Central Bank Balance Sheet Runoff Hands Bond Yields to Private Buyers

Japan's 30-year government bond yield has climbed from effectively zero during the deflation era to record highs, and the mechanism behind that move is a change in who owns the debt. Balance sheet runoff removes the one buyer that never assessed whether a yield represented an attractive return, and hands pricing power to investors who do. The Bank of Japan bought Japanese government bonds for monetary policy transmission reasons, which made it relatively insensitive to price, and that process is now reversing. As its holdings shrink, banks, insurers, pension funds, foreign investors and households absorb the supply instead, and each of them requires compensation for the risk. The result is a long end that has backed up far more aggressively than the front, where rate expectations dominate.

Key Themes

• Bank of Japan holdings of Japanese government bonds peaked and have fallen since, as the balance sheet runs down.
• The Bank of Japan's share of outstanding Japanese government bonds has dropped back below half of the market.
• Long dated yields are at records while the central bank still owns roughly half the market and retains a perceived backstop.

Balance Sheet Runoff Strips Government Bond Markets of Their Price Insensitive Buyer

Quantitative easing created a buyer whose purchase decision had nothing to do with return, and the Bank of Japan is the clearest example of it. Its holdings of Japanese government bonds peaked before beginning a steady decline as the bank allows the balance sheet to run down, and its share of the market has fallen materially from that peak. "Central banks were enormous buyers of government debt. They bought for monetary policy transmission reasons, not because the yield represented an attractive return that made it relatively insensitive to price. But now that process is reversing", Scutt says. Consequently, the volume of paper that has to find a genuine home is rising at exactly the moment governments are running large fiscal deficits on top of already heavy debt burdens. Specifically, this is not a Japanese peculiarity, since other central banks have been letting bonds bought during quantitative easing mature and roll off their own balance sheets.

Private Investors Demand Real Compensation to Hold Long Dated Government Debt

According to Scutt, "more bonds have to be absorbed by investors who actually care about the price, their pain and the risks that they're taking", which is the practical definition of the handover now underway. Banks, insurers, pension funds, foreign investors and households each require payment for inflation risk, fiscal risk, supply risk and the outlook for rates over a 30 year horizon, and that payment is term premium. The gap between short dated and long dated Japanese government bond yields has widened well beyond what rate expectations alone would justify, evidenced by a long end that has moved far more than the front. Notably, record long term yields are being reached while the Bank of Japan still owns close to half the market and investors remain aware it retains the ability to step back in, so the true clearing level is arguably higher than the one on screen. As Scutt puts it, "Japan faces an uncomfortable trade off. Allow bond yields to rise, or risk more of the adjustment showing up through a weaker yen".
