TOKYO (Reuters) -Japan’s services sector activity shrank in February at the quickest pace in nearly two years, a survey showed on Thursday, as business took a hit from struggling consumer sentiment after a record spike in infections of the Omicron coronavirus variant.

The activity contraction highlights the challenge Japanese policymakers face in stimulating consumer spending to keep a fragile recovery on track as the Ukraine crisis and supply disruptions worsen uncertainty in the economic outlook.

The final au Jibun Bank Japan Services Purchasing Managers’ Index (PMI) fell to a seasonally adjusted 44.2 from the prior month’s final of 47.6, marking the fastest rate of contraction since May 2020.

While activity stayed well below the 50-mark that separates contraction from expansion on a monthly basis, that was better than a seasonally adjusted 42.7 flash reading.

“Activity and new business declined at the sharpest pace since last August,” said Usamah Bhatti, economist at IHS Markit, which compiles the survey.

Business in the sector saw overall input prices rise for the 15th straight month, citing increased fuel and raw material costs, but that did not lead them to charge more for services as the surge in coronavirus cases hit consumer demand.

“Firms made attempts to stimulate demand by engaging in price discounting measures for the first time in six months, despite a renewed acceleration in average cost burdens,” said Bhatti.

The composite PMI, which is calculated using both manufacturing and services, fell to 45.8 from January’s final of 49.9, contracting at the fastest speed in 18 months.

The world’s third-largest economy is expected to see growth grind to a near halt this quarter, likely growing an annualised 0.4%, as coronavirus curbs and supply bottlenecks weigh on overall activity, a Reuters poll showed this week.
