The Power of Partnerships

By partnering with experienced individuals across wealth disciplines, Morgan Stanley Financial Advisors can align specialized resources with your custom needs and deliver strategic guidance through the familiarity and trust of existing relationships
Morgan Stanley Wealth Management Financial Advisers can conduct their business in several ways: individually, as a member of a team of Financial Advisors, or through the formation of a Strategic Partnership with another Financial Advisor or team of Financial Advisors. A Strategic Partnership is an arrangement between a Financial Advisor or a team of Financial Advisors with another Financial Advisor or team of Financial Advisors that has a unique focus or knowledge regarding a specific business concentration, product area, and/or client type. If your account is with an individual Financial Advisor, that Financial Advisor services all facets of your account. If your account is with a Financial Advisor who is a member of a team, any Financial Advisor on the team can service your account. If your Financial Advisor is part of a Strategic Partnership, his or her role in that Strategic Partnership may be limited to a specific business and/or product area and may not cover all facets of your account. The use of the terms “Partner” or “Strategic Partner” and/or “Partnership” or “Strategic Partnership” are used as terms of art and not used to imply or connote any legal relationship.

2025 Global Economic Outlook: U.S. Policies May Temper Global Growth

Global growth is likely to be around 3% in 2025 and 2026, as tariff and immigration policies begin to slow the U.S. economy late next year, and China's underperformance restrains emerging markets.
