Although major economies and markets fared well in 2021 despite all of the uncertainties surrounding new variants of the coronavirus, 2022 will bring new challenges. In addition to central banks shifting toward policy normalization, geopolitical and systemic risks are multiplying.

Despite dips and disruptions from new variants of COVID-19, 2021 turned out to be a relatively positive year for economies and markets in most parts of the world. Growth rose above its potential after the severe recession of 2020, and financial markets recovered robustly. This was especially the case in the United States, where stock markets reached new highs, owing partly to the US Federal Reserve’s ultra-loose monetary policy (though central banks in other advanced economies pursued radically accommodative policies of their own).

But 2022 may be more difficult. The pandemic is not over. Omicron may not be as virulent as previous variants – particularly in highly vaccinated advanced economies – but it is much more contagious, which means that hospitalizations and deaths will remain high. The resulting uncertainty and risk aversion will suppress demand and exacerbate supply-chain bottlenecks.

Together with excess savings, pent-up demand, and loose monetary and fiscal policies, those bottlenecks fueled inflation in 2021. Many of the central bankers who insisted that the inflationary surge was transitory have now conceded that it will persist. With varying degrees of urgency, they are planning to phase out unconventional monetary policies such as quantitative easing, so that they can start to normalize interest rates.

Central banks’ resolve will be tested if policy-rate hikes lead to shocks in the bond, credit, and stock markets. With such a massive build-up of private and public debt, markets may not be able to digest higher borrowing costs. If there is a tantrum, central banks would find themselves in a debt trap and probably would reverse course. That would make an upward shift in inflation expectations likely, with inflation becoming endemic.

The next year also brings mounting geopolitical and systemic risks. On the geopolitical front, there are three major threats to watch.

First, Russia is preparing to invade Ukraine, and it remains to be seen whether negotiations on a new regional security regime can prevent escalation of the threat. Although US President Joe Biden has promised more military aid for Ukraine and threatened harsher sanctions against Russia, he also has made clear that the US will not intervene directly to defend Ukraine against an attack. But the Russian economy has become more resilient to sanctions than it was in the past, so such threats may not dissuade Russian President Vladimir Putin. After all, some Western sanctions – such as a move to block the Nord Stream 2 gas pipeline – could even exacerbate Europe’s own energy shortages.

Second, the Sino-American cold war is getting colder. China increasing its military pressure on Taiwan and in the South China Sea (where many territorial disputes are brewing), and the broader decoupling between the Chinese and US economies, is accelerating. This development will have stagflationary consequences over time.

Third, Iran is now a threshold nuclear state. It has been rapidly enriching uranium to near-weapons grade, and the negotiations over a new or refurbished nuclear agreement have gone nowhere. As a result, Israel is openly considering strikes against Iranian nuclear facilities. Were that to happen, the stagflationary consequences would likely be worse than the oil-related geopolitical shocks of 1973 and 1979.

The new year also brings several systemic concerns. In 2021, heatwaves, fires, droughts, hurricanes, floods, typhoons, and other disasters laid bare the real-world implications of climate change. The COP26 climate summit in Glasgow offered mostly cheap talk, leaving the world on track to suffer a devastating 3° Celsius of warming this century. Droughts are already driving a dangerous spike in food prices, and the effects of climate change will continue to worsen.

Making matters worse, the aggressive push to decarbonize the economy is leading to underinvestment in fossil-fuel capacity before there is a sufficient supply of renewable energy. This dynamic will generate much higher energy prices over time. Moreover, climate refugee flows toward the US, Europe, and other advanced economies will surge just as those countries are shutting their borders.

Against this background, political dysfunction is increasing in both advanced economies and emerging markets. The US midterm elections may offer a preview of the full-blown constitutional crisis – if not outright political violence – that could follow the presidential vote in 2024. The US is experiencing near-unprecedented levels of partisan polarization, gridlock, and radicalization, all of which poses a serious systemic risk.

Populist parties (of both the far right and the far left) are growing stronger around the world, even in regions like Latin America, where populism has a disastrous history. Peru and Chile both elected radical leftist leaders in 2021, Brazil and Colombia may follow suit in 2022, and Argentina and Venezuela will remain on a path to financial ruin. Interest-rate normalization by the Fed and other major central banks could cause financial shocks in these and other fragile emerging markets such as Turkey and Lebanon, not to mention the many developing countries with debt ratios that are already unsustainable.

As 2021 draws to a close, financial markets remain frothy, if not outright bubbly. Public and private equity are both expensive (with above-average price-to-earnings ratios); real-estate prices (both housing and rent) are high in the US and many other economies; and there is still a craze around meme stocks, crypto assets, and SPACs (special purpose acquisition companies). Government bond yields remain ultra-low, and credit spreads – both high-yield and high-grade – have been compressed, owing partly to direct and indirect support from central banks.

As long as central banks were in unconventional policy mode, the party could keep going. But the asset and credit bubbles may deflate in 2022 when policy normalization starts. Moreover, inflation, slower growth, and geopolitical and systemic risks could create the conditions for a market correction in 2022. Come what may, investors are likely to remain on the edge of their seats for most of the year.
