Billionaire businessman and former New York City Mayor Michael Bloomberg is warning that governments around the world are running out of time to address soaring public debt, arguing that today’s fiscal challenges are becoming one of the greatest long-term risks facing the global economy.

In an opinion article published Thursday, July 9, Bloomberg said advanced economies have allowed government borrowing to climb to levels not seen since the aftermath of World War II, leaving fewer options to respond to future financial crises.

His central argument is that governments rescued the private sector during the 2008 financial crisis and again during the COVID-19 pandemic, but may no longer have the financial capacity to provide similar support if another major economic shock occurs.

“The next crisis could be different,” Bloomberg argued, warning that governments themselves have become increasingly overleveraged.

According to Bloomberg, government debt across advanced economies has risen from roughly 70% of gross domestic product in 2007 to approximately 110% of GDP in 2025, driven by years of deficit spending that accelerated during the pandemic.

Higher interest rates have made the situation even more challenging by increasing the cost of servicing that debt.

The concerns extend well beyond a single country.

Many developed economies continue running substantial annual deficits despite relatively strong labor markets and economic growth, reducing their financial flexibility before the next recession arrives.

Bloomberg argues that delaying difficult fiscal decisions only makes future adjustments more painful.

He called for governments to gradually reduce spending growth, improve tax collections where appropriate and strengthen financial safeguards while economic conditions remain relatively stable rather than waiting until markets force more dramatic action.

His warning echoes concerns raised by several independent fiscal organizations.

The Congressional Budget Office projects that U.S. federal debt will continue climbing over the coming decades if current spending and revenue policies remain unchanged.

Some bipartisan lawmakers have proposed limiting annual budget deficits to approximately 3% of GDP, arguing that such a target could stabilize the nation’s long-term debt burden.

Economists generally agree that sustained increases in government borrowing eventually place upward pressure on interest rates as governments compete with businesses and consumers for available capital.

Higher borrowing costs can affect nearly every part of the economy, including mortgage rates, corporate financing, consumer loans and business investment.

For companies, persistent government borrowing may also reduce access to private capital as investors allocate more money toward government debt securities.

Bloomberg acknowledged that addressing large budget deficits is politically difficult because it often requires either reducing government spending, increasing taxes or some combination of both.

Those choices have historically proven unpopular regardless of which political party controls government.

Nevertheless, he argued that acting sooner allows policymakers to make gradual adjustments rather than being forced into severe spending cuts or tax increases during an economic emergency.

Financial markets have increasingly focused on long-term fiscal sustainability as government borrowing continues expanding across many developed nations.

Investors closely monitor debt levels because they influence inflation expectations, interest rates, currency values and sovereign credit ratings.

Bloomberg’s warning also comes as governments worldwide continue making significant investments in artificial intelligence, infrastructure, defense, energy security and industrial policy, increasing pressure on already strained public finances.

Although he stopped short of predicting an imminent debt crisis, Bloomberg argued that governments should use today’s relatively stable economic conditions to strengthen their fiscal positions before another major downturn arrives.

For businesses, the message is straightforward: government debt is no longer simply a public policy issue. Rising deficits increasingly influence borrowing costs, investment decisions, financial markets and long-term economic growth.

Bloomberg concluded that the opportunity for gradual reform remains available—but that window is steadily narrowing.
