Why the US sinking Iranian boats matters for your mortgage?
Today (4th May) the US Navy destroyed six Iranian boats and intercepted missiles in Hormuz.
Here's the chain reaction that reaches your wallet:
1. Oil prices spike → energy costs rise globally.
2. Higher energy → higher CPI inflation → central banks tighten policy.
3. Tighter policy → higher bond yields → mortgage rates rise.
4. Higher mortgage rates → housing demand falls → construction slows.
5. Slower construction → fewer jobs → consumer spending weakens.
But there's a second channel: confidence.
When a major military engages in naval combat in a shipping lane that carries 20% of global oil, business investment freezes.
Companies delay CAPEX decisions.
Hiring slows.
The "uncertainty tax" is invisible but real - it shows up in lower GDP 6-12 months later.
The Fed held rates at 3.5% - 3.75%. The ECB has paused cuts. BoE has paused. RBA has paused. Markets are now pricing the possibility of hikes if oil keeps rising. All because of energy inflation driven by a war in the Gulf. None of them can fix the problem - they can only distribute the pain.
Higher rates don't produce more oil. They just make it more expensive to borrow while you're paying more for everything else.
Today's naval battle isn't just a military story.
It's the event that locked in higher rates, higher energy costs, and slower growth for the rest of 2026.
The boats are at the bottom of the strait. The ripple effects are just starting.
