Asia FX: Understanding the Impact of US-Iran Tensions on Currencies (2026)

The Perfect Storm Brewing for Asian Currencies: Beyond the Headlines

There’s a quiet crisis unfolding in the currency markets, and it’s one that could have far-reaching implications for Asia’s economic landscape. While headlines often focus on the big players like the USD or EUR, the recent pressure on the Indonesian Rupiah (IDR), Philippine Peso (PHP), and Indian Rupee (INR) is a story that deserves more attention. Personally, I think what makes this particularly fascinating is how it’s not just about currency fluctuations—it’s a convergence of geopolitical tensions, domestic vulnerabilities, and global economic forces.

The Geopolitical Elephant in the Room

One thing that immediately stands out is the role of geopolitical risks, especially the US–Iran standoff. Lloyd Chan from MUFG rightly points out that a de-escalation, particularly an agreement securing the Strait of Hormuz, could ease the pressure on these currencies. But here’s the kicker: what many people don’t realize is that this isn’t just about oil prices or shipping lanes. It’s about the broader uncertainty that ripples through emerging markets, making investors skittish and driving them toward safer assets like the USD.

If you take a step back and think about it, this raises a deeper question: how much control do these economies really have over their own destinies when global geopolitics can so easily upend them? It’s a sobering thought, especially for countries like Indonesia, the Philippines, and India, which are already grappling with domestic challenges.

Indonesia’s Double-Edged Sword

Let’s talk about the IDR. On paper, it looks cheap on a REER basis, and higher-yielding SRBI instruments offer some compensation for the risk. But here’s where it gets interesting: the rupiah’s vulnerability isn’t just about external pressures. Rising fiscal and current account deficits, coupled with weak investor sentiment around government policies, are creating a perfect storm.

What this really suggests is that Indonesia’s currency woes are as much about internal weaknesses as they are about external shocks. From my perspective, this is a classic case of a country caught between a rock and a hard place. While a breakthrough in US–Iran negotiations could provide temporary relief, the underlying issues—like fiscal mismanagement and policy uncertainty—aren’t going away anytime soon.

The Philippines: Inflation and Policy Missteps

Now, let’s shift to the PHP. What makes this particularly concerning is the sharp rise in inflation paired with a policy rate that’s simply not doing enough to compensate for the rising risk premium. The Bangko Sentral ng Pilipinas (BSP) has kept rates at 4.50%, which, in my opinion, is a recipe for further weakness.

A detail that I find especially interesting is how this reflects a broader trend in emerging markets: central banks often find themselves behind the curve when it comes to inflation. The PHP’s vulnerability isn’t just about external factors like higher US yields or oil prices—it’s about a domestic policy framework that’s failing to keep up with the challenges.

India’s Balancing Act

The INR, meanwhile, is in a bit of a different position. The Reserve Bank of India (RBI) has been actively intervening to stabilize the currency, and there’s talk of potential rate hikes. But here’s the catch: if the Iran conflict persists and oil prices stay above $100/bbl, even these measures might not be enough.

What many people don’t realize is that India’s economy is uniquely sensitive to oil prices due to its heavy reliance on imports. This raises a deeper question: can the RBI’s interventions and rate hikes truly offset the impact of sustained high oil prices? Personally, I think it’s a risky bet, especially when geopolitical tensions show no signs of easing.

The Broader Implications: A Warning Sign for Emerging Markets

If you take a step back and think about it, the pressure on IDR, PHP, and INR isn’t just a regional issue—it’s a warning sign for emerging markets globally. Higher US yields, elevated oil prices, and geopolitical uncertainty are creating a toxic mix that could spill over into other economies.

One thing that immediately stands out is how this highlights the fragility of economies that are heavily dependent on external factors. From my perspective, this is a wake-up call for policymakers to strengthen domestic fundamentals and reduce vulnerability to external shocks.

Final Thoughts: Navigating the Storm

As I reflect on this, I’m struck by how interconnected these challenges are. It’s not just about currencies—it’s about the broader economic and geopolitical landscape. What this really suggests is that we’re in for a period of heightened volatility, and countries like Indonesia, the Philippines, and India will need to navigate this storm with careful policy measures and a bit of luck.

Personally, I think the key takeaway here is that while external factors like US yields and oil prices are important, it’s the internal weaknesses—fiscal deficits, inflation, policy missteps—that will ultimately determine how these economies fare. If there’s one thing this situation teaches us, it’s that resilience starts at home.
