How IB Power & Regulatory Pressure Are Reshaping Banks—While AI Fuels TSMC’s Rise

Here’s how these disparate developments among big banks and TSMC intersect with investment banking strategy and macro risk for Q1 and beyond.

US Banks — Investment Banking Rebound & Regulatory Tension
Q4 2025 has shown strong signs of recovery in the investment banking ecosystem. Leading firms such as Goldman Sachs, Morgan Stanley, JPMorgan, and Citigroup are projected to collect nearly $10 billion in IB fees across these five banks — up about 13% YoY — largely due to rising deal flow, particularly in M&A and underwriting driven by private equity, distressed M&A, and capital markets. ([ft.com](https://www.ft.com/content/f3d79af1-b55a-4c86-b39a-41bf3cec77d1?utm_source=openai)) Meanwhile, regulatory change looms. Senators Warren and Sanders have explicitly urged these banks to reallocate excess capital away from dividends/share buybacks toward lending. ([nasdaq.com](https://www.nasdaq.com/articles/zacks-analyst-blog-highlights-jpmorgan-citigroup-wells-fargo-morgan-stanley?utm_source=openai)) The banks also passed the Fed’s stress tests, signaling balance sheet strength, enabling capital return policies yet simultaneously drawing scrutiny over whether capital is being deployed in ways aligned with public interest.

The strategic implication is banks must balance: maintaining investor-friendly capital distributions; investing back into lending (both consumer and commercial); and managing regulatory expectations, especially if a transition to a more reformist regulatory environment occurs. Banks heavily reliant on IB/trading will benefit most from the current cycle; those more exposed to lending may face either higher returns or liability risks depending on credit conditions.

TSMC — Riding the AI Wave but Navigating Risk
Taiwan Semiconductor Manufacturing Co. (TSMC) is experiencing perhaps its most favorable demand environment in years. Q4 revenue rose by ~20.4% YoY, net profits expected up ~27% YoY, driven particularly by strong utilization at 3-nm nodes, and robust AI accelerated hardware demand. ([reuters.com](https://www.reuters.com/world/china/tsmc-q4-profit-poised-soar-27-ai-demand-drives-growth-2026-01-12/?utm_source=openai)) The 2-nm node is expected to enter production in 2025 with full-scale ramp in 2026, reflecting aggressive technological leadership. ([nasdaq.com](https://www.nasdaq.com/articles/zacks-analyst-blog-highlights-taiwan-semiconductor-manufacturing-nvidia-apple-marvell?utm_source=openai)) However, expanding fabrication capacity abroad (e.g., U.S., Japan, Europe) imposes headwinds: higher capex, geographies with higher input costs and regulatory/export restrictions; plus shrinking skill pools locally as demand for semiconductor engineers outstrips supply.

The strategic takeaway is that while TSMC is likely to outperform many peers for 2025–2026, margins may compress in new fabs, and geopolitical/regulatory risks — especially export control tensions between the US and Taiwan — pose potential downside. Key variables to monitor include cost inflation (labor, energy), export policy shifts (N-2 or similar rules), and talent acquisition.

Intersection & Comparative Strategy
There’s an alignment: secular drivers like AI are fueling both banks (via IB/markets activity) and chipmakers. For investment banks, TSMC-related supply chain financing, IPOs or spin-offs (e.g. in semiconductors) could represent strong deal flow. Simultaneously, TSMC’s capital needs — financing overseas fabs, managing trade risks — may present opportunities for credit or advisory mandates, but also require institutional risk analysis, especially under changing regulatory regimes.

Open Questions & Risks

• Can banking regulators maintain pressure or codify the push toward more lending and limit shareholder distributions without destabilizing capital markets or bank valuations?
• Will TSMC be able to sustain margin trajectories given overseas expansion and increasing export controls?
• What is the risk of broad macroeconomic slowdown (rates, inflation) cutting into IB deal pipelines or AI demand?
• How might U.S.-China policy and export rules reshape both TSMC’s growth path and banks’ exposure to semiconductor sector risks?
