Government Bonds — The Safest Asset in the World

You think about your bank account. But banks fail, 2008 reminded everyone of that. Physical gold? Its price moves dramatically. Real estate? Illiquid, expensive to maintain, and prices do fall.

Most financial professionals arrive at the same answer. Government bonds from stable economies that control their own currency. US Treasuries. German Bunds. UK Gilts. Japanese Government Bonds.

The United States has never defaulted on its debt in the modern era. Not through the Great Depression. Not through two world wars. Not through the 2008 financial crisis. Not through any of the debt ceiling dramas that have periodically terrified markets. It has always paid. This near-certainty of repayment is the foundation of everything, why government bonds from stable economies are the asset against which every other asset in the world is measured.

This number is the benchmark against which virtually every other interest rate on earth is measured. Your mortgage rate is set with reference to it. Corporate borrowing costs are priced relative to it. Stock valuations are calculated using it. Every central bank in the world watches it.

Why? Because it represents the risk-free rate, the return you can earn by lending to the world''s most creditworthy borrower for ten years. Every other investment is evaluated against this. If you can earn 5% guaranteed by holding a Treasury note, a stock or corporate bond needs to offer significantly more than 5% to justify its additional risk. When the 10-year yield rises, the hurdle rate for every other asset rises with it. When it falls, that hurdle falls. When this yield moves significantly, everything else in global finance adjusts simultaneously.

The German 10-year Bund yield is the benchmark for the Eurozone. Germany is the most creditworthy sovereign in the euro area and its yield is the reference point for interest rates across all 20 countries sharing the euro. The spread between Italian or Spanish government bond yields and the German Bund, the peripheral spread, tells you in real time how nervous investors are about the fiscal health of weaker Eurozone members.

The UK 10-year Gilt yield is the benchmark for sterling interest rates. In September 2022 UK Gilt yields spiked violently following a controversial budget announcement, requiring emergency Bank of England intervention and causing one of the largest single-day moves in British pound history. Bond markets can and do bring governments to account faster than any election.

The Japanese 10-year Government Bond yield is unique. The Bank of Japan spent years artificially capping it, a policy called yield curve control, creating some of the most complex interactions between bond markets, currency markets, and central bank credibility of any market in the modern era.

As you move down the rating scale the probability of default increases and investors demand higher yields to compensate. A country rated BBB is investment grade. A country rated BB or below is what the market calls speculative grade.

Sovereign defaults do happen. Argentina has defaulted on its international debt multiple times. Greece required a debt restructuring in 2012 that imposed losses on private bondholders. Sri Lanka defaulted in 2022 amid a severe economic crisis. For traders in emerging market currencies and bonds, sovereign credit quality is one of the most important risk factors to monitor continuously.

The number traders watch most closely is the bid-to-cover ratio, how many dollars of bids were received for each dollar of bonds offered. A ratio of 2.5 means investors offered to buy two and a half times more bonds than were available.

When an auction produces a bid-to-cover ratio significantly below recent averages with bonds awarded at yields above expectations, it signals weak demand. Yields tend to rise after a weak auction. For forex traders this can be a subtle bearish signal for the dollar. Strong auctions tend to support the dollar because foreign investors buying Treasuries need to acquire dollars first.
