Your mind (Mercury) is naturally drawn to matters of wealth, value, and security, but with Pluto in the mix, this becomes intensified. You likely have a sharp, investigative mind regarding financial opportunities, and you might possess an almost instinctive ability to detect hidden trends in money matters.
You may prefer to keep your financial dealings private, and you likely have a long-term strategy when it comes to wealth-building. You might not share details about your earnings, investments, or plans with others.
Pluto brings a need for control, and in the second house, this translates into a deep psychological need to control money, resources, and stability. At times, this could lead to extremes - either hoarding wealth out of fear of losing it or taking significant financial risks in pursuit of power.
Pluto in the second house often brings periods of financial upheaval that force transformation somehow. You may experience phases of financial loss and gain that lead to a complete restructuring of your values and approach to money.
Your Sun in Sagittarius adds a different tone to the financial picture and may serve as a counterbalance. This could indicate a push-pull dynamic between wanting financial security (Pluto-Mercury) and wanting to take risks or spend money on travel, education, or philosophical pursuits (Sagittarius Sun).
