The world’s central bank umbrella body, the Bank for International Settlements (BIS), called on Sunday (Jun 25) for more interest rate hikes, warning that the world economy is now at a crucial point as countries struggle to rein in inflation.

Despite the relentless rise in rates over the last 18 months, inflation in many top economies remains stubbornly high, while the jump in borrowing costs triggered the most serious banking collapses since the financial crisis 15 years ago.

“The global economy is at a critical juncture. Stern challenges must be addressed,” Agustin Carstens, BIS general manager, said in the organisation’s annual report published on Sunday. “The time to obsessively pursue short-term growth is past. Monetary policy must now restore price stability. Fiscal policy must consolidate.”

Claudio Borio, the head of BIS’ monetary and economics unit, added there was a risk that an “inflationary psychology” was now setting in, although the recent bigger-than-expected rate hikes in Britain and Norway showed that central banks were pushing “to get the job done” in terms of tackling the problem.

Their challenges are unique by post-World War II standards though. It is the first time that, across much of the world, a surge in inflation has co-existed with widespread financial vulnerabilities.

The longer inflation remains elevated, the stronger and prolonged the required policy tightening, the BIS report said. It warned that the possibility of further problems in the banking sector was now “material”.

If interest rates get to mid-1990s levels, the overall debt service burden for top economies would – all else being equal – be the highest in history, Borio said. “I think central banks will get inflation under control. That is their job – to restore price stability,” he said. “The question is what will the cost be.”

The Swiss-based BIS held its annual meeting in recent days, where top central bankers discussed the turbulent last few months.

March and April saw a failure of a number of US regional banks including Silicon Valley Bank and then the emergency rescue of Credit Suisse in the BIS’ own backyard.

Historically, about 15 per cent of rate hike cycles trigger severe stress in the banking system, the BIS report showed, although the frequency rises considerably if interest rates are going up, inflation is surging or house prices have been rising sharply.

It can even be as high as 40 per cent if the private debt to gross domestic product (GDP) ratio is in the top quartile of the historical distribution at the time of the first rate hike.

“Very high debt levels, a remarkable global inflation surge, and the strong pandemic-era increase in house prices check all these boxes,” the BIS said.

It estimated too that the cost of supporting ageing populations will grow by approximately 4 per cent and 5 per cent of GDP in advanced (AEs) and emerging market economies (EMEs) respectively over the next 20 years.

The absence of belt-tightening by governments would push debt above 200 per cent and 150 per cent of GDP by 2050 in AEs and EMEs; and could be even higher if economic growth rates wane.

Part of the report published already also laid out a “game changing” blueprint for an evolved financial system where central bank digital currencies and tokenised banking assets speed up and smarten up transactions and global trade.

Commenting further on the economic picture, Carstens, former head of Mexico’s central bank, said the emphasis was now on policymakers to act. “Unrealistic expectations that have emerged since the Great Financial Crisis and Covid-19 pandemic about the degree and persistence of monetary and fiscal support need to be corrected,” he said.

The BIS thinks an economic “soft, or soft-ish” landing – where rates rise without triggering recessions or major banking crashes – is still possible, but accepts it is a difficult situation.

Analysts at Bank of America have calculated there have been a whopping 470 interest rate rises globally over the past two years compared with 1,202 cuts since the financial crash. The US Federal Reserve has lifted its rates 500 basis points (bps) from near zero, the European Central Bank has hiked the eurozone’s by 400 bps, and many developing world economies have done far more.

The question remains what more will be needed – especially with signs that companies are taking the opportunity to boost profits, and workers are now demanding higher wages to prevent a further erosion of their living standards. “The easy gains have now been reaped, and the last mile is going to be more difficult,” Borio said, referring to challenges central bankers now face in reeling inflation back to safe levels. “I wouldn’t be surprised if there were more surprises.” Reuters
