Philippine central bank governor Eli Remolona sits in his Manila office promising as many rate hikes as it takes to defend the peso. Half a world away, India's chief economic adviser insists the rupee is fundamentally undervalued at current levels. Both statements sound like policy confidence. Both are admissions of defeat. The emerging markets currency wars have begun in earnest, triggered not by traditional trade flows but by an unexpected accelerant: AI infrastructure spending that is hoovering up dollars faster than emerging economies can earn them. When Nvidia invoices land in pesos or rupees, someone has to find the dollars to pay them. That hunt is reshaping global capital flows in ways that make the 1990s Asian financial crisis look quaint. Central banks across emerging markets now face a choice between defending their currencies through growth-killing rate hikes or accepting devaluation that imports inflation directly into grocery baskets already under stress.
The numbers reveal the trap. The Philippines raised rates again this week, with Remolona explicitly citing oil price spillovers from Middle East tensions as justification. But dig deeper and the real pressure comes from elsewhere: Philippine companies have committed $2.8 billion to AI infrastructure projects over the next 18 months, all payable in dollars. The peso has weakened 8% against the dollar since January, making every server rack and GPU cluster more expensive in local terms. India faces the same mathematics. The country's AI spending commitments total $47 billion through 2027, according to government estimates. That includes everything from Reliance's data centre expansions to state-backed semiconductor facilities. Every dollar needed for these projects must be earned through exports or borrowed, creating persistent downward pressure on the rupee. When India's chief economic adviser calls the currency "fundamentally undervalued," he is not making an academic point about purchasing power parity. He is describing a balance of payments problem disguised as a growth opportunity. , - The carry trade revival tells the other half of the story. DoubleLine Capital and Van Eck are among investors rediscovering currency strategies that borrow in low-yielding currencies to invest in higher-yielding ones. Volatility has collapsed as Middle East ceasefire talks steadied markets, making these trades more attractive. But emerging market central banks are the counterparty to this flow, forced to offer higher rates to attract the capital they need. The Philippines' benchmark rate now sits at 6.5%, India's at 6.75%. Both countries are paying premium rates to fund the dollar requirements of their own growth strategies. Briefed's Consumer Signals data shows UK discount-seeking behaviour hitting 86.8 this week, well above the 70-point alert threshold. This matters because currency weakness in emerging markets eventually flows through to UK inflation via supply chains and commodity prices. When the peso weakens, electronics assembly costs rise. When the rupee falls, IT services become more expensive in sterling terms. The interconnection runs both ways, but emerging markets absorb the volatility first. , - The policy responses reveal how few good options remain. The Philippines can raise rates to defend the peso, but higher borrowing costs choke the domestic investment needed to build AI infrastructure. India can let the rupee weaken to maintain competitiveness, but imported inflation hits consumers already facing food price pressures. Both countries are trapped between growth and stability, with AI spending commitments acting as the mechanism that forces the choice. Carry traders understand this dynamic better than most policymakers. They are not betting on economic fundamentals or political stability. They are betting on desperation. Emerging market central banks need foreign capital to fund dollar-denominated investments, creating predictable opportunities for investors willing to lend in hard currency and collect higher yields. The strategy works until it doesn't, but the mathematics of AI infrastructure spending suggest this particular trade has months, not weeks, to run. , - Watch the rupee first. India's AI commitments are front-loaded, with $18 billion in spending due over the next 12 months. If the rupee breaks through 85 to the dollar, expect coordinated intervention from the Reserve Bank of India. The Philippines has less breathing room, with foreign reserves covering just 3.2 months of imports at current burn rates. A sustained attack on the peso could force capital controls within quarters, not years. The broader lesson applies beyond currency markets. When technology infrastructure requires dollar-denominated imports, emerging economies become structurally short the global reserve currency. AI spending is creating the same dynamic that oil imports generated in the 1970s, but with less policy flexibility and more complex supply chains. Central banks can raise rates to defend their currencies, but they cannot print the dollars their economies increasingly need to function. That constraint will reshape global capital flows long after the current bout of rate hikes ends.
