American consumers lost more ground to inflation in January 2026, as prices climbed 2.4% over the prior 12 months, while international data show the dollar’s share of global reserves has been edging lower over time. The squeeze on household budgets arrives alongside federal projections of roughly $1.9 trillion in annual deficits in fiscal 2026, raising a pointed question: can the greenback maintain its global standing if the fiscal math keeps deteriorating?
Grocery Bills and Rent Keep Climbing
The Consumer Price Index for All Urban Consumers rose 0.2% on a seasonally adjusted basis in January 2026, according to the official CPI release published by the Bureau of Labor Statistics on February 13, 2026. Over the previous 12 months, the index increased 2.4%. Shelter costs, which make up roughly a third of the CPI basket, jumped 0.4% in the month, and food prices rose 0.3%. Energy offered a slight reprieve with a small decline, but not enough to offset the pressure on the categories that dominate most family budgets. For households that rent and spend a large share of income on groceries, even modest monthly increases compound into a noticeable hit to disposable income over the course of a year.
What those percentages mean in practice is straightforward: a basket of goods that cost $100 a few years ago now costs measurably more, and wages have not always kept pace. The long-run CPI series maintained by the Federal Reserve Bank of St. Louis allows anyone to trace how the purchasing power of a single dollar has eroded year by year, turning small annual changes into a sizable cumulative loss. While headline inflation has cooled from the spikes of 2022 and 2023, today’s 2.4% annual increase is layered on top of those earlier surges. The result is that many families feel as if they are running in place: paychecks may be rising in nominal terms, but the cost of keeping a roof overhead and food on the table keeps climbing just as fast, if not faster.
The Dollar Still Dominates Trading, but Reserves Tell a Different Story
Despite persistent talk of de-dollarization, the greenback’s role as the world’s primary transaction currency remains enormous. In the Bank for International Settlements’ 2025 Triennial Central Bank Survey (reference date April 2025), the BIS reported that the dollar was on one side of 89.2% of all foreign-exchange trades, underscoring its central place in global markets; the BIS turnover data show the dollar’s share has remained very high across survey years. That dominance reflects the dollar’s deep integration into cross-border payments, commodity pricing, and corporate hedging. Oil contracts, aircraft purchases, and emerging‑market bonds are still overwhelmingly quoted and settled in dollars, and global banks rely on dollar funding markets for day‑to‑day liquidity.
Reserve holdings, however, show a different trajectory. According to the IMF’s Currency Composition of Official Foreign Exchange Reserves (COFER) dataset, the dollar’s share of allocated reserves was about 58% as of the first quarter of 2025, down from higher levels in prior decades (see IMF COFER). Some of that decline reflects mechanical valuation effects: when the dollar weakens against other currencies, the non‑dollar portion of reserves grows in dollar terms even if no central bank actively sells greenbacks. But diversification is also deliberate. Central banks in Asia, the Middle East, and parts of Europe have been gradually adding gold, euros, and Chinese renminbi to their portfolios, even as they continue to rely on dollars for settlement. The IMF’s October 2025 global stability report emphasizes that this slow drift does not yet amount to a wholesale shift away from the dollar, but it does signal a desire to hedge against U.S.-specific policy and fiscal risks.
Deficits, Debt Sustainability, and Foreign Appetite for Dollars
The fiscal backdrop adds pressure to that gradual diversification. The Congressional Budget Office’s February 2026 Budget and Economic Outlook projects that the federal deficit will total roughly $1.9 trillion in fiscal year 2026, with shortfalls remaining elevated for years to come (see CBO outlook). Persistent borrowing at this scale means the Treasury must continuously attract buyers for new debt, and that depends in part on foreign confidence in dollar‑denominated assets. As interest payments consume a larger share of federal spending, investors are paying closer attention to whether U.S. policymakers can stabilize the trajectory of debt relative to the size of the economy.
For now, foreign appetite remains solid. The Treasury Department’s International Capital data for December 2025 showed ongoing net purchases of U.S. securities by both private and official investors abroad, providing a steady inflow of capital that helps keep borrowing costs manageable. But the tension between an ever‑growing supply of Treasury bonds and a slowly shrinking share of dollar reserves creates a potential feedback loop. If foreign holders begin to demand higher yields to compensate for perceived fiscal and inflation risk, the cost of servicing the debt will rise, widening future deficits and potentially undermining confidence in the currency. That dynamic would not overturn the dollar’s global role overnight, but it could gradually erode the “exorbitant privilege” that has long allowed the United States to borrow more cheaply than its peers.
From Exchange Rates to Household Prices
The connection between global reserve trends and a family’s grocery bill runs through the exchange rate. The Federal Reserve tracks a set of trade‑weighted dollar indexes that measure the currency’s strength against major U.S. trading partners. When the dollar is strong, imports become cheaper in local‑currency terms, which helps restrain domestic prices on everything from electronics and clothing to furniture and some food products. A weaker dollar has the opposite effect: it raises the cost of imported goods and inputs, and those increases tend to be passed along to consumers over time. If a gradual shift in reserve holdings eventually reduces demand for dollar assets, it could put downward pressure on the currency and add another layer of inflation to already‑stretched household budgets.
That risk is particularly salient for lower‑income households, which spend a larger share of their income on tradable goods and essentials. While many services, such as haircuts or local childcare, are priced in largely domestic markets, items like apparel, consumer electronics, and some processed foods are deeply embedded in global supply chains. A sustained depreciation of the dollar would make those goods more expensive, amplifying the impact of domestic price increases in shelter and healthcare. Policymakers monitoring inflation therefore need to look not only at the latest CPI print, but also at the underlying drivers of dollar demand in global finance, including fiscal policy choices and the evolving preferences of foreign central banks.
Data, Policy Choices, and the Dollar’s Next Chapter
Understanding how these forces interact requires more than headline statistics. The Bureau of Labor Statistics’ interactive inflation calculators let consumers and analysts break down price changes by category, revealing how much of the recent squeeze comes from rent, groceries, transportation, or medical care. Paired with historical CPI data and exchange‑rate indexes, these tools show that even “moderate” inflation can significantly erode living standards when it compounds over several years and when wage growth is uneven across sectors and regions. They also highlight that the inflation experience is not uniform: urban renters, suburban homeowners, and rural households face different mixes of price pressures depending on their consumption patterns.
On the international side, the durability of the dollar’s role will hinge on policy credibility as much as on market inertia. The BIS foreign‑exchange survey, IMF reserve data, and Treasury capital‑flow reports all point to a currency that is still unrivaled in its day‑to‑day functions but no longer completely unchallenged as a long‑term store of value for official investors. If U.S. fiscal policy remains on an unsustainable path and inflation periodically flares, more central banks may feel compelled to diversify further, even if they continue to rely on dollars for transactions. Conversely, credible steps to narrow deficits, anchor inflation expectations, and maintain deep, open capital markets would reinforce the dollar’s status and help shield American households from the worst inflationary spillovers of any future reserve shifts. For now, consumers are left navigating higher rents and grocery bills in an environment where both domestic policy and the world’s confidence in the greenback are very much in flux.
