Global Market: Euro zone bond yields dip ahead of US CPI, heavy debt supply

Euro zone government bond prices edged higher on Wednesday as investors remained cautious ahead of potentially market-moving U.S. inflation data, while a heavy pipeline of new bond supply from Germany and the United States also kept trading activity subdued, Reuters reported.

Renewed concerns over the Middle East added another layer of uncertainty to bond markets after fresh attacks on shipping in the Gulf pushed oil prices above $89 a barrel. The rise in crude prices has raised fears that the conflict could prolong inflationary pressures globally, a development that would be particularly damaging for fixed-income assets.

German bund yields ease

Benchmark 10-year German Bund yields fell by around 2 basis points to 3.163%, though they remained on track for an increase of about 3 basis points for the week. Two-year Schatz yields, which are more sensitive to changes in inflation and monetary policy expectations, were broadly unchanged at 2.785%.


Most major government bond markets had recorded price gains at the start of August, sending yields lower as hopes of a potential Middle East peace agreement pushed oil prices down during the first week of the month.

However, those gains have since been partly reversed as renewed attacks and the absence of an agreement over shipping conditions through the Strait of Hormuz have weakened expectations of a quick resolution to the conflict. The key maritime route remains crucial for global energy supplies, keeping oil and inflation concerns elevated.

U.S. CPI data in focus

Reuters reported that the U.S. Consumer Price Index data for July, due later on Wednesday, could play a major role in shaping expectations for the Federal Reserve's September policy decision.

Money markets currently indicate roughly even odds of a U.S. rate increase, meaning an unexpected inflation reading could trigger significant moves in U.S. Treasuries and spill over into bond markets worldwide.

Market-based measures of expected euro zone inflation one year ahead were trading around 2.4%, above the European Central Bank's 2% target. These expectations had fallen below the target in early July before geopolitical tensions resurfaced, though they remain well below the levels of around 3.8% seen in June.

By comparison, U.S. inflation swaps remained below 2%, suggesting investors are less concerned about persistent inflationary pressures in the world's largest economy. The United States' position as a net oil exporter has helped limit some of its exposure to rising global crude prices.

Heavy bond supply ahead

Investors were also preparing for a sizeable round of government bond issuance on Wednesday.

Germany is set to sell around 2.5 billion euros worth of bonds maturing in 2038 and 2053. The auctions follow strong demand for 4.6 billion euros of five-year Bobls sold on Tuesday at an average yield of 2.93%, the highest auction yield for that maturity so far this year and significantly above the 2.32% recorded a year earlier.

Reuters reported that Commerzbank expects the longer-dated German issuance to potentially create temporary pressure on bond markets, although the bank believes demand should be sufficient to absorb the supply, following the strong reception for Tuesday's auction.

Meanwhile, the U.S. Treasury is scheduled to sell $42 billion of new benchmark 10-year notes, adding to the supply pressure facing global bond markets.

With oil prices, geopolitical developments, U.S. inflation data and a substantial supply calendar all competing for investor attention, bond markets are likely to remain sensitive to fresh signals on inflation and the future direction of interest rates.
