"Ukrainian President Volodymyr Zelensky, not Putin, is the leader who should be invited to the G20 gathering. Zelensky leads a country of incredibly brave and determined people whose fight for their freedom should inspire us all," writes David J. Kramer in his open letter.

It’s striking how easily everyone understands that Trump’s hostility/pressure is responsible for Canada’s strategic pivot towards Europe but there are still those who don’t see that Russia’s hostility/pressure on Ukraine drove it gradually towards Europe/NATO.

El domingo vino y se fue y nunca llegó el pedido de facultades legislativas del Ejecutivo. Fue herido de muerte con las observaciones que pusieron los propios equipos ministeriales. Primer desastre.

Peru has had one of the lowest inflation rates in Latin America over the last two decades. What makes this strange is the context: permanent political crises, 8 presidents in a decade, massive pension withdrawals, repeated capital flight episodes. And yet the currency remained remarkably stable.

Not just legal authority. Technical capacity: identifying vulnerabilities, designing instruments, acting quickly, correcting imbalances before they become crises.

That is where the Peruvian central bank gets its power. When it buys or sells dollars, it actually changes the effective supply of dollars inside the domestic financial system. And because external replacement is costly and delayed, intervention has real effects.

Javier Loza
@insanidadpublica.com

The interesting implication is institutional. Many people assume the best public institutions are the ones that intervene the least. Peru’s central bank suggests something different:its strength comes precisely from its capacity to intervene effectively.

Peruvian banks do not need dollars occasionally.They need them permanently. Their deposits are in dollars.Many loans are in dollars.Large parts of their balance sheets depend on continuous dollar funding.

Javier Loza
@insanidadpublica.com

Of course banks can still borrow dollars internationally. But not instantly. And not for free. As demand for external funding rises: spreads increase, conditions tighten, funding becomes more expensive. Arbitrage exists, but with frictions.

But why does this even work? Standard economic theory would predict that it shouldn’t. Under the simplest models, if a central bank buys dollars, private actors simply obtain more dollars abroad. Arbitrage eliminates the effect.

Javier Loza
@insanidadpublica.com

Peru is different because of one key feature: dollarization. For decades, households and firms: saved in dollars, borrowed in dollars, bought property in dollars. The dollar stopped being just a foreign currency. It became a parallel domestic currency.

Not interventionist in the classic sense: printing money recklessly, financing fiscal deficits, fixing prices, directing industries. But interventionist in a more sophisticated way: it constantly intervenes in financial markets to shape monetary conditions.

It buys and sells dollars.Adjusts reserve requirements.Regulates FX forward positions.Creates new instruments when vulnerabilities emerge. Peru’s monetary stability was not produced by “leaving markets alone.” It was produced by active and technically sophisticated intervention.

The standard explanation is:“Peru’s central bank is technically competent.” That’s true, but incomplete. The more interesting point is that Peru’s central bank is also one of the most interventionist institutions in the country.

On May 26, 2014, the last flight departed Donetsk Airport. 7 hours later, the first battle began. The fight for Donetsk Airport lasted until January 2015. The terminals were reduced to rubble. But Ukrainian soldiers—the cyborgs—held on until the end. Today marks 12 years since the first battle.

Day after day, russia deliberately targets and murders Ukrainians for daring to exist. The world watches. The world forgot that unpunished evil spreads. Today in Odesa, while Europe enjoys Easter holidays, russia killed a 30 year old woman and her 2.5 year old daughter, and a 53 year old woman.

Hegseth indicates reopening the Strait of Hormuz is not a core US objective: "We've been willing to lead, President Trump has led the entire time, but it's not just us. You might want to start learning how to fight for yourself."

I don't know how many physicists would hold this view, but since determinism is a feature of classical physical THEORIES, rather than of the universe, I feel that they have no more to say about free will than, say, economic theories. The only reason people think they do is because they work better

At seven I asked why Pinocchio wasn't considered real from the start. Nobody thought the question worth answering. Decades later, Karl Friston's neuroscience, a first love, and the unsettling consistency of large language models brought it back.
