Interest rate rises ‘risk a financial earthquake’

Over-tightening by central banks could prompt another crisis, a renowned debt expert tells

- Ambrose Evanspritc­hard

Breakneck monetary tightening by the major central banks is nearing a critical tipping point and risks triggering a chain-reaction of financial distress, the world’s leading expert on debt crises has warned.

“The combinatio­n of recession and rising real interest rates is very dangerous,” says Harvard professor Ken Rogoff, a former chief economist at the Internatio­nal Monetary Fund.

Prof Rogoff is best known for This Time is Different: Eight Centuries of Financial Folly, a magisteria­l history of debt delusions co-written with Carmen Reinhart.

He believes it was a minor miracle that the world averted a financial crisis last year, but the odds of a major accident are shortening as the delayed effects of past tightening feed through.

“We were very fortunate that we didn’t have a global systemic event in 2022, and we can count our blessings for that, but rates are still going higher and the risk keeps rising,” he said on the eve of the World Economic Forum in Davos.

“The risk of over-tightening by the European Central Bank is nothing less than catastroph­ic and they need to be very careful. Italy is extremely vulnerable,” says Prof Rogoff.

“But this could pop anywhere. Global debt has gone up massively since the pandemic: public debt, corporate debt, everything.”

Bursts of optimism over a “softlandin­g” at the end of debt cycles tend to underestim­ate the potency and time-lags of monetary tightening.

The greatest threat lies in the nexus of undisclose­d leverage and liquidity mismatch in the shadow banking sector, which has displaced traditiona­l banking and largely avoided the control of regulators.

These players are not subject to the normal mark-to-market rules forcing them to admit mounting losses. The advance warning signal is muted. Central banks do not know where the landmines lie, or what level of rates will cause the system to buckle.

The giant wild card this time is that serious trouble may also be brewing in Japan’s $12trillion (£9.8trillion) bond market, normally the quietest haven of global finance.

Japan has defied gravity for decades, running nosebleed fiscal deficits for years with no apparent cost or inflationa­ry effect.

But inflation has returned in the aftermath of the Covid-19 pandemic, pushing the country from a bad but stable equilibriu­m into an unstable equilibriu­m. The Bank of Japan is riding a tiger as it tries to manage its exit from extreme quantitati­ve easing and its policy of holding down bond rates .

“The Japanese haven’t had an interest rate rise in three decades and nobody is positioned for it,” Prof Rogoff says.

“The public debt is 260pc of GDP and half of that is overnight debt.”

The dam has already begun to break. The Bank of Japan (BOJ) lifted its long-standing cap on 10-year bonds from 0.25pc to 0.5pc last month, seemingly a minor tweak but in reality a bombshell for internatio­nal capital flows.

The BOJ has had to spend more than $100bn over the past two weeks defending the next line against the market onslaught. The swaps market is already pricing in another jump to 1pc.

A blow-up in the Japanese bond market would be a black swan event. The country is the world’s largest creditor with $3.6trillion of external net assets. It owns 8pc of France’s public debt. A sudden repatriati­on of funds would set off contagion through the internatio­nal system.

Olivier Blanchard, another ex-chief economist at the IMF, has also warned that Japan’s finances are less stable than they look.

He fears that the country could spin into a debt spiral and a funding crisis as it comes out of deflation, leaving the Japanese finance ministry in extreme difficulty.

Prof Rogoff ’s central premise is that global real interest rates “meanrevert” over time. The more suddenly it happens, the greater the financial trauma. The current edifice of internatio­nal borrowing and debt contracts is built on the assumption that real rates will remain nailed to the floor.

In September we had a foretaste of what can happen when UK gilt yields spiked higher, setting off a self-reinforcin­g doom loop in a trillion pound segment of the British pensions industry.

The Bank of England stemmed the crisis with great skill, and made a profit on the bond transactio­ns. However, the episode set off instant global contagion and alarmed officials at the IMF and the Basle-based Financial Stability Board (FSB).

“If it can happen in the UK, which is very well regulated, it can happen anywhere,” Prof Rogoff says.

The liability driven investment­s at the heart of this meltdown were legitimate hedging tools, Prof Rogoff argues, given that pension funds benefit from higher rates. The surprise was the ferocity of the global bond sell-off that set the process in motion.

“Liz Truss got the blame, but the underlying cause was Jay Powell’s rate rises in the US, which has pushed up rates for everybody,” he says.

The eurozone has its own intractabl­e pathologie­s, even if it has weathered Valdimir Putin’s energy war remarkably well. But the delayed effects of monetary tightening are only just starting to bite.

The ECB’S anti-inflation hawks are back in charge and determined to push rates into “restrictiv­e” territory as well as launching bond sales (quantitati­ve tightening), a process likely to continue until something breaks.

“The glue that has been holding the eurozone together is the world of zero real interest rates,” Prof Rogoff says. “So long they stayed at zero you could use QE as a transfer subsidy from the north to the south, and it didn’t seem to cost anything. The underlying problem was never resolved.”

The ECB’S bond purchases have been soaking up Italian debt issuance since 2015, shielding the country from market forces. This stopped in June. The ECB cushioned the blow for a few months by skewing the rollover of its existing portfolio from German Bunds to Italian bonds, but this too has reached its limits.

Markets doubt whether a new “anti-spread” tool (TPI) can be activated in any circumstan­ces short of an emergency. To do so earlier would breach the no-bail clause in the EU treaty law and look all too like fiscal dominance, leading to legal challenges.

But Italy is at least a “knownknown”, and the Meloni government has so far been careful not to provoke trouble.

The global shadow banking system is a “known-unknown”, with a pervasive mismatch in maturities. Many borrow on the short-term capital markets to lend long or invest in illiquid assets – more or less the story of Northern Rock or Lehman Brothers before the global financial crisis.

Unlike normal banks, they cannot borrow from the emergency lending window of central banks, and they lack a stable base of savers covered by deposit insurance.

Prof Rogoff says private equity groups have borrowed heavily to play property markets, which are in various degrees of distress.

Prices in the $21trillion market for American commercial property have dropped 13pc from their peak. Average American house prices are falling at a faster pace than during the sub-prime crisis, though they have not yet fallen nearly as far.

“I think the property market still has a long way to fall. Some of those private equity firms are going to go bust,” he says.

The FSB says the “non-bank” shadow sector today accounts for half of the total $487trillio­n of financial assets worldwide. It warns that over $50trillion of this is “susceptibl­e to runs” if liquidity dries up or there is an external shock.

To borrow Warren Buffett’s famous adage, you only discover who is swimming naked when the tide goes out.
