Why it matters: Most investors see the Treasury replenishing its cash buffer as a routine post–debt ceiling exercise, but history shows it can be one of the fastest ways to quietly drain liquidity from markets. A rapid rebuild of the Treasury General Account (TGA – the government’s bank account) doesn’t create new money - it siphons reserves out of the banking system as investors buy treasury bonds with cash. Thus, with the TGA set to nearly double in just weeks, we’re about to see whether markets can handle another liquidity squeeze without something breaking.
Now the Deep Dive: Are U.S. financial conditions about to tighten even further? I believe so.
In that piece, I explained why this matters (when the cash cushion disappears, banks lose reserves, and funding markets can become stressed).
But now, there’s another big risk for reserves. . .
I’m talking about the Treasury itself.
Back in July, the government said it would rebuild its TGA to $850 billion by the end of September - almost double its ~$400 billion level in late July. Moves this big and that fast have only happened a handful of times in the last decade.
Now you may be thinking, “Why should anyone care?”
Because the TGA is basically the government’s checking account at the Fed. When it refills that account, it doesn’t create new money - it drains it out of the banking system until it’s spent.
Normally, the RRP would soak up some of that drain. But with the RRP empty, there’s no buffer. The full weight of the TGA rebuild now falls directly on bank reserves - which are already shrinking under the Fed’s quantitative tightening (QT).
That’s a dicey situation – because the last time reserves slipped below ~10% of GDP was in 2019 when repo markets froze up, overnight funding rates spiked, and the Fed briefly lost control of short-term rates.
Put simply, every bond the Treasury issues to refill its checking account works like a suction pump - pulling cash out of banks and tightening funding markets. And it’s happening in a huge amount and at a time when excess liquidity is running dry.
Most people don’t pay attention to “monetary plumbing” (who can blame them?). But when the pipes run dry, the consequences hit markets, funding, and eventually asset prices.
I’ll keep you in the loop as this develops.

What you need to know: French bond markets are flashing red as debt climbs, deficits widen, and politics unravel - stoking fears that a core pillar of the eurozone is starting to crack2.
Why it matters: France’s debt-to-GDP ratio is ~113%, paired with one of the largest primary deficits in the developed world. As the eurozone’s second-largest economy, it carries significant weight. But unlike Japan, France doesn’t have a captive domestic investor base - more than half of its sovereign debt is foreign-owned. That leaves it exposed. If capital keeps fleeing and foreign investors pull back, borrowing costs could spike and trigger a doom loop between French banks, government debt, and the broader economy.
Now the Deep Dive: I wrote to you two weeks ago highlighting the U.K.s financial troubles. But it’s certainly not alone in Europe.
In fact, France’s case is potentially even worse.
Here’s the gist why:
“Sure,” some say, “But France’s debt isn’t as big as, say, Japan’s (nearing 240% of GDP). So why worry?”
Well, for starters, France doesn’t borrow in yen from a loyal domestic base (most Japanese debt is owned internally). It borrows in euros - and more than half its debt is held by foreign investors who can sell at a moment’s notice – such as rotating capital to Germany or Italy instead. That’s the key risk.
Secondly, France runs chronic trade deficits - whereas Japan runs surpluses. Surpluses give Japan extra savings that stay at home and fund its debt. Deficits drain money out of France, leaving fewer domestic buyers and forcing it to rely on fickle foreign investors.
France - long seen as the mom of Europe if Germany is the dad - is starting to look more like the canary in the coal mine. Its fiscal unraveling would not stay contained to Paris. With so much debt owned abroad, a French crisis would quickly become a European and even global problem.
Now, don’t expect France to implode. The ECB still has tools. And France still borrows in a reserve currency (the euro), and intervention would come fast to prevent contagion.
But with bond markets waking up across the world - from the U.K. to Japan to the U.S. - France may be the one to watch most closely.
