EU Proposes New Capital Gains Tax Harmonisation: Winners and Losers Across Member States

The euro took center stage on Thursday, sliding to fresh multi-month lows after the European Parliament accelerated debate on a sweeping wealth tax proposal. The move rattled currency markets and prompted a sharp reaction from international investors, who are weighing the potential impact of the legislation on capital flows and cross-border investment. ## Market Overview The **EUR/USD** pair dropped **0.7%** to **1.0410**, marking its lowest close since early March. The broader **U.S. Dollar Index (DXY)** climbed **0.5%** to **106.8**, as traders rotated into the greenback on safe-haven demand. European equities also felt the pressure. The **Stoxx Europe 600** slipped **0.4%**, underperforming U.S. benchmarks, as financials and luxury stocks led losses. U.S. markets held up better: the **S&P 500** edged down **0.1%** to **5,020**, while the **Nasdaq Composite** finished flat at **15,890**. The **Dow Jones Industrial Average** managed a modest gain, rising **0.2%** to **39,300**. Bond markets reflected the growing uncertainty. The yield on the benchmark **10-year German bund** rose **6 basis points** to **2.71%**, while the **U.S. 10-year Treasury yield** ticked up to **4.46%** as investors recalibrated expectations for European growth and policy risk. In commodities, **Brent crude** settled at **$85.10 per barrel**, up **1.3%** on renewed concerns over Middle East supply. **Spot gold** held steady at **$2,330 an ounce**, showing little reaction to the currency moves. ## Key Movers The euro’s decline was the day’s dominant theme, with currency desks citing the EU Parliament’s decision to fast-track debate on a new wealth tax bill as a major catalyst. The proposed tax, which would target high-net-worth individuals across member states, has stoked fears of capital flight and reduced appetite for euro-denominated assets.
