Rising Interest Rates ("Higher for Longer"): Preferred stocks, with their fixed dividends, are sensitive to prevailing interest rates. A prolonged period of 'higher for longer' rates can make newer fixed-income offerings more attractive, potentially affecting the market price of existing preferred shares like CMRE-PD.

Geopolitical Tensions and Shipping Lane Disruptions: As a marine shipping company, Costamare Inc. is directly exposed to global trade and the security of shipping lanes. Escalations such as the Iran War and potential Strait of Hormuz closures can lead to increased operating costs (e.g., insurance, fuel) and disruptions in vessel schedules, impacting the company's profitability and its capacity to sustain preferred dividends.

Inflation and Fuel Price Volatility: High US inflation (3.3%) and sustained volatility in oil prices, partly due to events like the Strait of Hormuz closure, directly influence the operational expenses of a shipping company. Elevated fuel costs and general inflationary pressures can compress profit margins, thereby affecting the overall financial health of Costamare Inc., which underpins the preferred stock's dividends.
