June 16 (Reuters) – Eurozone bond yields surged on Thursday after an unexpected, big rate hike by Switzerland turned focus to the ramifications of the policy shift for the region, but Italian debt outperformed on ECB efforts to check diverging euro area borrowing costs.

It raised interest rates by 50 basis points in its first increase for 15 years, joining other central banks in tightening monetary policy to fight resurgent inflation. read more

In the bloc’s bond markets, it was a day of big milestones.

Germany’s 10-year yield was up 18 bps to 1.84% by 1322 GMT, the biggest daily jump since March 2020. Five-year yields surged 21 bps, set for the biggest daily jump since 2012.

Yields also rose as money markets ramped up bets on European Central Bank rate hikes to price in around 190 bps of rises by December, compared to 140 bps a day earlier.

“SNB reaction in govvies is the market pricing in an aggressive ECB,” said Arne Petimezas, senior analyst at AFS Group.

The SNB also said recent depreciation meant the Swiss franc was no longer highly valued on currency markets – long a concern for the bank – and a sign that the central bank was ready to loosen its grip on the franc.

The stepping back of the SNB from the currency markets means even lesser euros generated from currency market intervention would flow into eurozone debt, a big factor in keeping yields in check.

Antoine Bouvet, a senior rates strategist at ING noted that the duration of the SNB’s bond holdings are nearly five years, helping explain why five-year German yields rose more than other maturities.

U.S. Treasury yields also rose sharply. The SNB’s U.S. dollar and euro reserve shares are similar, just under 40%. ,

Italian bond yields clawed back much of their earlier rise after a Bloomberg News report, citing unnamed sources, said the ECB’s new anti-fragmentation tool would probably involve selling other securities to avoid upsetting the bank’s efforts to curb record inflation.

The closely-watched spread between German and Italian 10-year yields was last down to 211 bps from around 227 bps earlier and above 250 bps before the ECB’s Wednesday announcement.

Italian 10-year yields reversed an earlier rise and were up 5 bps to 3.96%, from over 4% earlier. Other spreads also tightened. , .

France’s central bank governor had already flagged the possibility of this so-called sterlisation feature. Many analysts expect it to feature in the new tool. read more

The report also briefly sent Germany’s 10-year yield to the highest since 2014 at 1.92% but it quickly came off the day’s highs.
