Italy's Golden Power and Its Implications for Banking Stocks: Navigating Regulatory Risk and Growth Potential in a Post-Privatization Landscape

Italy's banking sector has long been a battleground for regulatory intervention, but in 2025, the “Golden Power” mechanism—formally known as the foreign direct investment (FDI) screening regime—has emerged as a defining force shaping the fortunes of banking stocks. This tool, designed to protect national security and public order, has evolved from a defensive measure against foreign takeovers into a proactive instrument of strategic oversight. For investors, the implications are clear: regulatory risk is no longer a peripheral concern but a central factor in assessing the growth potential of Italian banks.

The Golden Power Conundrum: A Case Study in Regulatory Overreach

The collapse of the UniCredit-Banco BPM merger in July 2025 epitomizes the growing tension between national control and market dynamics. The Italian government invoked Golden Power to impose conditions such as maintaining a 50% loan-to-deposit ratio for five years and exiting Russian operations within nine months. These demands, framed as necessary for “economic security,” were challenged by UniCredit as disproportionate and legally ambiguous. The Regional Administrative Court (TAR) of Lazio partially upheld the bank's claims, yet the government's broader authority to intervene in domestic transactions remains intact.

The fallout was immediate. While UniCredit's shares initially rose 4.6% post-withdrawal due to strong Q2 earnings, the broader market interpreted the collapse as a warning signal. By August 2025, the stock traded at a 12% discount to its 52-week high, reflecting investor unease over regulatory unpredictability. This case underscores a critical risk: when governments weaponize Golden Power to reshape corporate strategies, even well-capitalized banks face existential uncertainty.

The Privatization Paradox: Consolidation in a Regulated Environment

The privatization of public banks in Italy has historically been a path to efficiency, but 2025 reveals a paradox. While BPER Banca's acquisition of Banca Popolare di Sondrio (BPS) at €10.89 per share succeeded, it came with a 5.5% valuation discount and the divestiture of six Lombardy branches. The deal, though approved by the ECB, highlighted lingering skepticism among shareholders.

For BPER Banca, the merger's projected €290 million in cost synergies by 2027 could justify the valuation gap. However, the required branch divestitures and hedging of BPS shares by Unipol SGR suggest that regulatory scrutiny can erode value even in approved transactions. This duality—where consolidation is both a growth driver and a regulatory minefield—defines the post-privatization landscape.

Regulatory Risk as a Market Force

The European Commission's scrutiny of KKR's Telecom Italia acquisition further illustrates the ripple effects of Golden Power. While not a banking deal, the probe into access agreements with rivals Fastweb and Iliad signals a broader regulatory tightening. For Italian banks, this means increased compliance costs and reduced appetite for infrastructure financing—a sector where they often act as intermediaries.

The Italian banking sector's P/E ratio has lagged the EU average since 2023, partly due to regulatory headwinds. The 2024 Annual Report on FDI noted a 47% exclusion rate for Golden Power filings, reflecting the regime's ambiguity. This lack of clarity deters foreign investment and complicates cross-border deals, limiting growth avenues for mid-sized banks.

Investment Strategy: Balancing Risk and Resilience

For investors, the key lies in identifying banks with regulatory resilience. Institutions like BPER Banca, with ECB approval and robust capital ratios, are better positioned to navigate the Golden Power landscape. Conversely, mid-sized banks exposed to unclarified conditions—such as the 50% loan-to-deposit ratio in the UniCredit-BPM case—remain high-risk.

Cost-income ratios are another critical metric. BPER Banca's ratio improved from 55% in 2022 to 48% in 2025, demonstrating operational discipline. In contrast, banks with higher ratios and weaker capital cushions (e.g., Banca Monte dei Paschi di Siena) face greater vulnerability.

The Path Forward: Regulatory Agility as a Competitive Advantage

The Italian government's push for “strategic oversight” is unlikely to abate. However, the UniCredit-BPM case has already triggered a shift in investor behavior. The European Commission's challenge to Golden Power's application in domestic transactions may force regulatory reforms, but until then, agility will be key.

Investors should prioritize banks that:
1. Demonstrate capital efficiency: Look for strong CET1 ratios and disciplined cost management.
2. Diversify revenue streams: Banks with exposure to ESG-aligned sectors or digital transformation are better insulated from regulatory shocks.
3. Engage proactively with regulators: Institutions that align their strategies with national priorities—such as supporting SMEs or green financing—may gain favorable treatment.

Conclusion

Italy's Golden Power regime is a double-edged sword. While it protects strategic assets, it also introduces volatility and uncertainty. For banking stocks, the path to growth lies not in chasing megamergers but in navigating regulatory labyrinths with resilience. As the UniCredit-BPM saga shows, sometimes the most strategic move is to walk away—and focus on what works. In a sector where regulatory risk is inescapable, the winners will be those who turn compliance into competitive advantage.
