Colombian Peso's Volatility Amid Presidential Election Runoff

Colombia’s peso moved from acute depreciation pressure in April and May to a sharp pre-runoff rally by mid-June, turning the currency into a real-time barometer of election risk, domestic bond flows, and inflation expectations. By June 10, 2026, the peso was trading around COP 3,556-3,560 per US dollar, materially stronger than the levels above COP 3,800 seen only weeks earlier, and it continued strengthening in subsequent sessions. The most consequential development was the market’s post-first-round repricing after the May 31 presidential first round, when investors pushed the peso sharply higher ahead of the June 21 runoff, easing immediate imported-inflation pressure and improving sovereign financing optics. Even so, the path to that rally was highly unstable, and later September volatility showed that the underlying sensitivity of FX and TES debt markets to political and fiscal signals did not disappear.

From April Slippage To Early Stabilization

The first clear warning sign came on April 16, when the Colombian peso depreciated 2% against the US dollar. That move established the event’s initial direction: a weaker peso raising concern over inflation pass-through, debt-service costs, and whether the Banco de la República might need to adjust its intervention posture.

A modest reprieve followed on April 20, reported on April 21, when the peso appreciated to COP 3,573.30 per dollar from COP 3,593.14. Reporting tied that improvement to new economic growth data and an external risk-relief factor, a ceasefire between Israel and Lebanon, indicating that Colombia’s currency was already trading on a mix of domestic macro signals and global sentiment. At that point, the tracked scores sat at risk 25 / impact 35, suggesting manageable but visible market sensitivity.

By April 24, the dollar opened lower, and local reporting described the peso as showing signs of stabilization. That mattered less as a definitive trend change than as an early signal for central-bank watchers: if the market could self-correct, the immediate case for intervention weakened. Even so, the scoring moved to risk 35 / impact 40, implying that analysts still saw the currency as vulnerable despite the calmer session.

May Selloff Put Inflation And Policy Credibility In Focus

The picture deteriorated sharply in May. On May 9-10, reporting showed the peso at COP 3,747.10 per dollar. One update described that as the peso’s highest level against the dollar in more than two months, meaning a weaker peso in practical terms, while another noted a 0.48% daily increase in the exchange rate, reinforcing the sense that depreciation pressure was building. The risk-impact mix around those updates hovered between 40/35 and 35/40, reflecting a market that was becoming more unstable but not yet disorderly.

The real stress point came on May 13, when the exchange rate was reported at COP 4,200 per dollar, a 2% decline from the previous day. That was the most severe single datapoint in the sequence and was attributed to global market volatility and domestic economic indicators. Risk rose to 45, with impact at 40, marking the event’s first clear high-alert phase.

Pressure remained elevated over the following sessions:

- On May 14, the peso weakened further to COP 3,794.91, a 0.53% depreciation. - On May 15, reporting said the peso had fallen 5.18% over 30 days, from COP 3,608.10 on April 14 to COP 3,794.91 on May 14. - On May 17, the dollar closed near COP 3,796 after moving back above COP 3,800 intraday, with the move linked to higher global risk aversion tied to Middle East tensions. - On May 19, the dollar again opened above COP 3,800, reaching its highest levels since December.

This stretch is where the event’s macro significance became clearest. For Colombia, a weaker peso directly threatened to raise import costs and feed inflation, which in turn could complicate monetary policy. The per-perspective framing is explicit: from a CO:macroeconomics standpoint, sustained depreciation could force the central bank to accelerate intervention decisions to stabilize the currency and contain inflationary pressure. At the same time, the market implications broadened beyond spot FX. Higher dollar levels also increased scrutiny of local debt pricing and sovereign financing conditions, especially as investors reassessed risk premiums.

TES Flows And Election Positioning Reversed The Trend

The first meaningful reversal appeared on May 21, reported on May 22, when the peso strengthened and the dollar closed below COP 3,700. This was not framed as a generic rebound. Local coverage specifically tied the move to TES sovereign debt trading and election-related positioning, making clear that domestic bond flows and political risk had become the dominant pricing drivers. The score fell to risk 34 / impact 31, indicating reduced immediate stress.

That improvement did not proceed in a straight line. On May 24, reported on May 25, the peso recorded its sharpest daily move of the month, with the dollar falling below COP 3,660 ahead of the May 31 presidential vote. Despite the stronger peso level, the update raised risk to 44 and impact to 38 because the speed of the move itself increased short-term volatility risk. In other words, the concern shifted from one-way depreciation to unstable repricing around a known political event.

By May 26, reported on May 27, the official exchange rate showed the dollar below COP 3,650. That further appreciation modestly eased concerns over imported inflation and sovereign financing conditions, and the score dropped to risk 24 / impact 28. The market was signaling that, absent a policy shock, near-term conditions had improved.

This phase is critical because it changed the analytical frame. Earlier in May, the question was whether the central bank might need to defend the peso against a selloff. By late May, the more relevant issue was how election positioning and TES flows were amplifying currency moves in both directions. For Colombia’s markets desk, that meant broader sensitivity across asset classes, not a simple FX story. The CO:markets perspective underscores that point: simultaneous moves in FX and sovereign debt narrow room for policy complacency because fiscal-credibility concerns can feed both peso volatility and government borrowing costs.

First-Round Election Result Triggered A Sharp Repricing

The strongest break in the trend came immediately after the May 31 presidential first round. On June 1, reported on June 2, Colombian financial markets moved sharply, with the peso strengthening and the dollar closing near COP 3,556-3,560, well below the day’s official reference rate. That repricing materially changed the near-term backdrop for FX, inflation, and sovereign financing ahead of the June 21 runoff. The score moved to risk 38 / impact 44: risk remained elevated because politics still dominated pricing, but impact rose because the move was large enough to alter macro assumptions.

The rally extended through the next two weeks:

- On June 10, the peso posted another gain, with the dollar closing COP 6.64 lower, as TES trading and runoff uncertainty continued to shape pricing. - On June 11, reported on June 12, the dollar fell below COP 3,500, its lowest close in roughly five years. - On June 13, financial press reported the peso trading in the COP 3,400-per-dollar range, another multi-year high. - On June 14, reporting clarified that the peso had strengthened to around COP 3,400 on June 13 after closing near COP 3,475.78 on June 12.

These were not cosmetic gains. A move from the high-COP 3,700s and above COP 3,800 in May into the COP 3,500s and then COP 3,400s by mid-June materially reduced immediate depreciation pressure. It also changed assumptions about inflation pass-through, external competitiveness, and whether the central bank needed to respond to FX volatility at all. The risk score stayed around 34-38, while impact remained high at 42, reflecting that the market was no longer under acute selloff stress but was still being powerfully driven by political expectations.

For domestic stakeholders, the implications diverged:

- Monetary authorities gained breathing room on imported inflation as the peso strengthened. - The sovereign debt market benefited from improved financing optics, but only insofar as TES demand held up. - Export-sensitive sectors faced a less favorable exchange-rate backdrop as the peso appreciated. - Political actors and investors treated the runoff as the next decisive catalyst, meaning the rally remained conditional rather than fully anchored.

Post-Runoff Strength Held Through July Before September Volatility Returned

The peso’s strength persisted after the runoff period into early July. On July 3, Colombia’s official representative market exchange rate (TRM) was reported at COP 3,427.07 per dollar, described as the strongest level in five years. The score dropped to risk 24 / impact 28, consistent with a market that had moved out of immediate stress territory.

On July 8, reported on July 9, the peso opened stronger again, with the dollar down COP 13.37. Reporting attributed the move to higher oil prices and the market’s reaction to recent inflation data. That was important because it showed the currency was no longer trading only on election dynamics; commodity support and macro releases were again exerting influence. Risk and impact eased further to 22 / 24, the calmest reading in the sequence.

But the later updates show that the event’s underlying vulnerability never fully disappeared. On September 24, reported on September 25, the peso weakened sharply in the spot market as the dollar closed at COP 3,349.30, which was COP 134.3 above the prior close, while the official TRM stood at COP 3,264.39. That gap signaled a meaningful 24-hour deterioration in market sentiment and pushed the score back up to risk 42 / impact 36.

A day later, on September 25, reported on September 26, the peso ended a nine-session weakening run, but the reversal was only partial. The dollar touched COP 3,377.80 intraday before closing near COP 3,312. At the same time, TES sovereign bonds weakened, with yields on 2028, 2033, and 2050 maturities ending higher. This is the clearest confirmation of the broader market-risk perspective: the issue had spread from currency volatility into sovereign financing conditions and fiscal-credibility pricing. Even after the peso’s mid-year rally, markets remained ready to reprice Colombia quickly when confidence wavered.

Outlook

The peso’s move from April-May stress to June-July strength showed how quickly Colombian markets can reprice when election expectations, TES flows, and macro data align. The key watchpoints remain the same: whether political developments around the presidential runoff and its aftermath continue to drive FX direction, whether Banco de la República signals any discomfort with exchange-rate volatility, how inflation responds to the stronger peso, and whether TES demand remains firm enough to prevent renewed spillover into sovereign funding costs.

If the peso holds near stronger levels, imported-inflation pressure should stay contained and policy space will widen. If volatility returns alongside higher TES yields, the signal will be that Colombia’s market stress has shifted from a pure FX story to a broader confidence and fiscal-premium problem.
