Japan must choose one of two bad options. Keep rates at zero to manage its massive debt but watch the yen collapse from inflation. Or, raise rates to save the yen but risk bankrupting the country with high interest payments on its 200%+ debt-to-GDP. There is no viable middle ground.

Facing stagnation since the 1990s, Japan's central bank and domestic institutions bought nearly all its debt. The U.S. is now on a similar path, aiming to inflate its debt away relative to GDP, with Japan providing a historical playbook for this soft default.

The long-term strategy is to resolve intergenerational wealth imbalances by keeping financing costs below inflation. This allows inflation to act as a "tax" on the vast bond holdings of baby boomers, effectively transferring wealth to fund new growth investments for younger generations.

While Japan executed a smooth, coordinated currency devaluation, Europe lacks the political unity and first-mover advantage. The Euro's decline will likely be a messy process, triggered by a series of political and debt crises rather than proactive policy.

When national debt grows too large, an economy enters "fiscal dominance." The central bank loses its ability to manage the economy, as raising rates causes hyperinflation to cover debt payments while lowering them creates massive asset bubbles, leaving no good options.

A government funding unsustainable promises has only three choices, all of which terminate in dead ends. It can tax harder, causing capital flight; borrow more, leading to a debt crisis; or print money, destroying the currency's value. Each path inevitably leads to economic ruin.

When Japan repatriates its trillions in foreign assets, it will create a massive capital hole in US and European markets. Rather than allowing a painful credit contraction, the Fed and ECB will respond predictably: by printing more money to fill the gap, reinforcing the global inflationary cycle.

The endgame for unsustainable government debt is not austerity but monetization. Albert Edwards argues that political weakness and fiscal incontinence will eventually force central banks to print money to cover debts. This 'fiscal dominance' will mark a return to the double-digit inflation levels of the 1970s.

Despite rising JGB yields relative to US Treasuries, the Yen is weakening, not strengthening. This is classic emerging-market price action, signaling that investors believe Japan cannot afford higher rates and will be forced to print money. This serves as a warning for other indebted Western nations.
