Horror stories of inflation in Argentina

The solution could require ‘the madman’ with a chainsaw. People adapt.

By David Enna, Tipswatch.com

During my recent visit to Argentina I asked a tour guide in Buenos Aires about inflation, because that’s a topic that always interests me.

Guide: “Inflation in Argentina is improving. It was down to 2.2% in January.”

Me, being ignorant: “2.2% annual inflation? That’s great.”

Guide: “2.2% a month.”

Ouch. I should have been more aware of the traumatic issue of inflation in Argentina. It is so dangerous and ingrained that the Buenos Aires Herald ran this headline on Feb. 13: “Argentina annual inflation plunged to 84.5% in January 2025.” Plunged to 84.5%.

Since I returned, the nation reported February inflation at 2.4% for the month, up a bit from January. But annual inflation dropped to 66.9%, the lowest since July 2022. Here is the annual trend over the last 8 years:

As recently as July 2024, annual inflation was running at 266% in Argentina. It has been coming down recently in the wake of the November 2023 presidential election of Javier Milei, a libertarian who has made sweeping cuts in government spending. His approach is known as “shock therapy” and includes reductions in public sector jobs, subsidies, food aid, along with freezing wages and pensions.

Milei, a self-described “anarcho-capitalist,” is famous for wielding a chainsaw in public (and for giving one to Elon Musk recently at a Conservative Political Action Conference in the U.S.). He told that group: “The only rational path is to shrink the size of the state as much as possible.”

Although inflation is declining rapidly in Argentina, Milei seems to be somewhat unpopular in a country that swings from left to right with every major election. Wage and pension controls — at a time of continuing high inflation — have recently triggering violent demonstrations.

Milei, 54, is known in Argentina by both critics and supporters as “El Loco,” the madman. Milei claims he hasn’t combed his hair since he was 13, adding: “From that moment on, the invisible hand combs my hair.” From a 2023 The Sun report:

A biography, El Loco, by journalist Juan Luis Gonzalez, told of Milei’s affection for his dogs, claiming he uses a spiritualist to seek guidance from his beloved English mastiff Conan, who died in 2017 and has been cloned four times.

Also, Milei created a huge controversy last month by endorsing a meme coin called $Libra on the day it was launched. Within 40 minutes, its market value soared to about $4.5 billion. Hours later, its value plunged by about 89% and the president “unendorsed” it. A criminal investigation is under way.

Wretched economic history

I certainly can’t explain how Argentina got into this economic mess, but Milei didn’t cause it. These problems have existed for decades. Rampant government spending and massive government borrowing are two important factors. The government has defaulted on its debt nine times. Argentina’s currency was devalued by 30% in 2015, and then again in 2016. Soon after taking office in December 2023, Milei devalued the peso by more than 50%. From an Associated Press report:

The South American country’s economy is such a basket case — and has been for so long — that many analysts believe that only such radical measures offer a realistic opportunity to rescue the economy. What makes his challenge so difficult is that Milei’s plan seems certain to make people’s lives worse long before they get better.

What does this mean for a typical Argentinian?

Our guide in Buenos Aires, Karla, talked about how people cope with out-of-control inflation. Some of her insights:

No sense in saving money. Got money? Spend it, because its value is going to decline dramatically over time. For this reason, you still see crowded shops and restaurants. In many cases, people pay with wads of cash.

CD rates. Karla said most people in Argentina would not consider putting money in a bank for longer than one month. Too risky. A one-month CD today is paying an annual rate of about 27%, but that remains well below the inflation rate of 67%.

Getting a loan. Who is going to lend you money when inflation is rising 67% a year? Getting a car loan or home mortgage is very difficult, and the interest rates would be severe over time. From the site TheLatinInvestor.com:

In Argentina, most transactions are conducted using cash, primarily in the form of US $100 bills. It sounds primitive but this is how it is.

Banking. People in Argentina don’t trust banks, and the country has a history of widespread bank failures as recently as 2001. U.S. banks don’t have operations in Argentina because of the unpredictable nature of the economy. This makes it a difficult environment for foreign investment.

U.S. dollars are popular. For people who can afford it, exchanging pesos for dollars is highly desirable. The current exchange rate is about 1,069 pesos to $1. In March 2023, that number was 200. For major purchases like cars or homes, $100 bills are often the desired payment method. From a New York Times article:

Nearly every big purchase in Argentina — land, houses, cars, expensive art — is done in tall stacks of U.S. currency. To save up, Argentines stuff bundles of American bills into old clothes, beneath floor boards and in bombproof safe deposit boxes past nine locked gates and five stories beneath the ground.

A sense of normalcy?

Argentina’s poverty rate has recently soared to 57% amid Milei’s austerity measures and currency devaluation. But life goes on. Prosperous areas of Buenos Aires look much like anywhere in Europe, with elegant shopping, cafes, nightlife. Many people have adapted to extremely high inflation and just hope for a solution.

Argentinians have lived with high inflation for decades. They have learned to survive, even in this harsh reality. From a recent discussion on Reddit:

We have some ways to mitigate inflation, but at the end it destroy us anyways. The things we do are: Spend the pesos as fast as we can in anything that will maintain or gain value against inflation, lower our lifestyles as the inflation surges, and the principal method for saving or planing long term is buying dollars or euros, most Argentinians have savings in dollars. …

All income is disposable income when saving makes no sense. What it destroys is any kind of long-term planning.

Most people will never be able to afford a house of their own for example, or a brand new car.

My motto for buying things is “If you have the money and want/need that, buy it now, tomorrow it will be more expensive.”

In the United States, we recently went through a very brief period of 9% annual inflation, which dropped to half that within a year. Yet, this was somewhat traumatic for a nation used to stable prices. Even today, as inflation drifts lower, many people are feeling the pain. But are we at the stage requiring a “chainsaw”? No, I’d say more like pruning shears.

Remember: Things are very good here. We have a good thing. And yes, inflation is an enemy we must resist.

10-year TIPS reopening auction gets real yield of 1.935% after Fed-triggered dip

By David Enna, Tipswatch.com

Over the years, I have been known to rail against Federal Reserve commentary coming on the eve of auctions of Treasury Inflation-Protected Securities. So often, it seemed, a fairly attractive auction ended up with a mediocre real yield, thanks to the Fed.

This more or less happened yesterday, with Federal Reserve Chairman Jay Powell issuing a remarkably mixed message: 1) we can (possibly) expect two more rate cuts this year, 2) we can (probably) expect higher inflation this year and next, and 3) we can (probably) expect slower economic growth and higher unemployment this year and next.

Given all that, the Fed decided to hold short-term interest rates at current levels but also to slow down the pace of its balance-sheet reductions, which could help lower longer-term interest rates.

To me, that message seemed to forecast “stagflation,” a combination of higher inflation and slower economic growth. But the stock and bond markets were pleased. For one day, stock prices surged higher and bond yields fell.

And the result could be seen in today’s Treasury offering of $18 billion in a reopened CUSIP 91282CML2, creating a 9-year, 10-month TIPS. Most of the week, this TIPS looked likely to get a real yield somewhere in the range of 1.98% to 1.99%, but today’s result was a bit lower: a real yield of 1.935%.

That’s not really so bad. This TIPS was trading on the secondary market earlier Thursday with a real yield of 1.87%, gradually rising to 1.91%. The “when-issued” prediction, revealed just before the auction’s close, was 1.93%. The bid-to-cover ratio was 2.35, indicating lukewarm demand.

In this case, my preview article’s advice to buy this TIPS on the secondary market earlier in the week was correct. Real yields of around 2.0% were available before Powell spoke. (But trust me, it doesn’t always work out that way.)

The truth: This auction result is not bad at all. A real yield of 1.935% is attractive by historical standards, even if it is a bit below recent trends. Here is the trend in the 10-year real yield over the last two years:

Click on image for larger version.

The longer-term trend shows more clearly the historic value of today’s higher real yields:

Pricing

CUSIP 91282CML2 carries a coupon rate of 2.125%, set by the originating auction on Jan. 23. Because today’s auctioned real yield came in below the coupon rate, investors had to pay a premium price of 101.685184. In addition, this TIPS will have an inflation index of 1.00639 on the settlement date of March 31.

With that information, we can calculate the investment cost of $10,000 par value at this auction.

  • Par value: $10,000.
  • Actual principal purchased: $10,000 x 1.00639 = $10,063.90.
  • Cost of investment: $10,063.90 x 1.01685184 = $10,233.50
  • + accrued interest of $44.30

To sum up, an investor purchasing $10,000 par value at auction paid $10,233.50 for $10,063.90 in principal. From then on, the investor will earn inflation accruals plus 2.125% interest on inflation-adjusted principal over the next 9 years, 10 months.

Inflation breakeven rate

With a 10-year nominal Treasury note yielding 4.23% at the auction’s close, this TIPS gets an inflation breakeven rate of 2.30%, a bit lower than recent trends. This means it will out-perform the nominal Treasury if inflation averages more than 2.30% over the next 10 years.

Here is the trend in the 10-year inflation breakeven rate over the last two years, showing the sharp decline in inflation sentiment in recent weeks:

Thoughts

Let’s be realistic: A real yield of 1.935% is fine, even if it falls a bit short of the coveted 2.0% mark. It’s a good return on a very safe investment, especially if held to maturity.

While I watched Powell’s news conference yesterday, I was fascinated by his repeated use of the term “uncertainty” when describing current economic conditions. He said:

“I don’t know anyone who has a lot of confidence in their forecast. Forecasting is always really, really hard. And in the current situation, uncertainty is remarkably high.”

From today’s Wall Street Journal report:

Officials projected weaker growth, higher unemployment and higher inflation than they had anticipated in December. Moreover, nearly all officials judged that if their forecasts were to be proven wrong, it would be in the direction of even softer growth, more joblessness and firmer price growth.

A combination of stagnant growth and higher prices, sometimes called stagflation, could make it harder for the Fed to cut interest rates this year to pre-empt any slowdown.

So should we expect big moves in Treasury yields in coming months? Definitely not in short-term rates, where the Fed will hold policy stable. Longer-term rates are “going with the flow,” and I have no idea where that flow is heading.

So getting an above-inflation yield of 1.935% for nearly 10 years on a very safe investment looks like a sensible path, at least for a portion of your overall portfolio.

Here is the history of 9- to 10-year TIPS auctions over the last four years:

Here’s another chance to get a 2% above-inflation yield for nearly 10 years

Treasury will auction a reopened 10-year TIPS on Thursday.

By David Enna, Tipswatch.com

March 20, 2025 update: 10-year TIPS reopening auction gets real yield of 1.935% after Fed-triggered dip

Real yields have been quite volatile through 2025, with the yield on a 10-year Treasury Inflation-Protected Security falling 54 basis points from a high of 2.34% on January 10 to a low of 1.80% on March 3. That’s a big drop.

But now things have turned around, with the 10-year real yield inching above 2.0% at the market close on Friday. That’s a positive development for investors leading into the Treasury’s reopening auction Thursday of CUSIP 91282CML2, creating a 9-year, 10-month TIPS.

This TIPS had an originating auction two months ago, at the time generating a real yield to maturity of 2.243%, the highest for this term in 16 years. The auction set its coupon rate at 2.125%, also the highest in 16 years.

CUSIP 91282CML2 trades on the secondary market, where it closed Friday with a real yield of 2.00% and a price of 101.09, which is at a premium because the market real yield has now dipped below the coupon rate of 2.125%.

Definition: The “real yield” of a TIPS is its yield above official future U.S. inflation, over the term of the TIPS. So a real yield of 2.0% means an investment in this TIPS would provide a return that exceeds U.S. inflation by 2.0% for 9 years, 10 months.

Opinion: If you can find 10-year TIPS with a real yield at or near 2.0%, it is a worthwhile investment, as long as you can hold to maturity. Yes, real yields could continue rising, but 2.0% is historically an attractive yield, as demonstrated in this chart showing the trend over the last 15 years:

Click on image for larger version.

Side note: Thursday’s auction size is $18 billion, the largest in history for a 10-year TIPS reopening auction. It is up 12.5% from the $16 billion size of the similar auction in March 2024. This does indicate the Treasury, and the bond market, are committed to TIPS.

And this: Although TIPS have been a fairly reviled investment since a highly negative year in 2022 (total return down 12.2%), this investment class has been doing well in 2025’s volatile markets. The TIP ETF — which holds the full range of maturities — has had a total return of 2.7% year to date, compared to -4.0% for the S&P 500.

Look to the secondary market

Because of the current volatility, I’d recommend skipping this auction (unless you wish to buy at TreasuryDirect) and look for attractive yields on CUSIP 91282CML2 on the secondary market, through your broker. A lot can change before Thursday’s auction closes at 1 p.m. ET. On the secondary market, you can lock in a real yield you find attractive.

Saturday morning, Fidelity was listing CUSIP 91282CML2 with a real yield to maturity of 2.01%. Of course, things will change by Monday. If you want to invest in this TIPS, it’s worth checking the secondary market.

The advantage of buying at auction, especially through TreasuryDirect, is that even small-lot purchases will get the auction’s high yield. The advantage of the secondary market is that you can see exactly the price and real yield you will be receiving. The negative is that you may face a small bid-ask spread. Most of the time, it doesn’t make a huge difference, but if you see a real yield you like, know that you can probably get it on the secondary market without dealing with the auction’s uncertainty.

Pricing

At Friday’s close, CUSIP 91282CML2 was trading with a price of 101.09. Plus, it will have an inflation index of 1.00639 on the settlement date of March 31. With that information, we can estimate the investment cost of $10,000 par value of this TIPS:

  • Par value: $10,000.
  • Actual principal purchased: $10,000 x 1.00639 = $10,063.90.
  • Cost of investment: $10,063.90 x 1.0109 = $10,173.60.
  • + accrued interest of about $43.

In summary, at Friday’s pricing, an investor would pay $10,173.60 for $10,063.90 of principal on the March 31 settlement date, and then earn accruals matching future inflation plus an annual coupon of 2.125% for 9 years, 10 months. This is just an estimate. The market will change by the Thursday auction.

Inflation breakeven rate

At Friday’s close, a 10-year Treasury note had a nominal yield of 4.31%, giving this TIPS an inflation breakeven rate of 2.31%, relatively high by historical standards but a bit lower than recent auctions of this term. Inflation over the last 10 years, through February, has averaged 3.1%.

Here is the trend in the 10-year inflation breakeven rate over the last 15 years, showing the recent stability in the area around 2.25%:

Click on image for larger version.

Thoughts

I was a buyer at the January auction, filling the amount I needed for the 2035 rung of my TIPS ladder. So I won’t be a buyer this week. As I noted above, investors could decide to skip this auction because of the uncertainty caused by volatility, and instead look to lock in an attractive real yield on the secondary market.

If you do make an investment on the secondary market, place a note in the comments to tell us how you did.

CUSIP 91282CML2 will be reopened again at auction on May 22, 2025, and then a new 10-year TIPS will be issued July 24.

This TIPS auction closes Thursday at 1 p.m. ET. Non-competitive bids at TreasuryDirect must be placed by noon Thursday. If you are putting an order in through a brokerage, make sure to place your order Wednesday or very early Thursday, because brokers cut off auction orders before the noon deadline.

I will be posting the auction results soon after the close on Thursday. Here is a history of auction results for this term over the last 5 years:

February inflation brings good news for markets

Annual rates for both all-items and core inflation fell from January levels and came in under expectations.

By David Enna, Tipswatch.com

Finally, some good news on inflation. The February inflation report just released by the Bureau of Labor Statistics shows inflation moderating, with annual rates for both all-item and core inflation declining.

All-items inflation, measured on a seasonally adjusted basis, came in at 0.2% for the month and 2.8% for the year. Core inflation, which removes food and energy, was 0.2% for the month and 3.1% for the year. This was below expectations, and also below January’s annual numbers of 3.0% for all-items and 3.3% for core.

The BLS noted that shelter costs rose 0.3% in February, accounting for nearly half the February all-items increase. Shelter costs were up 4.2% for the year, but the BLS noted that was the smallest 12-month increase since December 2021. Also from the report:

  • Food at home prices were unchanged for the month and up 1.9% for the year.
  • The price of eggs was up 10.4% for the month and a frightening 58.8% for the year.
  • Gasoline prices fell 0.9% and are now down 3.2% annually.
  • Electricity costs, however, were up 1.0% for the month and 2.5% for the year.
  • Costs of used cars and trucks rose 0.9% for the month but are up only 0.8% over 12 months.
  • New vehicle prices fell 0.1% for the month and are down 0.3% for the year.
  • Airline fares fell a sharp 4.0% for the month and are down 0.7% for the year.
  • Costs of motor vehicle insurance rose 0.3% for the month and are up 11.1% for the year.

Here is the 12-month trend in annual all-items and core inflation, showing how both all-items and core inflation broke lower in February, with core reaching its lowest annual level since April 2021:

What this means for TIPS and I Bonds

Investors in Treasury Inflation-Protected Securities and U.S. Series I Savings Bonds are also interested in non-seasonally adjusted inflation, which is used to adjust principal balances on TIPS and set future interest rates for I Bonds. For February, the BLS set the inflation index at 319.082, an increase of 0.44% over the January number.

For TIPS. The February inflation index means that principal balances for all TIPS will increase by 0.44% in April, after rising 0.65% in January. Keep in mind it is normal for early-year non-adjusted inflation to run higher than the adjusted CPI. That will reverse later in the year. Here are the April Inflation Indexes for all TIPS.

For I Bonds. February marks the fifth of a six-month string that will determine the I Bond’s new variable rate, which will be reset on May 1 and eventually roll into effect for all I Bonds. As of February, with one month remaining, inflation has increased 1.20%, which would translate to a variable rate of 2.4%. The March number seems likely to push that up to about 3.0%, much higher than the current 1.90%.

This trend is going to make I Bonds an interesting investment in 2025, potentially offering a composite rate of about 4.1% or 4.2% for six months, at a time when short-term rates could be declining. I’ll have more on that after the March inflation report is issued on April 10. Here are the data so far:

View historical data on my Inflation and I Bonds page.

What this means for future interest rates

The February inflation report provides good news for the Federal Reserve, with annual inflation finally moderating after increasing from 2.4% in September 2024 to 3.0% in January. As it stands, 2.8% for all-items and 3.1% for core remains too high. But the upward creep has ended.

There are still a lot of unknowns, with the effects of tariffs, federal layoffs, deportations and a potentially weakening economy lingering out there in our future. On balance, I’d say the possibility of short-term rate cuts in 2025 has been increasing. But the key question is: Can inflation continue moderating?

From this morning’s Bloomberg report:

While Wednesday’s report offers some relief, several measures still indicate that inflation is rearing back up again. And with President Donald Trump rolling out a series of tariffs, prices are expected to rise on a variety of goods from food to clothing, testing the resilience of consumers and the broader economy. …

“The combination of easing inflationary pressures and rising downside risks to growth suggest that the Fed is moving closer to continuing its easing cycle,” Kay Haigh, global co-head of fixed income and liquidity solutions in Goldman Sachs Asset Management, said in a note.

And the Wall Street Journal:

Wednesday’s report largely predates President Trump’s recent tariff actions, which means the full effect of the new tariffs aren’t captured.

My reaction is: This February inflation report takes a positive (but small) step toward lower inflation. A lot of uncertainty remains. The Fed will be on hold for the near term.

I Bond’s fixed rate could fall at May 1 reset. Or not.

5-year real yields are declining. What does it mean for TIPS and I Bonds?

By David Enna, Tipswatch.com

April 11, 2025, update: Welcome to the I Bond ‘buying season’

April 10, 2025, update: I Bond’s variable rate will rise to 2.86% on May 1

April 3, 2025, update: My I Bond fixed-rate projection just fell to 1.10%

I’ve just returned from 3+ weeks in very southern South America — much of the time with limited internet access — and gosh, you folks have been busy.

Tariffs on. Tariffs off. Stock market down, up, then down. Treasury yields all over the place. Although I could monitor news some of the time, I am a bit lost about what’s been happening.

During that time away, I had three interview requests from separate Wall Street Journal reporters, plus NPR and Bottom Line. Something was triggering interest. At least twice during the trip, I noticed the 5-year real yield had fallen midday to 1.30%, down from 1.74% when I left on February 10. Things have stabilized a bit, but volatility is obviously a key market factor in March 2025.

In this brief time, the real yield of a 5-year Treasury Inflation-Protected Security has fallen much farther than the yield of the 10-year TIPS. Note in this one-year chart how the two yields tracked closely until October 2024, and then have widened dramatically:

Click on image for larger version.

The gap between the current 5-year real yield (1.57%) and the 10-year (1.99%) has been partially caused by higher inflation expectations over the next 5 years, now at 2.57%, compared with the 10-year inflation expectation at 2.35%. For a long period of 2024, the 10-year inflation breakeven rate was running higher than the 5-year.

Markets are concerned about future inflation, and that increases demand for TIPS, which in turn lowers yields. From a Bloomberg article this week:

But rising inflation is a real possibility now even if many investors are bracing for rate cuts, said Nicolas Trindade, who runs a number of funds at AXA Investment Managers. He expects volatility to increase amid the unpredictable economic strategy.

“The main risk for 2025 is a sharp resurgence in US inflation on the back of tariffs, tax cuts and immigration restrictions that could lead the Fed to open the door to hiking interest rates again,” he said. “The market is definitely not priced for that.”

This comparison of the real yields is important now for several reasons:

  • On March 20, the Treasury will reopen a 10-year TIPS at auction. The real yield at this point would be 1.99%, a decline from 2.243% at the originating auction on Jan. 23. That’s down about 25 basis points.
  • Then, on April 17, a new 5-year TIPS will be issued at auction. At this point the real yield looks likely to be about 55 basis points lower than the 2.121% set in the last auction of this term, a reopening on Dec. 19, 2024.
  • And two weeks after that auction, the Treasury will reset the I Bond’s fixed interest rate for purchases from May to October 2025. My analysis of data through March 7 indicates the new fixed rate could hold at 1.20%, or potentially drop to 1.10%.

The 5-year real yield is key

The Treasury has never revealed a formula for setting the I Bond’s fixed rate, but it has stated it looks at real yield trends over time. TreasuryDirect has provided this cryptic information:

The Secretary of the Treasury, or the Secretary’s designee, determines the fixed rate. The rate is based on market rates that have been adjusted to account for the value of components unique to savings bonds. These include the early redemption put option, tax deferral feature, deferred purchase feature, and Treasury’s administrative costs.

I Bond watchers have observed that over the last decade one formula has accurately predicted the Treasury’s fixed rate decision: Apply a ratio of 0.65 to the average 5-year real yield over the preceding six months. This formula has worked without fail at least since 2017.

So now I am going to use that formula to look at how recent declining real yields could affect the Treasury’s May 1 decision. Here are the data:

I include the 10-year TIPS data in this chart simply as a back-check, but it is interesting to note that 10-year real yields would point to a higher fixed rate of 1.40%. (The fixed rate is always rounded to the one-tenth decimal.) But … ignore that. The 10-year real yield hasn’t been a reliable indicator of the rate reset.

At this point, as of March 7, 2025, the average real yield of a 5-year TIPS since November 1, 2024, has been 1.82%, much higher than the current rate of 1.57%. Applying a ratio of 0.65 to 1.82% gets you to 1.18%, which rounds to 1.20%, same as the current fixed rate.

So, yes, the fixed rate could hold at 1.20%.

But what if the 5-year real yield stays around this 1.57% level through April, or goes lower? If that happens, the I Bond’s fixed rate is likely to decline to 1.10%, at least. There are 57 market days remaining until late April. If you add in 57 days at 1.57%, the real yield average drops to 1.132%, which would round to 1.10%.

So, yes, the fixed rate could drop to 1.10%.

What we don’t know

The Trump administration could decide to ditch the long-standing formula for setting the I Bond’s fixed rate. That is certainly possible. Remember, there is no set formula required by law. Keep that in mind.

Or, maybe it could eliminate the savings bond program entirely, cutting off all new issues? Highly improbable, I’d say.

Also, real yields have been highly volatile over the last month and may continue to rise and fall unpredictably. We’ll have more certainty by mid-April.

Suggested strategy: Wait

Maybe you haven’t noticed, but I Bonds are getting more and more attractive as the 5-year TIPS yield declines. An I Bond can be redeemed after 5 years with no penalty, so it is directly comparable to a 5-year TIPS, but has advantages of tax deferral, better deflation protection and no market fluctuations.

An I Bond with a fixed rate of 1.20% is more attractive than a TIPS with a real yield of 1.30% or 1.40%, in my opinion. So if TIPS yields continue declining, I Bonds with a fixed rate of 1.20% — or even 1.10% — will remain attractive.

My opinion: The best strategy for investing in I Bonds in 2025 is to wait at least until April 10, when the March inflation report will be released. Then you will know for certain what the new variable rate will be (probably higher than the current 1.90%) and have a better idea of the potential fixed-rate reset.

I am thinking an investment near the end of April will make the most sense. There is no harm in waiting. But if the fixed rate looks likely to rise, May would be the better choice. I will have more to say on this topic in mid-April.
