My chart for ICAEW this week is on the cost of government borrowing in the Eurozone, which on 4 September ranged from 2.17% for Danish 10-year bonds up to 3.59% for their Italian equivalents.
My chart this week is on the range of yields payable on 10-year government bonds by 18 out of the 20 countries in the Eurozone for which data is available.
The chart illustrates how investors in German 10-year government bonds (known as ‘bunds’) would have received a yield to maturity of 2.22% – or conversely the German government could have borrowed at an effective interest rate of 2.22% if issuing fresh debt at that point in time. Yields on German bunds are used as benchmark rates for government debt not just in the Eurozone, but globally.
Just one country in the Eurozone has a lower 10-year bond yield than Germany, which is Denmark at 2.17% on 4 September, which is a 0.05 percentage points or 5 basis points (bp) ‘spread’ below the benchmark bund rate.
While quoted yields move up and down all the time, sometimes by quite large amounts, spreads are much less volatile, providing an insight into how debt investors perceive the relative risks of investing in different countries’ sovereign debt.
The next lowest yields were the Netherlands at 2.51%, with a spread of 0.29 percentage points above bunds, and Finland at 2.59% (+0.37%). This is then followed by Ireland on 2.67% (+0.45%), Austria on 2.71% (+0.49%), Belgium on 2.80% (+0.58%), Portugal on 2.82% (+0.60%), France on 2.93% (+0.71%), Slovenia on 2.94% (+0.72%), Cyprus on 3.00% (0.78%) and Spain on 3.02% (+0.80%). There is then a small jump to Greece on 3.28% (+1.06%), Slovakia on 3.30% (+1.08%), Malta on 3.34% (+1.12%), Lithuania on 3.36% (+1.14%) and Croatia on 3.41% (+1.19%).
The highest yield for investors among Eurozone countries – and hence the highest borrowing cost for its government – is Italy with 3.59%, which is 1.37 percentage points above the effective interest rate at which Germany could in theory borrow.
Comparing the bond yields in the Eurozone provides an insight into the relative strengths and weaknesses of these countries’ public finances and economies given that they all share a currency, a central bank base interest rate (currently 3.75%), and are all in the EU Single Market and Customs Union. Comparing yields with other currencies, such as the UK’s 3.95% for example (not shown in the chart), needs to take other factors into account, such as the UK’s much higher central bank base rate of 5%.
The chart also reports the government debt to GDP levels of each country for the second quarter of 2024 according to Eurostat, which may help explain why Denmark (with debt/GDP of 34%) pays a significantly lower borrowing cost than Spain (109%).
However, debt/GDP doesn’t explain all of the differences, with the 10-year yield on Greek government debt (debt/GDP 160%) of 3.28% for example being significantly lower than the 10-year yield on Italian government debt (debt/GDP 138%) of 3.59%.
Not shown in the chart are Estonia (debt/GDP 24%) and Latvia (45%), both of which tend to borrow at shorter maturities.
The lack of a firm correlation between debt/GDP and bond spreads should not be surprising as debt/GDP is a relatively crude measure of public finance strength or weakness. It excludes most government assets and non-debt liabilities, the funded or unfunded nature of their social security systems, as well as a country’s medium- and longer-term economic prospects and the perceived stability of that country’s government. These are all factors debt investors take into account when deciding the level of risk that they are willing to accept when investing.
