When government national debt grows too large to fix with spending cuts or higher taxes, there are really only two ways out of the dilemma: a hard default or inflation.

Option 1: The Hard Default

A hard default means the government simply stops paying back what it owes. For the US, the fallout would be severe. Investors would no longer treat Treasury bonds as ultra-safe. They would demand much higher interest rates to keep lending, and those higher borrowing costs would ripple through the entire economy.

I don’t expect this to happen. It’s the loud, messy option, and policymakers have a strong incentive to avoid it.

Option 2: The “Soft” Default

The quieter alternative is inflation. Think of it as a soft default, because it erodes the dollar’s purchasing power instead of breaking the government’s promise outright.

Here’s how it works. The government still pays its debt back in full. But it pays with dollars that are worth less than the ones it borrowed. Over time, that makes the debt far easier to manage.

The catch is who absorbs the cost. Your salary and your savings quietly lose buying power while the debt shrinks.

Japan: A 30-Year Case Study

Japan shows what this can look like in practice. For more than three decades, the country kept interest rates low and let inflation do its work. The result was that its debt became smaller relative to the size of its economy.

For ordinary people, though, the outcome was far less encouraging. Japanese salary earners are not wealthier than they were 30 years ago.

The Takeaway

Governments can manage debt through inflation without ever technically defaulting. But “managing” the debt doesn’t mean the cost disappears. It gets passed along to the people holding dollars, saving money, and earning paychecks.

That’s why it pays to understand this dynamic. If inflation is the likely path forward, protecting your purchasing power becomes a far more important part of your financial planning.
