FRANKFURT (Reuters) – The European Central Bank raised interest rates again on Thursday and announced it was changing the terms of its ultra-cheap loans to commercial banks in a bid to shrink its bloated balance sheet and fight off a historic surge in inflation.

Worried that rapid price growth is becoming entrenched, the ECB is raising borrowing costs at the fastest pace on record, with further hikes almost certain as unwinding a decade’s worth of stimulus will take it well into next year and beyond.

The central bank for the 19 countries that use the euro raised its deposit rate by a further 75 basis points to 1.5% – the highest rate since 2009. Until as recently as July, ECB rates had been in negative territory for eight years.

The Governing Council took today’s decision, and expects to raise interest rates further, to ensure the timely return of inflation to its 2% medium-term inflation target,” the ECB said in a statement.

The euro dropped and European government bond yields slid after the announcement, which was in line with market expectations.

At a news conference, ECB President Christine Lagarde noted that while the Ukraine war and other global uncertainties meant the euro area economy faced a number of risks to the downside, inflation risks were skewed upwards.

Incoming wage data and recent wage agreements indicate that the growth of wages may be picking up,” she said of the possible emergence of future wage-price spirals, stressing the bank was monitoring expectations about long-term inflation.

Markets expect the pace of the hikes to slow somewhat, with the deposit rate hitting 2% in December, then peaking at around 3% some time in 2023, although the unusually volatile outlook makes this timeline prone to changes.

Asked about concerns expressed by some euro zone governments that the ECB’s rate hikes could throw the region into recession, Lagarde said the ECB had a mandate to fight inflation and urged governments to carefully target any support for citizens through the energy crisis so as not to make inflation worse.

“Everyone has to do their job. Our job is price stability,” she said. “We have to do what we have to do. A central bank has to focus on its mandate.

The ECB offered no hints for now about plans to start winding down its bond holdings, after hoovering up trillions of euros of debt issued by euro zone governments since 2015.

BALANCE SHEET

With euro zone inflation hitting 9.9%, the ECB also took the first step toward shrinking its 8.8 trillion euro balance sheet, a move that is likely to raise borrowing costs further and may act as a sort of disguised rate hike.

In a move which may be fought commercial banks, it curbed the subsidy it provides to such lenders through 2.1 trillion euros worth of ultra-cheap three-year loans called Targeted Longer-Term Refinancing Operations, or TLTROs.

In view of the unexpected and extraordinary rise in inflation, it (TLTRO) needs to be recalibrated to ensure that it is consistent with the broader monetary policy normalisation process and to reinforce the transmission of policy rate increases to bank lending conditions,” the ECB said.

It said the interest rate on TLTRO operations will in future be indexed to the average applicable key ECB interest rates, which will encourage early repayment of the loans.

Making the terms of TLTRO loans to banks more expensive signals a preference to start shrinking this part of the balance sheet more quickly, especially as the cost of paying interest on bank reserves increases,” said Charles Seville, Senior Director, Fitch Ratings.

The ECB said further pricing details would be made available at 1345 GMT. In another change, the ECB also said that minimum reserves would be remunerated at the deposit rate, rather than the main rate, which is 50 basis point higher.

Having borrowed at zero or even negative rates at a time when the ECB’s main worry was persistently low inflation, banks can now simply park TLTRO cash with the ECB and enjoy a risk-free return that rises with each deposit rate hike.

This is politically contentious in itself, but an abundance of liquidity is also keeping money market rates depressed and preventing the ECB’s rate hikes from being fully passed through via the banks to businesses and households.

The biggest chunk of TLTRO loans, worth around 1.5 trillion euros, expire next June. Thursday’s changes may encourage banks to repay them as soon as December, shrinking the ECB’s balance sheet in the process.

The bank confirmed its guidance on reinvestments of bonds maturing in its bond buying schemes, confounding some expectations for a small change that would hint at a wind down of the Asset Purchase Programme next year.
