Markets closed, Portugal issues debt as US inflation data looms

The markets are closed on Monday, but the week ahead will demand attention. Investors are waiting for Tuesday to begin processing what has happened in the Middle East—a conflict that has already reshaped the calculus of global finance. The closure of the Strait of Hormuz has sent oil prices climbing, and that pressure is moving through the system in ways both visible and not yet fully understood.

When the European purchasing managers' index came in for March, it told a story of an economy grinding toward a halt. The Eurozone was nearly stagnant, held back by one force above all others: the cost of making things. Petroleum prices, spiking because of the Middle East disruption, have become the principal weight on production. On Tuesday, S&P Global will release the final numbers and break them down by country—Germany, France, Spain, Italy—so analysts can see which economies are feeling the pressure most acutely.

Portugal is returning to the debt markets this week, looking to raise between 1.25 and 1.5 billion euros through ten-year and fourteen-year bonds. The yield on Portuguese ten-year debt is hovering near 3.5 percent, pushed higher by the same forces unsettling everything else. Portugal is not alone. Germany and the United States are also issuing sovereign debt at the ten-year maturity, and the spreads between them will tell investors something important: how much extra return they now demand to hold Western government bonds. The risk premium is rising.

Monetary policy is the question everyone is asking. The Federal Reserve left interest rates unchanged at its last meeting and offered little clarity about what comes next. Jerome Powell said only that the Middle East conflict carried "uncertain" implications. The minutes from that meeting, due out this week, will contain more detail about what the committee actually discussed, what they fear, what they're watching. Those minutes matter because they shape expectations about whether the Fed will cut rates, hold steady, or tighten further.

By week's end, the economic picture should come into sharper focus. Germany will report trade data that may already show shifts in commerce with its major partners. The United States will release final GDP figures for the fourth quarter of 2025—the last full quarter before the war began. Growth came in at 0.7 percent, the slowest pace since the economy contracted in the first quarter of that year. That number becomes a baseline: it shows how much momentum the world's largest economy had before the disruption.

The week closes with American inflation data for March, the first full month of conflict. These numbers will show whether rising oil prices have begun to work their way into what consumers actually pay. Analysts expect the monthly increase to approach 1 percent, with the year-over-year rate climbing to around 3 percent. That figure will be scrutinized for clues about the Fed's next move—and for something larger: whether this temporary shock to the system will harden into something structural, a permanent shift in how the global economy functions. The answer is not yet clear.
