Big data may help guide Japan economy through pandemic pain

TOKYO: Big data is providing some surprising results for the Bank of Japan and helping ease concerns about pressure on the economy during the coronavirus pandemic, which could influence the way the BoJ manages the world’s most radical monetary stimulus.

By tapping data provided by Google showing people’s movement via mobile phones, the BoJ found that households’ discretionary spending rebounded faster and more vividly in Japan than in other countries after lockdown steps were lifted in May.

Other big data also showed a marked rebound in durable goods sales such as personal computers, which offset some of the weakness in spending on services including leisure, eating-out and travel.

The revelation helped convince BoJ policymakers to conclude the economy has past the worst and did not need immediate, additional monetary support. “We expect the economy to recover gradually and steadily,” BoJ Governor Haruhiko Kuroda said after the bank’s decision this month to keep monetary policy steady.

“Service sectors, such as sports and other events, may not recover to pre-COVID-19 levels easily . . . But consumption and production of goods have hit bottom and are now rebounding sharply,” he said.

Long seen as one of the most conservative central banks when it comes to data, the BoJ is now marshalling a 180-member statistics team to troll through cargo freight movement, traffic data collected from smart phones and satellite images of human activity around factories, for better insights into the economy.

Non-traditional data may also affect the way the BoJ gauges success in meeting its elusive 2 percent inflation target.

An index tracking real-time trends using private data showed prices of some goods rose steadily even as services costs slumped, suggesting price moves may not be as deflationary as the official consumer price index (CPI) suggests.

The findings prompted the BOJ to warn in its quarterly report in July of the need to look at both the inflationary and deflationary impact COVID-19 could have on prices.

While CPI will remain the BoJ’s key price gauge, its policy may become more detached from the index with more alternative information available, some analysts say.

“The BoJ knows its conventional approach of simply tracking CPI won’t work. While they won’t change the 2 percent target, they will start looking at a wider range of data,” said Tsutomu Watanabe, a former BoJ official and a pioneer of big data in Japan.

“Policymakers will have to fully rely on big data. That’s already happening across the world and will only accelerate.”

Major central banks are increasingly turning to real-time data to make quick calls on the pandemic-hit economy, as traditional indicators such as monthly retail sales and unemployment figures arrive too late to give a reliable picture of the impact of COVID-19.

The Federal Reserve has led the drive, tapping numerous high-frequency data and exploring new ways such as creating online polls and an index gauging changes in human movement.

The BoJ is playing catch-up.

Last year, the bank created a task force to better reflect big data findings into its economic projections — a small but significant departure from the 140-year-old institution’s traditional emphasis on theory and models.

It also introduced its version of a weekly index the New York Fed uses that combines frequently updated consumer and industrial activity data into a gauge of gross domestic product.

Kazushige Kamiyama, the BoJ’s top economist who spearheaded the changes, says the bank is ready to hire and develop data scientists who can streamline data collection and analysis. His mission is gaining steam because of the pandemic.

“In times of shock, uncertainty over the state of the economy and its outlook heightens. It’s like driving without your lights on,” Kamiyama said.

“That’s when non-traditional data that gives us quick information, including high-frequency data, become really valuable.”

OPEC raises November oil output by 750,000 bpd

  • Members meet this week to discuss the possibility of cutting oil output

The Organization of the Petroleum Exporting Countries (OPEC) increased oil output for the fifth straight month in November, ahead of the next OPEC + meeting.

OPEC raised oil output by 750,000 barrels per day (bpd) to 25.31 million in November, according to a Reuters survey.

Thus, the oil output continued rising from its 30-year low hit in June.

OPEC had 102 percent compliance with agreement to cut oil supply in November.

OPEC+ members will meet on Monday and Tuesday to discuss the possibility of cutting oil output to 2 million bpd as of January.
