Suppressed volatility: Kenya’s managed shilling faces its IMF moment

With record reserves masking two years of near-frozen exchange rates, a resumption of IMF programme talks could force Nairobi into a reckoning it has so far carefully avoided

By Grace Wanja

Kenya’s shilling has barely moved in more than two years. It stood at KSh129.45 per dollar in the week to 10 September, according to the most recent Central Bank of Kenya (CBK) data — a rate that would not look out of place in a snapshot from 2024. Over the same period, the central bank has accumulated foreign exchange reserves to an all-time high of $15.4B, providing what officials describe as a comfortable cushion against external shocks.

To most casual observers, this looks like stability. To analysts at EBC Financial Group, it looks like managed calm — and the distinction matters enormously as Kenya navigates unresolved IMF programme negotiations that could redefine the terms on which that stability is maintained.

“Suppressed volatility is deferred volatility, not absent volatility,” said David Precious, Senior Market Analyst at EBC Financial Group. “Kenya’s reserve position is genuinely strong, and that is worth saying plainly. A nominal rate that does not move, however, does not mean the pressure has gone. It means the pressure has moved: into the reserve line, into what importers pay, and into the real exchange rate as domestic inflation runs underneath a flat nominal one. For anyone holding shilling exposure, the implication is that two years of low realised volatility is a poor guide to forward risk.”

A reserve build of historic proportions

The headline numbers are striking. Kenya’s usable foreign exchange reserves surged by $1.55B in the week to 30 July 2026, jumping to $15.4B from $13.85B a week earlier and lifting import cover from 5.9 months to 6.4. The CBK attributed the increase largely to capital inflows from the government’s partial divestiture of its Safaricom stake: a 15 per cent shareholding sold to Vodafone Kenya Limited, a subsidiary of South Africa’s Vodacom, for approximately KSh204.3B, with proceeds placed in the National Infrastructure Fund held at the CBK.

Reserves eased modestly in subsequent weeks — to $15.155B on 20 August, $14.934B on 27 August, and $14.88B on 3 September — before rebounding by $371M to $15.253B in the week to 10 September, restoring import cover to 6.3 months. At no point did reserves fall below the four-month statutory minimum.

A further inflow remains possible following the CBK’s 28 August approval of Nedbank Group’s proposed acquisition of a 66 per cent stake in NCBA Group, a transaction valued at KSh116.3B. The reserve impact, however, may be limited: under the published terms, tendering shareholders receive 4.02994 Nedbank shares plus KSh2,100 in cash for every 100 NCBA shares held, meaning the bulk of the consideration is in stock rather than dollars.

Speaking in April, when reserves stood above $13B and external pressures were building across exports, remittances and tourism, CBK Governor Kamau Thugge said the bank had deliberately strengthened its buffers in anticipation of precisely such shocks. By conventional adequacy benchmarks, Kenya’s current reserve position is comfortable. The harder question is what those reserves are being used to achieve.

Treasury’s uncomfortable admission

What distinguishes Kenya’s situation from ordinary currency stability is that senior officials have effectively said the rate is not purely market-determined. Treasury Cabinet Secretary John Mbadi said publicly in late 2025 that the shilling could trade at around KSh118 to the dollar if left to move freely, citing an improving current account and stronger export performance. He and Principal Secretary Chris Kiptoo have separately indicated that, without CBK dollar purchases to build reserves, the currency could have appreciated to between KSh118 and KSh120. Mbadi has rejected the language of manipulation, attributing the shilling’s steadiness to higher diaspora remittances, improved export earnings, and government-to-government fuel procurement that reduced dollar demand in the open market.

Parliament’s own technical research arm reached a similar conclusion. The Parliamentary Budget Office, in its February 2026 report Budget Options for FY 2026/2027 and the Medium Term, noted that the shilling had remained broadly stable against the dollar while weakening roughly 6.5 per cent against the pound over the year to June 2025. The report described the pattern, set against normal emerging-market volatility, as pointing to tight exchange rate management or active liquidity smoothing by the CBK.

The CBK’s stated position is that Kenya maintains a flexible exchange rate regime and that the central bank intervenes only to smooth excessive volatility. It attributes the shilling’s stability to a stronger current account, higher foreign direct investment, overseas purchases of local-currency bonds, and improved reserve adequacy. Because the CBK does not publish the volume or timing of its foreign exchange market operations, the official account and the Treasury officials’ comments cannot be reconciled from public data alone.

Where the pressure goes instead

A managed nominal rate does not eliminate adjustment. It redirects it — and that redistribution carries real commercial consequences.

If the free-float level is KSh118 to KSh120, as Treasury officials have indicated, then at KSh129.45 as of 10 September, the shilling is roughly seven to nine per cent weaker than the government’s own estimate of where an unmanaged market would price it. Every dollar of imports costs Kenyan buyers that premium in shilling terms — a difference that passes directly into domestic prices for fuel, fertiliser, pharmaceuticals, and industrial inputs. The cost lands unevenly: importers and dollar-denominated borrowers absorb it, while exporters and recipients of diaspora remittances benefit from a weaker conversion rate.

The second channel is the real exchange rate. A nominal rate held flat while domestic inflation rises produces real appreciation regardless of what the screen shows. Kenyan headline inflation climbed from 4.3 per cent in February 2026 to 6.6 per cent in August, driven by energy and transport costs. Nominal stability is therefore doing progressively less for export competitiveness than the unchanged rate suggests, and the gap accumulates quietly rather than resolving through visible currency movement.

The IMF question

An IMF staff team visited Nairobi from 24 February to 4 March 2026 for technical discussions on a successor economic programme. Thugge confirmed that talks continued into August, but no new agreement, loan amount, or board approval date has been announced. The Fund’s most recent completed Article IV consultation — covering 2023 and concluded by the Executive Board on 17 January 2024 — stated that greater exchange rate flexibility and addressing foreign exchange market distortions would help keep Kenya’s external position in balance.

That is general policy guidance, and it predates the current period of stability. It also remains the most recent full Fund assessment available: the 2025 Article IV consultation was rescheduled at Kenya’s request so that programme discussions could be prioritised, meaning no full IMF assessment covering the current exchange rate arrangement has been published. If a new programme is agreed and carries conditionality along the lines of that earlier guidance, the arrangement described by Kenya’s own Treasury becomes a subject of negotiation rather than domestic discretion.

The test ahead

For EBC’s Precious, the measure of success in any transition is not a stronger or weaker shilling — it is a shilling that can move without triggering a crisis of confidence.

“It would be a rate that can move two or three per cent either way without being read as a loss of control, supported by published intervention data so participants can tell smoothing from steering,” he said. “Kenya has spent two years building the buffer that makes that affordable. If a programme arrives with flexibility conditions attached, the test will not be whether the shilling moves. It will be whether a move is read as policy working rather than policy failing.”

The market question, in the end, is one of sequencing: whether flexibility is introduced from a position of reserve strength and on Kenya’s own timetable, or later, under external conditionality, and with less room to manage the narrative. Two years of carefully preserved calm may be about to meet its most significant test.
