**US Inflation and Interest Rate Expectations:** The elevated US March CPI of 3.3% and a bleaker April outlook could lead the Federal Reserve to maintain or adopt a more hawkish stance on interest rates. This typically impacts the valuation of growth stocks, which are a significant component of the MSCI USA Screened Index tracked by this ETF, by increasing the discount rate for future earnings.

**Geopolitical Stability and Oil Prices:** While Trump's extension of the US-Iran ceasefire has calmed oil markets, the underlying tensions and previous escalations (Iran War Escalation, Hormuz Blockade Drive Oil Volatility) highlight ongoing geopolitical risks. Such instability can cause broad market volatility and dampen investor sentiment towards equities, including those held by SASU, if it signals broader economic disruptions or higher energy costs.

**ESG Investing Trends:** As an 'ESG Screened' ETF, SASU's performance and asset flows are inherently linked to the prevailing trends and investor demand for Environmental, Social, and Governance compliant investments. Continued global emphasis on sustainable investing will likely provide support for this ETF, while any shift away from ESG mandates could pose a headwind.
