​Over the past two weeks, the US–Iran conflict has shifted from a tentative stabilisation phase back into renewed escalation, reinforcing the fragility of any diplomatic progress. Following initial attempts to de-escalate through a temporary ceasefire and negotiations, the situation deteriorated quickly as violations emerged and trust between both sides eroded. Diplomatic talks ultimately failed, leading to a resumption of military activity centred around the Strait of Hormuz, including targeted strikes and increased naval presence. Most notably, the conflict has moved beyond isolated engagements towards a broader strategic confrontation, with measures aimed at disrupting Iran’s economic and energy infrastructure, significantly raising the risk of prolonged instability and further escalation across the region. 

​At the end of last week, the US Supreme Court delivered a major legal rebuke to executive trade policy, ruling that President Trump exceeded his authority by imposing sweeping global tariffs under the International Emergency Economic Powers Act (IEEPA). The Supreme Court finds that the statute did not authorize broad tariff powers and therefore invalidating large portions of his tariff regime. In response, President Trump immediately pivoted to alternative statutory authorities, including a temporary global tariff of 10% - later increased to 15 % - under Section 122 of the 1974 Trade Act. This announcement signals further industry- and country-specific tariffs under national-security provisions, keeping trade policy uncertainty elevated. The legal clash and policy recalibration have fed deep political polarization over trade and economic strategy. Consequently, public polling shows substantial opposition to the tariff agenda and debate within both parties over statutory authority, executive power and economic priorities. These issues contribute to amplifying uncertainty in business confidence and strategic investment planning. These political dynamics intersect with broader economic signals that have diverged across the US economy. Manufacturing data show pockets of strength while consumer and business confidence remain subdued, and labour-market resilience coexists with weakness in investment and real incomes, underscoring the uneven impact of policy shifts and structural pressures on growth. Against this backdrop, market participants have increasingly adopted the “Sell America” narrative, a term describing sustained selling pressure on USD-linked assets amid perceived policy risk, with reallocation toward foreign equities, FX and alternative stores of value. The later is further boosted by geopolitical uncertainty.

Japan moved into focus following the high-stakes re-election of the lower house – a vote that was seen as politically risky but ultimately stabilising. Pre-election uncertainty had raised concerns about fiscal discipline and the policy coordination with the Bank of Japan, triggering short-term volatility in both equities and the yen. However, the successful re-election delivered continuity, preserving the reform agenda centred on corporate governance improvements, shareholder returns and gradual structural adjustments. For foreign investors, the outcome reduced near-term political tail risk while maintaining policy predictability. With political clarity restored, focus is shifting back to earnings momentum, currency stability and valuation support, bringing renewed attention to the trajectory of the Nikkei 225 and broader global equities.
Equity markets experienced a sharp but ultimately contained bout of volatility over the past two weeks, driven primarily by earnings dispersion rather than a deterioration in the broader macro backdrop. The correction was most acute within high-multiple software names, where listed SaaS companies declined by 32% from recent highs, as shown in Figure 1. While weaker forward guidance, elongating enterprise sales cycles and moderating net revenue retention were important catalysts, a deeper structural concern also emerged. Advances in generative AI may render parts of the traditional SaaS stack partially obsolete. Investors increasingly question whether AI-native platforms – capable of automating workflows end-to-end – could compress pricing power, reduce seat-based revenue models, or disintermediate legacy application-layer providers altogether.

​Throughout 2025, the US macroeconomic environment was characterised by a gradual normalisation following the post-inflation shock period of prior years. Inflation was largely brought under control, consistently hovering in a narrow 2-3% range - still above the Federal Reserve’s formal 2% target, but sufficiently contained to reduce its dominance in policy deliberations. As price pressures stabilised, the Fed progressively shifted its focus towards labour-market dynamics, with unemployment emerging as the marginal variable guiding monetary policy decisions. During the first half of the year, policymakers remained deliberately cautious, refraining from early rate cuts amid concerns that premature easing could reignite inflation, particularly given still-historically strong employment conditions, even as unemployment began to trend higher. This stance changed in the autumn and winter months, when a clearer softening in labour markets, combined with inflation remaining at tolerable levels, provided the Fed with sufficient confidence to pivot. Over this period, the central bank implemented three 25 basis-point rate cuts, signalling a controlled transition towards a more accommodative stance while maintaining credibility on inflation containment.
