of interest-receiving reserves converges to 1.
IOR is convenient in the short term but lethal long term.

Maybe, but there is a precedent in 1885 2/25 After the 1873 Franco-Prussian war, there was first a credit expansion.

1/22 YIELD-PIGGING AND BUGS IN THE WINDSHIELD
Credit problems in history are almost ALWAYS due to yield pigging BTW.

(There is evidence of that when looking at investment-grade private credit versus CCC private.)
But let me explain first.
What is yield-pigging? 2/22
Say you are operating in a strategy like risk arbitrage, where you have to arbitrage merger-arbitrage spreads (the difference between the current price and the deal value).

Shanghai Gold Exchange, assayed, audited, secure, physical gold warrants volume. Image 2/8 (quick reminnder context)
YOU CAN SKIP THIS ONE IF YOU ALREADY KNOW ABOUT IT

The FX as reserves had three iterations, the post 1922 system with both GBP and USD politically forced as reserves with a bogus price convertibility (not at all a Gold standard, becausee a Gold standard implies letting the Gold flow and forbids using FX as reserves)

The Bretton Woods system post WWII which is a copy cat of the 1922 arrangement with again a bogus price convertibility but no Gold flow or convertibility just by everyday person.

The Bretton Woods II which severed any link to Gold and politically coerced the G-7 not to dump their exess USD trade surplus into Gold but forced them to do vendor financing and recycle those into UST.
