The phrase "in debt like Greece" is currently applicable to numerous nations worldwide, as global debt levels escalate to unprecedented heights.

By the end of this year, public debt across the globe is anticipated to surge by $12.3 trillion, reaching a total of $77 trillion, according to projections by S&P Global Ratings.

In relation to the global GDP, which the International Monetary Fund estimates will exceed $110 trillion in 2024, the sovereign debt ratio is expected to stand at approximately 70%.

Moreover, the global debt accumulation is outpacing GDP growth.

In the last decade, the world GDP has risen by 46%, while sovereign debt has increased by 67.7%.

Total global debt, encompassing both sovereign and private debt, soared by 50% during the same period, bringing the current global indebtedness to $318.4 trillion, approximately three times the world GDP. This alarming trend has led experts to express concerns about the potential for a financial crisis that could surpass the severity of the one experienced in 2008.

The growth of public debt has outstripped that of other debt categories, such as household or corporate debt, for several reasons.

Key drivers include increased borrowing during the COVID-19 pandemic to support economies and citizens, rising defense expenditures spurred by the ongoing conflict in Ukraine, and higher public spending in major economies, compounded by elevated interest rates that have further burdened debt levels.

High levels of debt often incite anxiety as they can easily precipitate financial crises, adversely affecting economic activity.

Typically, it is not the heavily indebted nations that suffer the most; rather, it is often less-developed countries that find themselves in dire straits, frequently encumbered by unfavorable loans and facing significant challenges in repaying borrowed funds.

As a smaller and still developing nation, Serbia may find itself facing similar issues, while remaining largely powerless to influence the rules set by major global players.

Financial crises arising from over-indebtedness can also trigger a myriad of related problems, including diminished investment activity and plant closures.

Such scenarios present nightmares for any governing body, as they typically result in layoffs or, at best, reductions in employee wages.

Robert Sifon Arevalo, head of the ratings department at S&P Global Ratings, notes that major economies continue to employ fiscal policies to address crises, leading to increasing debts for these states.

He further comments on the substantial rise in debt servicing costs, as bond yields have surged since central banks concluded their government bond purchasing programs.

Borrowing to finance increased spending was sustainable when interest rates were low, but has now become problematic.

Billionaire Ray Dalio has warned that many large countries are endangered by excessively high sovereign debt levels.

For instance, he points out that the United Kingdom risks entering a debt spiral, necessitating continuous borrowing to service current obligations, potentially triggering a cascade of government bond sell-offs.

In the United States, significant budget deficits, enormous interest expenses, and large amounts earmarked for refinancing existing debt elevate long-term bond issuance to $4.9 trillion for the current year.

This figure does not account for short-term Treasury bills or various forms of public debt, such as those owed by local authorities.

The fiscal deficit in the U.S. is projected to remain above 6% of GDP through 2026. The status of the U.S. dollar as a global reserve currency continues to provide the country with a degree of flexibility in managing its public finances.

In China, the issuance of long-term bonds is set to increase by over $370 billion, totaling $2.1 trillion, in an effort to bolster domestic consumption and revive the national economy.

Excluding G7 countries and China, public borrowing in the rest of the world is expected to remain largely unchanged from the previous year, according to S&P Global Ratings.

The total global public debt as a percentage of GDP is projected to increase to 70%, a rise compared to 2022, but still shy of the record 73.8% recorded in 2020 when nations globally enacted substantial stimulus packages during the pandemic.

Milojko Arsić, a professor at the Faculty of Economics in Belgrade, describes the increase in global public debt as a troubling trend with potentially adverse effects on developing countries.

He emphasizes that monetary and fiscal policies adopted to confront challenges posed by the COVID-19 pandemic have significantly elevated public debt.

While the world's most economically advanced nations carry the most debt, they also face the lowest servicing costs, contrasting with developing nations that are heavily indebted and subject to high interest rates.

Arsić posits that these countries would be the most adversely affected in the event of a global financial crisis, as they could experience substantial budget deficits impacting their economic activities.

Furthermore, Arsić notes that developments on the global stage directly affect Serbia.

Should a financial crisis impact its largest economic partners, the repercussions would likely reverberate throughout the Serbian economy.

He warns that a scenario where the fiscal deficit surpasses planned levels could lead to significant difficulties, although he expresses optimism that Serbia's main partners will not face insurmountable public debt crises and anticipates that Serbia will maintain its fiscal discipline in partnership with experts from the International Monetary Fund.

Another professor from the Faculty of Economics in Belgrade, Ljubodrag Savić, reinforces that the rise in global public debt has become a reality.

He highlights the increasing financial commitment to military spending in many governments' budgets, particularly within the European Union, which has felt compelled to increase defense spending amid fluctuating assurances from the United States under different administrations.

While rising investments in military capabilities may benefit certain sectors, they also represent broader socioeconomic challenges, particularly regarding poverty alleviation and social projects that, regrettably, remain underprioritized.

Savić reiterates that Azerbaijan’s economic reliance on the EU means that any financial distress within the bloc will inevitably impact Serbia, potentially leading companies with ties to European markets to reduce production, thereby threatening jobs within Serbia while maintaining stability in their home nations.

This could also result in diminished direct foreign investments, posing further challenges for the domestic economy.
