Global credit markets face mounting exposure to artificial intelligence spending as rating agency Fitch warns that soaring tech valuations mirror the late-1990s dotcom boom. Simultaneously, Fitch maintained Poland’s credit rating at A- with a negative outlook, citing high fiscal deficits and political friction over state spending.
AI Spending Surge and Credit Market Vulnerabilities
The rapid expansion of artificial intelligence infrastructure is creating significant new risks for global financial stability. According to the ratings agency Fitch, unprecedented corporate spending on AI has become deeply intertwined with broader capital markets and economic growth, particularly in the United States. This connection leaves the wider economy vulnerable to any potential market correction.
Valuations across the technology sector have climbed sharply. The cyclically adjusted price-to-earnings ratio for the U.S. S&P 500 has risen to levels close to those observed during the dotcom boom of the late 1990s. At the same time, corporate bond issuance in the United States surged during the first half of 2026, driven largely by fundraising related to artificial intelligence initiatives.
Major technology corporations are driving an extraordinary wave of capital expenditure. Amazon, Alphabet, and Nvidia are among those involved.
Uncertainty over future AI revenues, labor market disruption, and intensifying competition could trigger a prolonged market correction with widespread macroeconomic consequences.
Poland Retains A- Credit Rating Amid Fiscal Concerns
While global credit analysts examine tech sector valuations, sovereign debt watchers are closely tracking fiscal developments in Central Europe. American credit agency Fitch decided to maintain Poland’s long- and short-term foreign and local currency ratings at A-/F1. The decision matched expectations from financial analysts at institutions like PKO BP, ING, and mBank.
The agency stated that the rating is supported by a large, diversified, and resilient economy, benefits stemming from European Union membership, reliable monetary and exchange rate policies, and a solid external financial position relative to peer countries. Poland has maintained this A- rating status since 2007.
However, the agency kept Poland’s rating outlook at negative. This negative trajectory reflects high budget deficits, rapidly climbing public debt, and lower governance indicators compared to similarly rated nations. Fitch pointed to the absence of a credible fiscal consolidation plan and ongoing domestic political challenges as central concerns that weaken confidence in the government’s ability to curb deficits.
Government Tax Reforms and Fiscal Projections
The credit rating evaluation arrives as Donald Tusk and Finance Minister Andrzej Domański advance a major package of tax reforms. The planned adjustments alter personal and corporate income taxes across several brackets.
Under the proposed overhaul, the personal income tax (PIT) threshold rises from 120 tys. zł to 130 tys. zł. A new 24-proc. PIT rate applies to earners making between 130 tys. zł and 150 tys. zł, leaving the top 32 proc. rate restricted to earnings above 150 tys. zł.
Government officials maintain that lower PIT revenue will be balanced by the higher CIT rate, making the reform neutral for the state budget without generating pressure on public finances. Fitch projects that Poland’s budget deficit will reach 6.7 proc. PKB, exceeding the agency’s earlier forecast of 6.2 proc.. Furthermore, the agency expects the broader general government gross debt to climb from 59.7 proc. in 2025 to 72.7 proc. by 2028.
Political Friction and Geopolitical Pressures
Domestic political friction continues to complicate economic policymaking in Warsaw. Fitch highlighted that a high volume of presidential vetoes restricts the government’s ability to implement effective economic measures and compensation strategies. Finance Minister Andrzej Domański acknowledged these institutional hurdles, noting that the agency correctly identified how political conflict constrains policy execution.
Broader international factors are also compounding credit risks worldwide. Fitch warned that geopolitical conflicts, including the U.S.-Iran conflict alongside disruptions in the Strait of Hormuz, are threatening global stability.
Adding to these macroeconomic headwinds, a strong El Niño weather pattern introduces additional pressures on junk-rated countries.
