Yesterday Japan’s government borrowed money on terms that require the lenders to pay rather than receive interest for ten years. And not only was that bond issue snapped up, it was vastly oversubscribed. This raises a lot of questions, the chief being “why would anyone voluntarily commit to something that’s guaranteed to lose money for a decade?”

The short, obvious answer is that the world’s central banks are creating so much excess cash that there seems to be nowhere else for it to go. The longer, but way more interesting and scary explanation is that capitalism as it used to function is over, and the result will be catastrophic.

Here’s an overview of those Japanese bonds:

Japan Sells 10-Year Bonds at Negative Yield For the First Time

(Bloomberg) – The Japanese government got paid to borrow money for a decade for the first time, selling 2.2 trillion yen ($19.5 billion) of the debt at an average yield of minus 0.024 percent on Tuesday.

The sale drew bids for 3.2 times the amount of the securities offered, the first increase in demand since an auction in December, according to the Finance Ministry. Japanese government bonds of as long as five years in maturity sold at an average yield below zero for the first time last month, after the Bank of Japan pushed yields lower across the curve with the announcement of negative interest rates Jan. 29.

“Demand was stronger than expected,” said Shuichi Ohsaki, chief rates strategist at Bank of America Merrill Lynch. “The outcome suggests there is ample demand before redemption of existing bonds in March.”

The benchmark 10-year bond yield dropped as low as minus 0.075 percent after the auction, matching a record. Yields on 20-year debt sank to an unprecedented 0.46 percent, while those on 30-year securities declined to an all-time low of 0.765 percent.

The JGB yield curve was the flattest on record at the end of last week, under pressure from the BOJ’s bond purchases, with the premium offered by 10-year securities over two-year notes narrowing to just 11.5 basis points.

The central bank buys as much as 12 trillion yen of the nation’s government debt a month.
