Analysis-Treasury market's next test: rising war costs

Core Viewpoint - Inflation risks and the potential costs of an extended conflict with Iran are driving Treasury yields higher, posing a threat to bond market health [1][2]. Group 1: Economic Impact - Wall Street anticipates a quick resolution to the conflict, which could alleviate pressure on oil prices and government finances, but analysts are calculating the costs of prolonged defense spending and potential economic stimulus [2]. - BNP Paribas forecasts that the U.S. deficit could rise from just below 6% of GDP to around 8% or higher due to added costs from the conflict, which is concerning for bond investors [3]. Group 2: Bond Market Dynamics - The bond market has seen significant selling, particularly in short-term yields, as hopes for near-term Federal Reserve rate cuts diminish, while longer-dated yields have also increased, with the 10-year Treasury nearing 4.5% [4]. - The U.S. fiscal position was already strained before the conflict, with national debt at a record $39 trillion and expected annual net interest payments of $1 trillion [5]. Group 3: Government Revenue Challenges - The Supreme Court's ruling against the president's use of emergency powers to impose tariffs could lead to approximately $175 billion in refunds to importers, impacting government revenue [6]. - The administration plans to impose replacement tariffs, but it remains uncertain if these will fully compensate for the lost revenue [6]. Group 4: Market Sentiment - Currently, markets do not expect significant changes in the U.S. fiscal outlook, with analysts suggesting that they may wait for actual legislation before reacting more decisively [7].
