The New York Times reports:

There are not many certainties in the world of money, but this traditionally has been one of them: When life turns scary, people take refuge in American government bonds.

Investors buy U.S. Treasuries on the assumption that, come what may — financial panic, war, natural disaster — the federal government will endure and stand by its debts, making its bonds the closest thing to a covenant with the heavens.

Yet turmoil in bond markets last week revealed the extent to which President Trump has shaken faith in that basic proposition, challenging the previously unimpeachable solidity of U.S. government debt. His trade war — now focused intently on China — has raised the prospect of a worldwide economic downturn while damaging American credibility as a responsible steward of peace and prosperity.

“The whole world has decided that the U.S. government has no idea what it’s doing,” said Mark Blyth, a political economist at Brown University and co-author of the forthcoming book “Inflation: A Guide for Users and Losers.”

An erosion of faith in the governance of the world’s largest economy appears at least in part responsible for the sharp sell-off in the bond market in recent days. When large numbers of investors sell bonds at once, that forces the government to offer higher interest rates to entice others to buy its debt. And that tends to push up interest rates throughout the economy, increasing payments for mortgages, car loans and credit card balances.

Last week, the yield on the closely watched 10-year Treasury bond soared to roughly 4.5 percent from just below 4 percent — the most pronounced spike in nearly a quarter century. At the same time, the value of the American dollar has been falling, even as tariffs would normally be expected to push it up.

Other elements also go into the explanation for the bond sell-off. Hedge funds and other financial players have sold holdings as they exit a complex trade that seeks to profit from the gap between existing prices for bonds and bets on their future values. Speculators have been unloading bonds in response to losses from plunging stock markets, seeking to amass cash to stave off insolvency.

Some fear that China’s central bank, which commands $3 trillion in foreign exchange reserves, including $761 billion in U.S. Treasury debt, could be selling as a form of retaliation for American tariffs.

Given the many factors playing out at once, the sharp increase in yields for government bonds registers as something similar to when medical patients learn that their red blood cell count is down: There may be many reasons for the drop, but none of them are good. [Continue reading…]
