Mortgage Rates Fall to 1-Week Lows as Trump Announces Ceasefire

Q: With the US-Iran ceasefire still fragile, how long can the resulting dip in mortgage rates and oil prices realistically last?

Probably not long unless the ceasefire quickly turns into a verifiable, durable reopening of the Strait of Hormuz. The drop in mortgage rates was a market reaction to lower geopolitical risk, not a change in the underlying inflation picture. Earlier in the day, hotter May CPI data and war-related supply fears were pushing yields higher. Those forces have not disappeared. Mortgage rates track the 10-year Treasury more than the Federal Reserve, so if oil rebounds, inflation stays sticky, or ceasefire doubts grow, lenders can reverse the rate cut within days. That is why the move is best seen as a relief rally, not a new trend. Oil faces the same problem. Prices fell because traders suddenly priced in fewer supply disruptions and a possible reopening of Hormuz, a route that carries roughly a fifth of global oil consumption. But the ceasefire remains disputed, shipping traffic is still not fully normalized, infrastructure damage is real, and Iran has floated tighter control or tolls on transit. Even without renewed fighting, those factors can keep a risk premium in crude. Realistically, the dip can last for days or a few weeks if there are no new attacks and shipping resumes smoothly. For it to last longer, markets would need proof: sustained calm, confirmed passage through Hormuz, no new strikes, and credible progress on sanctions and nuclear issues. Without that, both oil and mortgage rates are likely to stay volatile and could retrace much of today’s move quickly.
