Geopolitical tensions have recently escalated again. As the United States stepped up its actions in Venezuela, market risk sentiment visibly declined, with substantial capital flowing into safe-haven assets. U.S. Treasury yields declined accordingly, with investors rushing to allocate long-term bonds to lock in returns. Boosted by this, the long-duration bond proxy product TLT showed moderate upward performance, becoming an important tool for risk mitigation. Overall, the decline in yields not only reflects market concerns about geopolitical risks, but also demonstrates investors' strong preference for safe assets.
