Where they climbed in 2 weeks
1Flight-to-Safety Paradox — Why This War Raised Rates Instead of Lowering Them
▸Normally: geopolitical crisis → capital flees to U.S. Treasuries → yields ↓ drop → mortgage rates fall
▸This time: Iran War = oil shock + inflation fears → bond investors demanded higher yields to compensate → rates ↑ rose
▸The war hit during an already-elevated inflation environment — the flight-to-safety effect was overwhelmed by inflation anxiety
2Oil Prices — The Inflation Engine Driving Rates Higher
▸Strait of Hormuz handles ~20% of global oil — any disruption spikes energy prices worldwide
▸Higher oil → higher CPI → Fed stays hawkish → bond yields ↑ up → mortgage rates ↑ up
▸Every $10/barrel rise in oil adds approx. 0.2–0.3% to headline inflation
3The Fed Is Stuck — Caught Between Inflation and Recession Risk
▸Fed can't cut rates while oil-driven inflation is rising — it would look like it's giving up the fight
▸Fed can't raise rates aggressively — war-related economic slowdown could tip into recession
▸Result: Fed paralysis → rates stay elevated longer → no relief for mortgage borrowers in the near term
4War Spending + National Debt = Structural Upward Pressure
▸U.S. military engagement increases deficit spending → Treasury must issue more bonds
▸More bond supply → prices fall → yields ↑ rise → mortgage rates follow
▸This is a structural, multi-year pressure — not a temporary blip
5Bond Weaponization Risk — Adversaries Can Pull the Trigger
▸China holds ~$760B in U.S. Treasuries; Japan holds ~$1.1T
▸A coordinated sell-off by adversary nations would crash bond prices → yields ↑ spike → mortgage rates surge
▸This is a tail risk — low probability but catastrophic if triggered
6Prolonged War Could Damage U.S. Global Standing
▸Extended conflict accelerates de-dollarization — countries seek alternatives to USD for trade settlement
▸Reduced global demand for U.S. Treasuries → yields ↑ structurally higher → permanent mortgage rate pressure
▸Most likely a slow-burn risk over years, not immediate
7MBS Market Volatility — The Direct Link to Your Mortgage Rate
▸Mortgage rates are priced off Mortgage-Backed Securities (MBS), not Fed funds rate directly
▸War uncertainty → MBS investors demand wider spreads (extra yield for uncertainty risk)
▸Even when Treasury yields stabilize, MBS spreads can keep mortgage rates elevated independently
8Ceasefire Effect — Brief Relief, Not a Trend
▸Short-term ceasefires create brief rate dips — American Banker (Apr 2026): rates got "a short-lived reprieve"
▸But structural forces (oil inflation, debt, MBS spreads) don't reverse on a ceasefire announcement
▸Don't wait for ceasefire news to lock. The relief is temporary and unpredictable.
9Historical Precedent — When Geopolitical Crisis Lowers Rates (And When It Doesn't)
✅ RATES FELL (Flight-to-Safety Won)
• Greek Debt Crisis 2011 → ↓ rates down
• Brexit 2016 → ↓ rates down
• COVID 2020 → ↓ 2.65% all-time low
❌ RATES ROSE (Inflation Won)
• Gulf War 1990 → oil spike → ↑ rates up
• Russia-Ukraine 2022 → energy + inflation → ↑ rates up
• Iran War 2026 → same playbook ↑
▸Pattern: when war = inflation shock, rates rise. When war = pure fear, rates fall.
10The Upside Scenario — A Quick U.S. Win
▸A decisive U.S. victory + political stability could reduce risk premium → bond yields ↓ drop → rates could approach high-5s
▸But: oil infrastructure rebuilding, war debt, and Fed credibility lag means relief won't be immediate
▸Don't bank on this scenario. If it happens, refinance. Tiger Loans will help.
11The Verdict — Unpredictability IS the Trend
▸No analyst can predict the outcome of a military conflict with any reliability
▸Unpredictability itself is the reason to act now, not wait
▸The longer you wait, the more scenarios can go against you

How much worse hesitating is
▸Scenario A — Lock at 6.000%, rates later drop to 5.875%: Pay $48.07 extra/month × 7 months = $336.54 max cost. Then refinance.
▸Scenario B — Don't lock, rates spike to 6.25% for 7 months: Miss $353.13 savings/month × 7 months = $2,471.89 cost. No remedy.
